A very interesting report that recently appeared on Mother Nature Network (MNN).
We live in Josephine County here in Southern Oregon. Our next door neighbours to the East are Jackson County. Josephine and Jackson Counties share one very noble attribute: each is only one of just nine GMO-free counties in the entire United States of America. Plus, as evidenced at our local Grants Pass Farmers’ Market every Saturday, the growing of organic fruit and vegetables is widespread in our county. We feel very happy to have ended up in this part of America.
All of which makes a logical introduction to a report that appeared on MNN on September, 1st. It is republished below.

For safer, cheaper pest control, just add ants
Ants offer a surprisingly effective alternative to synthetic pesticides on crops ranging from cashews to sugar cane, according to a new review of more than 70 scientific studies.

Sometimes ants are pests, marching through our kitchens on an industrious quest for crumbs. But when faced with more serious pests — namely those that destroy crops on which people’s livelihoods depend — we can also use ants to our advantage.
Published in the Journal of Applied Ecology, a new research review suggests ants can control agricultural pests as efficiently as synthetic pesticides, with the bonus of being more cost-effective and generally safer. And since many pesticides pose a danger to helpful wildlife like birds, bees and spiders — not to mention humans — ants might be a key ally in feeding the planet’s booming human population.
The review covers more than 70 scientific studies on dozens of pest species that plague nine crop varieties in Africa, Southeast Asia and Australia. Because ants are organized as “superorganisms” — meaning the colony itself is like an organism, with individual ants acting as “cells” that can move around independently — they are uniquely capable of hunting down pests and then overwhelming them.
“Ants are great hunters and they work cooperatively,” says author Joachim Offenberg, a biologist at Aarhus University in Denmark, in a press release about the research. “When an ant finds its prey, it uses pheromones to summon help from other ants in the nest. By working together, they can subdue even large pests.”
Most studies in the review focused on weaver ants, a tropical genus of tree-dwelling ants that weave ball-shaped nests using leaves and larval silk. Since they live in the canopy of their host trees, near the fruit and flowers that need protection, weaver ants have a natural tendency to control pest populations in orchards.

In one three-year study, Australian cashew growers recorded yields 49 percent higher in trees guarded by weaver ants versus trees treated with synthetic chemicals. But higher yields were only part of the prize: The farmers also got higher-quality cashews from the trees with ants, resulting in a 71 percent higher net income.
Similar results were reported in mango orchards. While mango trees with ants had roughly the same yields as those with synthetic chemicals, the ants were cheaper — and the trees they inhabited grew higher-quality fruit. That led to a 73 percent higher net income compared with pesticide-treated trees. Not all crops had such dramatic results, but studies on more than 50 pests showed that ants can protect crops including cocoa, citrus and palm oil at least as effectively as pesticides.
“Although these are rare cases where the ants were superior to chemicals, many studies show that ants are just as efficient as chemical controls,” Offenberg says. “And of course ant technology is much cheaper than chemical pest control.”
To recruit weaver ants in their orchards, farmers just collect nests from the wild, hang them in plastic bags from tree branches and feed them a sugar solution while they build new nests. Once the ants establish their colony, farmers can help them expand by connecting target trees with aerial walkways made from string or vines.
The ants are mostly self-sufficient from there, needing only some water during the dry season — provided via plastic bottles in the trees — and pruning of non-target trees that host different ant colonies to prevent fights. Farmers can also help their ants by avoiding broad-spectrum insecticide sprays, researchers say.

It’s worth noting that ants can also be detrimental to some plants, such as when they herd sap-feeding insects like aphids and leafhoppers. But if they still fend off fruit-ruining flies and beetles, their net impact may be positive nonetheless. Not only do weaver ants kill pest insects on their trees, but their presence alone is reportedly enough to scare away marauders as large as snakes and fruit bats. And research suggests their urine even contains important plant nutrients.
The use of ants for pest control isn’t new. As early as 300 B.C., Chinese farmers could buy weaver ants in markets to release in their citrus groves, a practice that has faded over time, especially after the advent of chemical pesticides. But it may be coming back, both because ants are cheaper than pesticides and because certified organic produce can fetch higher prices, due to concerns that broad-spectrum pesticides harm more than just pests. Aarhus University is studying the use of weaver ants as pest control in Benin and Tanzania, for example, where the insects could lead to increased export revenue of $120 million and $65 million, respectively.
“To kill the flies with pesticides, you have to make the mango so poisonous that it can kill the maggot,” Aarhus University biologist Mogens Gissel Nielsen told China’s Xinhua news agency in 2010. “But when it is too poisoned for the maggot to eat, it might not be good for us to eat either.”
While the research in Offenberg’s review focused largely on weaver ants, he points out they “share beneficial traits with almost 13,000 other ant species, and are unlikely to be unique in their properties as control agents.” Lots of ants nest in the ground, and while it may be a challenge to relocate them, they too have shown promise in protecting a variety of commercially important crops.
“Weaver ants need a canopy for their nests, so they are limited to plantations and forestry in the tropics,” Offenberg says. “But ground-living ants can be used in crops such as maize and sugar cane. European wood ants are renowned for controlling pests in forestry, and new projects are trying to use wood ants to control winter moths in apple orchards. Ants could even be used to fight plant pathogens because they produce antibiotics to combat diseases in their dense societies.”

As with many of the other fine articles that appear on Mother Nature Network, this report by Russell McLendon has many links to other information sources, too many for me to set up. So if this report ‘speaks’ to you and you want to look up the background information then please go here and read it over on MNN.
Even before I met Jean back in 2007 and came out from England to be with her in 2008 (with Pharaoh), I had learnt that one of the many joys in having a dog was being able to share so much of one’s life with your loving canine companion.
Thus you will not be surprised in the slightest that walking with your dog is another joyous activity. Plus the benefit of living a few more years, as the following article from Mother Nature News illustrates.

The secret to adding 7 years to your life
Hint: Get ready to lace up your sneakers.

It’s easier than you might think to add another seven years to your life. Researchers have found that adding a simple 25-minute walk to your daily routine could give you several more years of healthy living.
Researchers found that participants in their 50s and 60s who took a brisk daily walk that lasted for at least 25 minutes had half the risk of dying from a heart attack than their couch-potato peers. The study, conducted at Saarland University in Germany, evaluated the health of 69 healthy non-smokers, aged between 30 and 60, who were not regular exercisers before the study began.
Participants were asked to complete various types of daily exercise — from simple aerobics to high-intensity interval training to strength training over a six-month period. Meanwhile, researchers took blood samples that allowed them to measure the increase of telomerase activity and the decrease of senescence markers, two indicators of cellular aging found in the blood. Using these measurements, researchers found that daily aerobic exercise triggers the anti-aging process.
Researchers presented their findings at the European Society of Cardiology conference with the suggestion that people add regular exercise to their daily routine to add years to their lives. They also noted that it’s never too late to start. A 70-year-old woman who has never exercised before can still gain tremendous mental and physical health benefits by adding a brisk daily walk to her routine.
Heart disease is the number one killer of men and women in the U.S. According to the Centers for Disease Control and Prevention, more than 600,000 Americans will lose their lives to the disease this year, but exercise could slash that figure in half, bringing more years to millions of Americans.
Do you have your sneakers laced yet?

Want to see Earth’s super predator? Look in the mirror.
Our efficient killing technologies have given rise to the human super predator. Our impacts are as extreme as our behavior, says study.

Extreme human predatory behavior is responsible for widespread wildlife extinctions, shrinking fish sizes and disruptions to global food chains, according to research published in the August 21 edition of the journal Science these are extreme outcomes that non-human predators seldom impose, according to the article.
Lead researcher Chris Darimont is a professor of geography at the University of Victoria. Darimont said:
Our wickedly efficient killing technology, global economic systems and resource management that prioritize short-term benefits to humanity have given rise to the human super predator. Our impacts are as extreme as our behavior and the planet bears the burden of our predatory dominance.

The team’s global analysis indicates that humans typically exploit adult fish populations at 14 times the rate than do marine predators. Humans also hunt and kill large land carnivores such as bears, wolves and lions at nine times the rate that these predatory animals kill each other in the wild.
Researchers noted that in some cases, dwindling species of predatory land carnivores are more aggressively hunted for trophies, due to the premium placed on rare prey.
The result of human activity on wildlife populations is far greater than natural predation. Research suggests that socio-political factors can explain why humans repeatedly overexploit. Technology explains how: Humans use advanced killing tools, cheap fossil fuel, and professional harvesters – like high-volume commercial fishing fleets – to overcome the defensive adaptations of prey.
Humanity also departs fundamentally from predation in nature by targeting adult quarry.Co-author Tom Reimchen is a biology professor at University of Victoria. He said:
Whereas predators primarily target the juveniles or ‘reproductive interest’ of populations, humans draw down the ‘reproductive capital’ by exploiting adult prey.
During four decades of fieldwork on Haida Gwaii, an archipelago on the northern coast of British Columbia, Reimchen looked at how human predators differ from other predators in nature. Reimchen’s predator-prey research revealed that predatory fish and diving birds overwhelmingly killed juvenile forms of freshwater fish. Collectively, 22 predator species took no more than five per cent of the adult fish each year. Nearby, Reimchen observed a stark contrast: fisheries exclusively targeted adult salmon, taking 50 per cent or more of the runs.
The authors conclude with an urgent call to reconsider the concept of “sustainable exploitation” in wildlife and fisheries management. A truly sustainable model, they argue, would mean cultivating cultural, economic and institutional change that places limits on human activities to more closely follow the behavior of natural predators. Darimont said:
We should be protecting our wildlife and marine assets as an investor would in a stock portfolio.
Bottom line: According to research published in the August 21, 2015 edition of Science, extreme human predatory behavior is responsible for widespread wildlife extinctions, shrinking fish sizes and disruptions to global food chains.
Chris Darimont really put his finger on the spot in my opinion when he was quoted,”We should be protecting our wildlife and marine assets as an investor would in a stock portfolio.”
Going to close today’s post by repeating what is presented on the Welcome page of Learning from Dogs, namely:
As man’s companion, protector and helper, history suggests that dogs were critically important in man achieving success as a hunter-gatherer. Dogs ‘teaching’ man to be so successful a hunter enabled evolution, some 20,000 years later, to farming, thence the long journey to modern man. But in the last, say 100 years, that farming spirit has become corrupted to the point where we see the planet’s plant and mineral resources as infinite. Mankind is close to the edge of extinction, literally and spiritually.
Dogs know better, much better! Time again for man to learn from dogs!
With the memory of Hurricane Katrina refreshed in our minds as we acknowledge the recent passing of the tenth anniversary of that ghastly disaster, a link to an item from May, 2013 that was published on Mother Nature Network seems perfect for this place.

Why we turn to dogs when disaster strikes
From aiding search-and-rescue missions to lending a shoulder to cry on, man’s best friend can often be found at the site of tragedy.
By: Laura Moss, May 21, 2013.

Disaster relief is flooding into Moore, Okla., but along with volunteers and supplies, there are dogs.
Some, including the 11 canine disaster search teams trained by the Search Dog Foundation or SDF, are scouring tornado debris for survivors. Others are en route to comfort the devastated city’s residents. Lutheran Church Charities, whose therapy dogs have worked with victims of the Boston bombings and the Newtown, Conn., shootings, is sending six dogs from its Chicago headquarters.
When disaster strikes, man’s best friend is often there, working on the frontlines of rescue efforts, as well as behind the scenes, helping people cope with trauma and loss.
Super sniffers
Experts estimate that one search-and-rescue (SAR) dog can accomplish the work of 20 to 30 human searchers. Because of these unparalleled abilities, the number of trained SAR dogs has been rising across the United States.
Dogs make efficient searchers due to their superior vision, hearing and sense of smell. A dog’s nose is about 100 times more sensitive than a human nose, and SAR dogs are trained to locate human scents amid countless other smells. They track our scents by the 30,000 to 40,000 dead skin cells we drop every minute.
“Dogs aren’t miracle workers, but their noses are so precious,” said SDF founder Wilma Melville. “They can find those people who survived a horrific ordeal.”
Air-scent dogs are trained to work in specific types of terrain. Some search in wilderness settings while others search urban environments, which often can involve scouring collapsed buildings.
Because they must navigate unstable terrain, urban SAR dogs are some of the most highly trained canines. The only national standards for such dogs are the Federal Emergency Management Agency’s certification standards for urban disaster work. Currently, fewer than 100 dog-handler teams in the U.S. have this certification.
In addition to air-scent dogs, there are dogs taught to seek out both skin cells and the smell of human decomposition. During major disasters, such as the 1995 Oklahoma City bombing and the 2001 collapse of the World Trade Center, both air-scent dogs and cadaver dogs were used to search for people.
This caused problems for SAR dogs because they became discouraged when they found only dead bodies. At both Oklahoma City and Ground Zero, handlers hid in rubble so that dogs could occasionally find a living person. The dogs’ desire to elicit a response from a found person may be a result of their training, which involves seeking feedback and rewards, but experts say it could also speak to a deeper connection with humans.
Man’s best friend
When disasters occur, dogs do much more than just aid search-and-rescue missions. They’re often there to provide a source of comfort for us in ways that only an animal can.
In an interview with American Thinker, Debra Tosch, executive director of SDF, explained how her SAR dog Abby was able to console a firefighter at Ground Zero. “When someone was found, work would stop, and I watched as the tears rolled down the firefighters’ faces. I remember one firefighter who hugged Abby and buried his face in her neck after just finding out a fellow firefighter was found,” she said.
Research show that petting dogs can lower anxiety, regulate breathing and decrease blood pressure, and a Japanese study found that simply looking at a dog can increase oxytocin levels. Oxytocin is a chemical released by the pituitary gland that’s associated with human bonding and affection.
But while the firefighter may have found comfort in Abby’s presence, was the dog able to empathize? Research says it’s very likely.
A 2012 study at Portugal’s University of Porto found that dogs yawn even when they hear only the sound of a person yawning, providing strong evidence that dogs are able to empathize with us.
And a study at the University of London Goldsmiths College found that dogs comforted people — both their owners and strangers — when the person pretended to cry.
“I think there is good reason to suspect dogs would be more sensitive to human emotion than other species,” Custance told Discovery News. “We have domesticated dogs over a long period of time. We have selectively bred them to act as our companions. Thus, dogs that responded sensitively to our emotional cues may have been the individuals that we would be more likely to keep as pets and breed from.”
ooOOoo
Time and time again, the facts support what the vast majority of those who care for and love dogs truly know: the bond between dog and human is the most special that there has ever been between an animal and mankind.
Say the word ‘dog’ to me and my immediate thought would be of the domesticated animal, as I’m sure would be the first thought of thousands of others.
But our wonderful doggie companions came from the wild and in some countries wild dogs still are widely found. There was an article on the Mokolodi Nature Reserve blogsite in November, 2009 specifically about wild dogs, that included the following picture:
Wild hunting dogs drinking.
All of which is a wonderful reminder that wilderness is a critical and essential element in the overall health of our planet, and by extension, of ourselves.
The academic blogsite The Conversation yesterday published an article by William Lynn who is a Research Scientist in Ethics and Public Policy at Clark University. It proposes a wonderful way of keeping our populations of wild animals healthy and vibrant through rewilding. It is republished here within the terms of The Conversation.

Setting aside half the Earth for ‘rewilding’: the ethical dimension
August 26, 2015 5.50am EDT

The famous biologist and naturalist would do this by establishing huge biodiversity parks to protect, restore and connect habitats at a continental scale. Local people would be integrated into these parks as environmental educators, managers and rangers – a model drawn from existing large-scale conservation projects such as Area de Conservación Guanacaste (ACG) in northwestern Costa Rica.
The backdrop for this discussion is that we are in the sixth great extinction event in earth’s history. More species are being lost today than at any time since the end of the dinosaurs. There is no mystery as to why this is happening: it is a direct result of human depredations, habitat destruction, overpopulation, resource depletion, urban sprawl and climate change.
Wilson is one of the world’s premier natural scientists – an expert on ants, the father of island biogeography, apostle of the notion that humans share a bond with other species (biophilia) and a herald about the danger posed by extinction. On these and other matters he is also an eloquent writer, having written numerous books on biodiversity, science, and society. So when Wilson started to talk about half-Earth several years ago, people started to listen.
As a scholar of ethics and public policy with an interest in animals and the environment, I have been following the discussion of half-Earth for some time. I like the idea and think it is feasible. Yet it suffers from a major blind spot: a human-centric view on the value of life. Wilson’s entry into this debate, and his seeming evolution on matters of ethics, is an invitation to explore how people ought to live with each other, other animals and the natural world, particularly if vast tracts are set aside for wildlife.
The ethics of Wilson’s volte-face
I heard Wilson speak for the first time in Washington, DC in the early 2000s. At that talk, Wilson was resigned to the inevitable loss of much of the world’s biodiversity. So he advocated a global biodiversity survey that would sample and store the world’s biotic heritage. In this way, we might still benefit from biodiversity’s genetic information in terms of biomedical research, and perhaps, someday, revive an extinct species or two.
Not a bad idea in and of itself. Still, it was a drearily fatalistic speech, and one entirely devoid of any sense of moral responsibility to the world of nonhuman animals and nature.
What is striking about Wilson’s argument for half-Earth is not the apparent about-face from cataloging biodiversity to restoring it. It is the moral dimension he attaches to it. In several interviews, he references the need for humanity to develop an ethic that cares about planetary life, and does not place the wants and needs of a single species (Homo sapiens sapiens) above the well-being of all other species.

To my ear, this sounds great, but I am not exactly sure how far it goes. In the past, Wilson’s discussions of conservation ethics appear to me clearly anthropocentric. They espouse the notion that we are exceptional creatures at the apex of evolution, the sole species that has intrinsic value in and of ourselves, and thus we are to be privileged above all other species.
In this view, we care about nature and biodiversity only because we care about ourselves. Nature is useful for us in the sense of resources and ecological services, but it has no value in and of itself. In ethics talk, people have intrinsic value while nature’s only value is what it can do for people – extrinsic value.
For example, in his 1993 book The Biophilia Hypothesis, Wilson argues for “the necessity of a robust and richly textured anthropocentric ethics apart from the issues of rights [for other animals or ecosystems] – one based on the hereditary needs of our own species. In addition to the well-documented utilitarian potential of wild species, the diversity of life has immense aesthetic and spiritual value.”
The passage indicates Wilson’s long-held view that biodiversity is important because of what it does for humanity, including the resources, beauty and spirituality people find in nature. It sidesteps questions of whether animals and the rest of nature have intrinsic value apart from human use.
His evolving position, as reflected in the half-Earth proposal, seems much more in tune with what ethicist call non-anthropocentrism – that humanity is simply one marvelous but no more special outcome of evolution; that other beings, species and/or ecosystems also have intrinsic value; and that there is no reason to automatically privilege us over the rest of life.
What kind of a species are we that we treat the rest of life so cheaply? There are those who think that’s the destiny of Earth: we arrived, we’re humanizing the Earth, and it will be the destiny of Earth for us to wipe humans out and most of the rest of biodiversity. But I think the great majority of thoughtful people consider that a morally wrong position to take, and a very dangerous one.
The non-anthropocentric view does not deny that biodiversity and nature provide material, aesthetic and spiritual “resources.” Rather, it holds there is something more – that the community of life has value independent of the resources it provides humanity. Non-anthropocentric ethics requires, therefore, a more caring approach to people’s impact on the planet. Whether Wilson is really leaving anthropocentrism behind, time will tell. But for my part, I at least welcome his opening up possibilities to discuss less prejudicial views of animals and the rest of nature.
The 50% solution
It is interesting to note that half-Earth is not a new idea. In North America, the half-Earth concept first arose in the 1990s as a discussion about wilderness in the deep ecology movement. Various nonprofits that arose out of that movement continued to develop the idea, in particular the Wildlands Network, the Rewilding Institute and the Wild Foundation.
These organizations use a mix of conservation science, education and public policy initiatives to promote protecting and restoring continental-scale habitats and corridors, all with an eye to preserving the native flora and fauna of North America. One example is ongoing work to connect the Yellowstone to Yukon ecosystems along the spine of the Rocky Mountains.
Take it up a notch? The British Columbia Ministry of Transportation recently started to add signs warning motorists when they are likely to encounter wildlife. British Columbia Ministry of Transportation, CC BY-NC-ND
When I was a graduate student, the term half-Earth had not yet been used, but the idea was in the air. My classmates and I referred to it as the “50% solution.” We chose this term because of the work of Reed Noss and Allen Cooperrider’s 1994 book, Savings Nature’s Legacy. Amongst other things, the book documents that, depending on the species and ecosystems in question, approximately 30% to 70% of the original habitats of the Earth would be necessary to sustain our planet’s biodiversity. So splitting the difference, we discussed the 50% solution to describe this need.
This leads directly into my third point. The engagement of Wilson and others with the idea of half-Earth and rewilding presupposes but does not fully articulate the need for an urban vision, one where cities are ecological, sustainable and resilient. Indeed, Wilson has yet to spell out what we do with the people and infrastructure that are not devoted to maintaining and teaching about his proposed biodiversity parks. This is not a criticism, but an urgent question for ongoing and creative thinking.
Humans are urbanizing like never before. Today, the majority of people live in cities, and by the end of the 21st century, over 90% of people will live in a metropolitan area. If we are to meet the compelling needs of human beings, we have to remake cities into sustainable and resilient “humanitats” that produce a good life.
Such a good life is not to be measured in simple gross domestic product or consumption, but rather in well-being – freedom, true equality, housing, health, education, recreation, meaningful work, community, sustainable energy, urban farming, green infrastructure, open space in the form of parks and refuges, contact with companion and wild animals, and a culture that values and respects the natural world.
To do all this in the context of saving half the Earth for its own sake is a tall order. Yet it is a challenge that we are up to if we have the will and ethical vision to value and coexist in a more-than-human world.
ooOOoo
I am sure many will agree that this is a very interesting idea and one that I hope is eventually adopted. For the sake of all our wild animals, including our dogs.
“Thousands have lived without love, not one without water.”
That sub-heading is a quotation from W. H. Auden and while directed at man it applies to all animal life including our beloved dogs.
The drought that California is experiencing is world-wide news but, possibly, the fact that this drought extends to much of the Pacific West Coast on the United States is not as widely known.
Here in Merlin, Southern Oregon, our own ‘all-year’ creek, Bummer Creek, that flows through our property has been dry for about two weeks. Our grass fields are parched brown and many of the trees are signalling a shortage of water. And let’s not even think about the underground aquifer that supplies our drinking water.
All of which makes a sombre introduction to a recent essay over on TomDispatch, republished here with the very kind permission of Tom Engelhardt. (But see my note at the end of the essay.)

Tomgram: William deBuys, Entering the Mega-Drought Era in America
Posted by William deBuys at 4:17pm, August 16, 2015.
The other day here in New England it was chilly, rainy, and stormy and I complained. Where was the sun? The warmth? The summer? I happened to be with someone I know from California and he shook his head and said, “It’s fine with me. I like it rainy. I haven’t seen much rain in a while.” It was a little reminder of how insular we can be. California, after all, is in the fourth year of a fearsome drought that has turned much of the North American West, from Alaska and Canada to the Mexican border, into a tinderbox. Reservoirs are low, rivers quite literally drying up, and the West is burning. In rural northern California, where the fires seem to be least under control, the Rocky Fire has already burned 109 square miles and destroyed 43 homes, while the Jerusalem Fire, which recently broke out nearby, quickly ate up almost 19 square miles while doubling in size and sent local residents fleeing, some for the second time in recent weeks.
Fires have doubled in these drought years in California. The fire season, once mainly an autumnal affair, now seems to be just about any day of the year. (This isn’t, by the way, just a California phenomenon. The latest study indicates that fire season is extending globally, with a growth spurt of 18.7% in the last few decades.) In fact, fire stats for the U.S. generally and the West in particular are worsening in the twenty-first century, and this year looks to be quite a blazing affair, with six million acres already burned across the region and part of the summer still to go. And here’s the thing: though “I’m not a scientist,” it’s pretty hard at this point not to notice — though most Republican candidates for president seem unfazed — that this planet is heating up, that today’s droughts, bad as they are, will be put in the shade by the predicted mega-droughts of tomorrow, and that the problem of water in the American West is only going to deepen — or do I mean grow shallower? TomDispatch regular William deBuys, an expert on water in that region and author of A Great Aridness: Climate Change and the Future of the American Southwest, has already written dramatically of a future “exodus from Phoenix.” For clues to what we will all experience sooner or later, he now turns to California, that bellwether state in which, as he writes, the future always seems to play itself out first.

California First
As Both Climate Victim and Responder, the National Style-Setter Leads the Way
By William deBuys
Long ago, I lived in a cheap flat in San Francisco and worked as the lone straight man in a gay construction company. Strangely enough, the drought now strangling California brings back memories of those days. It was the 1970s. Our company specialized in restoring the Victorian “gingerbread” to the facades of the city’s townhouses, and I got pretty good at installing cornices, gable brackets, and window hoods, working high above the street.
What I remember most, though, is the way my co-workers delighted in scandalizing me on Monday mornings with accounts of their weekend exploits.
We were all so innocent back then. We had no idea of the suffering that lay ahead or of the grievous epidemic already latent in the bodies of legions of gay men like my friends, an epidemic that would afflict so many outside the gay community but was especially terrible within it.
It’s unlikely that many of those guys are alive today. HIV was already in the population, although AIDS had yet to be detected or named, and no one had heard of “safe sex,” let alone practiced it. When the epidemic broke out, it was nowhere worse than in trendsetting San Francisco.
By then I had returned to New Mexico, having traded my hammer for a typewriter. When I announced my intention to leave California, the guys all said the same thing. “Don’t go back there,” they protested. “You’ll just have to go through all of this again!”
All of this required no translation. It meant the particular newness of life in that state, which was always sure to spread eastward, as Californian styles, attitudes, problems, tastes, and fads had been spreading to the rest of the country almost since the days of the Gold Rush.
Hippies, flower power, bikers, and cults. The movies we see and the music we listen to. The slang we pick up (I mean like, what a bummer, dude). Wine bars and fern bars, hot tubs and tanning booths, liposuction and boob jobs. The theft of rivers (Forget it, Jake. It’s Chinatown) and the theft of baseball teams (Brooklyn still mourns). Gay rights, car culture, and the Reagan Revolution. Scientology, mega-churches, Buddhist chic, and exercise videos. If they didn’t actually start in California, they got big and came to national attention there. Without the innovations of Silicon Valley, would you recognize your mobile phone or computer? Would you recognize yourself?
It’s the same with climate change. California in the Great Drought is once again Exhibit A, a living diorama of how the future is going to look for a lot of us.
And the present moment — right now in 2015 — reminds me of San Francisco as the AIDS epidemic broke out. Back then we had no idea how bad things were going to get, and that is likely to be true now, as well. As usual, California is giving us a preview of our world to come.
The Arrival of the Bone-Dry New Normal
On the U.S. Drought Monitor’s current map, a large purple bruise spreads across the core of California, covering almost half the state. Purple indicates “exceptional drought,” the direst category, the one that tops both “severe” and “extreme.” If you combine all three, 95% of the state is covered. In other words, California is hurting.
Admittedly, conditions are better than at this time last year when 100% of the state was at least “severe.” Recent summer rains have somewhat dulled the edge of the drought, now in its fourth year. Full recovery, however, would require about a foot of rain statewide between now and January, a veritable deluge for places like Fresno, which in good times only get that much rain in a full year.
To be clear, the current drought may not have been caused by climate change. After all, California has a long history of periodic fierce droughts that arise from entirely natural causes, some of them lasting a decade or more. Even so, at a minimum climate change remains a potent factor in the present disaster. The fundamental difference between California’s current desiccation and its historical antecedents is that present conditions are hotter thanks to climate change, and hotter means drier since evaporation increases with temperature. Moreover, the relationship between the two is non-linear: as temperature creeps up, evaporation gallops. Bottom line: the droughts of the future will be much more brutal — and destructive — than those of the past.
California is already on average about 1.7° Fahrenheit hotter than a century ago, and its rate of warming is expected to triple in the century ahead. The evaporative response to this increase will powerfully amplify future droughts in unprecedented ways, no matter their causes.
Throughout the state, draconian cutbacks in water use remain in force. Some agricultural districts are receiving 0% of the federally controlled irrigation water they received in past years, while state water deliveries are running at about 15% of normal.
Meanwhile, a staggering 5,200 wildfires have burned in the state’s forests and chaparral country this year, although timely rains everywhere but in the northern parts of California and the rapid responses of a beefed-up army of firefighters limited the burning to less acreage than last year — at least until recently. The blow-up of the Rocky Fire, north of San Francisco, in the early days of August — it burned through 20,000 acres in just a few hours — may change that mildly promising statistic. And the fire season still has months to go.
So how is this a trendsetter, a harbinger for lands to the east? California’s drought is deep and long — we don’t yet know how long — and the very long-term forecast for an immense portion of western North America, stretching from California to Texas and north to South Dakota, is for a future of the same, only worse. Here is the unvarnished version of that future (on which an impressive number of climate models appear to agree) as expressed in a paper that appeared in Science Advances last February: “The mean state of drought in the late 21st century over the Central Plains and Southwest will likely exceed even the most severe mega-drought periods of the Medieval era in both high and moderate emissions scenarios, representing an unprecedented fundamental shift with respect to the last millennium.”
Let’s unpack that a little bit: principal author Benjamin Cook of NASA and his colleagues from Columbia and Cornell universities are saying that climate change will bring to the continent a “new normal” more brutally dry than even the multiple-decades-long droughts that caused the Native American societies of Chaco Canyon and Mesa Verde to collapse. This, they add, is now expected to happen even if greenhouse gas emissions are significantly lowered in the decades to come. The impact of such droughts, they conclude, will exceed the bounds of anything known in the history of the continent or in its scientifically reconstructed pre-history.
In other words, the California drought of recent years offers only a foretaste of what is to come. Incidentally, Cook, et al. are by no means outliers in the literature of climate prediction. Other important studies with similar forecasts support a steadily broadening consensus on the subject.
And North American droughts will have to compete for attention with countless other climate change impacts, especially the hundreds of millions of refugees worldwide who will be put into motion by rising sea levels and other forces that will render their present homes unlivable.
A User’s Guide to Climate Change
If California points the way to dry times ahead, it also gives us an early glimpse of how a responsible society will try to live with and adjust to a warmer future. The state has imposed stringent new limits on water use and is actively enforcing them, and in general, individual consumers have responded positively to the new requirements, in some cases even exceeding mandated conservation goals.
In a similar spirit, the state has augmented its wildland fire-fighting capacity to good effect, even as the fire danger has approached levels never before seen.
Perhaps most impressively the state has adopted its own pioneering cap-and-trade program aimed at rolling back total greenhouse gas emissions to 1990 levels. Under cap-and-trade, carbon polluters have to obtain permits to continue their emissions, and only a finite number of such permits are made available. A coal-burning power plant or a refinery has to buy its permit from the state or from another company that already has one. This way, a ceiling is established for total greenhouse gases emitted by the most energy-intensive sectors of the economy.
Although the jury may still be out on how well the program meets its goals, there is no debating its positive impact on the state treasury. In the fiscal year just begun, the auction of permits under California’s cap-and-trade program will net approximately $2.2 billion, a windfall that will be spent on mass transit, affordable housing, and a range of climate-adaptation programs. And by the way, the warnings of nay-sayers and climate deniers that cap-and-trade would prove a drag on the economy have proved groundless.
In a manner similar to the U.N.’s prestigious Intergovernmental Panel on Climate Change, California now publishes an assessment every three years of both its vulnerability to climate change and the steps it plans to take to mitigate or adapt to its effects. The report is a model of its kind and draws on copious California-specific scientific research, some of which is funded by the state.
You might think California’s neighbors would follow suit, and eventually, as with most things Californian, they undoubtedly will. If President Obama’s just-announced “Clean Power Plan” withstands the expected court challenges, it will prove a powerful spur in that direction as it mandates state-by-state reductions in power plant carbon emissions that will, in the end, drive them 32% below 2005 levels. Many states will undoubtedly have to adopt cap-and-trade systems in order to comply. As they set about devising their own programs, where do you think they will look for a workable example? You guessed it: California.
An “Island” Again, or Nearly So
In the seventeenth century, Spanish cartographers thought California was an island separated from the rest of North America by the legendary Straits of Anian. In some ways, nothing has changed. In late July, while California Governor Jerry Brown was at the Vatican joining Pope Francis in calling for urgent global action to combat climate change, his opposite numbers across the putative straits continued to assume the posture of startled ostriches.
Doug Ducey, the Republican governor of Arizona, admits that the climate may indeed be changing but doubts that humans play a causal role in it. Susana Martinez of New Mexico, also a Republican, continues to insist that climate science is inconclusive, while former governor of Texas and current presidential candidate Rick Perry adamantly remains “not a scientist,” although he knew enough to inform us in his 2012 campaign screed Fed Up that climate change science is “a contrived phony mess.”
In general, when it comes to climate change, the leadership of statehouses across the country remains as troglodytic as the House of Representatives. Only in Hawaii, Oregon and Washington on the West Coast, Minnesota in the Midwest, and a handful of Northeastern states will governors even acknowledge the importance of acting to curb climate change as well as adapt to it.
This year, the deniers may get a boost from an unlikely source. Warm surface waters seem to be brewing something special in the Pacific Ocean. Says one researcher, “The El Niño event currently ongoing in the eastern and central Pacific is strengthening. The only question is whether it will be just a significant event, or a huge one.”
El Niño draws the winter Pacific storm track southward, bringing precipitation to southern California, Arizona, and points eastward. If the southern tier of states has a wet winter, the Republican rain-dancers will feel confirmed in their official doubt and denialism, much as a broken clock is right at least twice a day.
Occasional El Niños, however, will not avert the long-term new normal for California and much of the West. As that state is showing, adaptation will soften some of the blows, and possibly, if we act soon enough and strongly enough, we may manage to cap the overall changes at some still livable level. The jury will be out on that for quite some time.
Meanwhile, as in pre-AIDS San Francisco, we are all still in a state of at least semi-innocence. Maybe we can imagine in an intellectual way what it might be like to lose the forests across half of the continent, but can any of us conjure the feeling of how that would be?
After many missteps and halting starts, the medical and public health establishments finally came to the assistance of the victims of AIDS. As difficult as that was, it was easy compared to the remedies climate change will demand. And for much of the damage there will be no remedy. Get ready.

This is a TED video presented by Will Marshall. A quick web search reveals that Will Marshall is:
Co-founder & CEO of Planet Labs.
Planet Labs is helping share near-real-time images of our planet, from a constellation of earth-observing satellites.
In his Twitter bio, William Marshall calls himself a “quantum physicist cum space scientist in search of world peace and harmony.” And when you hear about his job, it falls into place: he and his cofounders at Planet Labs want to show the earth what it looks like, almost real time, via a new network of compact, capable satellites. They hope that up-to-date images will inform future humanitarian and commercial projects all over our planet; it will enable people to make decisions that enable us to take care of our dearest spaceship, spaceship earth.
Before co-founding Planet Labs, Marshall was a scientist at NASA/USRA, where he helped to formulate the Small Spacecraft Office at NASA Ames Research Center. He worked on lunar orbiter mission LADEE, lunar impactor mission LCROSS and the groundbreaking PhoneSat project, building satellites out of consumer parts.
It was only a couple of mouse clicks to find the website for Planet Labs.
All of which is my way of introducing the TED video but not before thanking next door neighbour Larry Little who emailed me the link to the video.
Published on Nov 18, 2014
Satellite imaging has revolutionized our knowledge of the Earth, with detailed images of nearly every street corner readily available online. But Planet Labs’ Will Marshall says we can do better and go faster — by getting smaller. He introduces his tiny satellites — no bigger than 10 by 10 by 30 centimeters — that, when launched in a cluster, provide high-res images of the entire planet, updated daily.

In the last twenty-four hours, Learning from Dogs has attracted a new follower. As always, I went across to this person’s blogsite and left a ‘thank you’ note. I loved what I saw because the blogsite was called Wolves of Douglas County Wisconsin authored by Rachel Tilseth. Better than that, there were a number of posts that I know LfD readers would enjoy very much.

Compassionate Conservation
When I think of compassionate conservation several well known conservationists, scientists, and psychologists come to mind. On a scale one to ten Dr. Jane Goodall, Joy Adamson, Bill Travers and Virginia McKenna, and Marc Bekoff Ph.D all rate in the top ten for their compassionate ideals and work regarding wild animals. I believe that it is wrong for humankind to kill off one species to save another because it is not acting in the best interests of wild animals and the ecosystems they support.
In a recent Facebook post on Todd Wilkinson’s timeline I was alerted to a column by Dr. Marc Bekoff on the subject of ‘compassionate conservation’ and decided to post Beckoff’s thought provoking article on my blog.
The broad and interdisciplinary field of conservation biology(link is external) has received a good deal of attention in the past two weeks that has stimulated researchers and others to weigh in on what sorts of human-animal interactions are permissible as we try to save nonhuman animals (animals) and their homes. For example, some of the challenging questions that arise are: Should we kill in the name of conservation? Is it okay to trade off the lives of animals of one species for the good of their own or other species? Is seeking the “most humane” way of killing animals the only way to move forward? Is it possible to stop the killing of other animals and factor compassion that centers on the lives of individuals into our decisions? Should we try a “hands off” policy to see if it works where it’s clear our interference, despite our best intentions, has not solved the problems at hand? How do we factor in the interests of other animals and humans as we deal with the numerous — and growing — challenging and frustrating conflicts at hand? The field of anthrozoology (link is external) focuses on these and other questions.
Clearly, there are going to be differences among the people who are trying to save other animals and their homes and also take into account the interests of humans. And, this is what makes the field of conservation biology so exciting, for we are the only animals who are able to do what needs to be done to reverse the rather dismal and depressing situations in which humans and other animals find themselves in conflict. It goes without saying that the major problem is that there are too many humans and if we don’t stop making more of us it’s going to be a long and hard battle to right the wrongs for which we are responsible. And, given all of the information that is currently available, I like to call attention to a quote from William Wilberforce sent to me by Sadie Parr of Wolf Awareness(link is external), “You may choose to look the other way but you can never say again that you did not know. (link is external)”
Compassionate conservation comes of age
A recent meeting that centered on the rapidly growing international field called compassionate conservation (link is external) brought people together from all over the world, all of whom are trying to reduce or eliminate human-animal conflict. The conference was sponsored and coordinated by the Born Free Foundation (link is external) and the Centre for Compassionate Conservation(link is external) at the University of Technology, Sydney and hosted by the Animal Welfare Program(link is external) at the University of British Columbia (for more on compassionate conservation please click here, here (link is external), and here (link is external)). A most exciting part of the meetings was the presence of numerous students and young researchers. And, also very stimulating, were the obvious differences of opinion — the expected shades of gray — in what is possible and what methods are permissible as we try to deal with rampant and growing global human-animal conflicts. Some people argued that in the “real world” the “most humane” ways of killing are the only ways forward, whereas others argued that compassionate conservation is not about the “most humane” way of killing, but rather centers on stopping the killing because it is unethical and in many instances it really hasn’t worked. For them, individual animals are the focus of concern and the guide for compassionate conservation and “First do no harm (link is external)” means not harming or killing other animals “in the name of conservation.”
There also was very valuable discussion of the words people use to refer to the killing of otherwise healthy animals “in the name of conservation,” with the recognition that it is not euthanasia, or mercy-killing, but rather “zoothanasia” when it’s done in zoos or slaughter when done in other situations (please see “Animal ‘Euthanasia’ Is Often Slaughter: Consider Kangaroos“). Also of interest was the use of the word “pests” to refer to animals who are causing problems. Many agreed that it’s humans who are the pests, but because we can dominate and control other animals, they pay the price for just doing what comes naturally for them but is bothersome for us.
Clearly, there were many valuable discussions, and the abstracts of the broad array of papers that were presented can be seen here (link is external). They are a goldmine of information on the broad topics that were covered, the numerous different species discussed, and anthrozoologists should them to be indispensable for future studies of human-animal relationships. We learned that many wild animals really aren’t free (Yolanda Pretorius of the Centre for Wildlife Management at the University of Pretoria told us that elephants in South Africa are fenced and can’t migrate) and that “methods to assess the well-being of elephants are not included as a requirement for developing an elephant management plan.” Moles are ruthlessly killed in the UK because they destroy gardens and in many locations geese are killed because they poop on golf courses. We take away the geese’s habitats and then we kill them because they have nowhere else to go.
We also learned in a paper by MarÍa Fàbregas and G. M. Koehler of Save China’s Tigers(link is external) that in order to reintroduce critically endangered captive South China tigers back to restored protected areas within their historic range in China, they are allowed to practice killing ungulates. Many people were rather concerned with this practice, and it reminded me of breeding golden hamsters to allow endangered black-footed ferrets to practice killing them before being released into wild habitat. For many, these sorts of trade-offs are unacceptable.
In another project that was the focus of discussion, almost 900 wolves and other non-target animals were killed in Alberta, Canada (please also see and and), to try to save woodland caribou (it didn’t work) and not only were families broken up but there also are trans-generational effects. Simply put, far too many other animals are harmed or killed because we move into their homes and they have nowhere else to go and thus, they, innocent victims, become the “problems.” It’s a no-win situation for millions of other animals and we need to do much better so the killing stops.
Compassionate conservation meets Cecil the slain lion
It was also rather timely, and of course incredibly sad, that news about the thoroughly unnecessary killing of Cecil the lion(link is external) by Walter Palmer (please also see the numerous articles listed here (link is external) and Jennifer Jacquet’s “The Shaming of Walter Palmer (link is external)“) was making world-wide headlines as the meeting got under way. A few of us received requests for interviews the first morning of the meeting and Cecil was the topic of conversation at a number of talks and also at the coffee breaks, as was Marius, the young giraffe who was mercilessly killed at the Copenhagen Zoo in February 2014, because he didn’t fit into the zoo’s breeding program. Marius us a classic case of an animal who was zoothanized, not euthanized, as claimed by zoo administrators.
Many people are interested in the status and fate of African lions and as I was writing this essay I came across a review of a book called Lions in the Balance: Man-Eaters, Manes, and Men with Guns(link is external) by world renowned lion researcher Dr. Craig Packer(link is external) (the Kindle edition can be found here(link is external)). In the review by Iris Barber(link is external) called “Lions in the Balance: Can hunting save the kings of the jungle?” we learn that Dr. Packer argues, “‘Lions need trophy-hunting just as much as trophy-hunting needs lions.’ His plan: kill only male lions over the age of 6, so cubs aren’t killed by a lion mating with their mother who seeks to safeguard his own progeny. This is a fresh approach to conservation, where hunting is essential to survival.”
While numerous compassionate conservationists would argue against killing lions, when experts like Dr. Packer speaks, it’s highly worthwhile to listen carefully because it makes clear just how complex the issues are. As the book’s description notes, “Packer is sure to infuriate millionaires, politicians, aid agencies, and conservationists alike as he minces no words about the problems he encounters. But with a narrative stretching from far flung parts of Africa to the corridors of power in Washington, DC, and marked by Packer’s signature humor and incredible candor, Lions in the Balance is a tale of courage against impossible odds, a masterly blend of science, adventure, and storytelling, and an urgent call to action that will captivate a new generation of readers.”
Putting an end to dancing bears: All stakeholders count
Another tenet of compassionate conservation is that all stakeholders count, human and nonhuman. Of course, this is very challenging because various animals kill or harm humans or kill or harm animals on whom the livelihoods of humans and their communities depend. In an earlier essay I wrote about two projects in India that stress peaceful coexistence between humans and nonhumans who harm and kill the humans and destroy their businesses. Another excellent example of a project that took into account the interests of humans and nonhumans centered on putting an end to the use of dancing bears, discussed by Kartick Satyanarayan and Geeta Seshamani of the organization Wildlife SOS, India (link is external). The abstract for their talk reads as follows:
“Wildlife SOS spearheaded a conservation success story in India by resolving the barbaric dancing bear practice in which sloth bear cubs were poached from the wild, brutally trained in inhumane ways and spent their short tragic lives at the end of a four foot rope dragged through towns and villages to earn for the indigent, nomadic community called the Kalandars. Wildlife SOS’s initiative was to both rehabilitate the sloth bears held in captivity and the Kalandars themselves in alternative livelihoods. This in turn made a huge difference to the sloth bear population in the wild helping in its conservation.
“Compassionate Conservation and sustainability of wildlife and forests was the focus of the program which is still ongoing. Wildlife SOS also works with human-animal conflict situations similarly aiming for compassionate conservation and rehabilitation measures which educate the stakeholders, such as the villagers or dwellers around a forested area, in avoidance behavior.
“The education awareness programs are run in Maharashtra where the conflict species is the leopard and in Kashmir where the conflict species is the black bear and in Delhi and Agra the program deals with the rhesus macaque which seems to be the species humans have declared war on. Attempts at resolution involve creating safe spaces for the animals (rehabilitation centres) teaching people behaviours which do not lead to confrontation with the animals in question (awareness and education) but most importantly to inculcate a feeling for the animals in question emphasizing adjustment and acceptance of the existence of wildlife close to our human habitations. Our work with captive elephants is yet another conservation attempt at bringing down an ancient Indian traditional bastion that emphasizes training elephants using pain, fear and physical abuse by replacing it with compassion.
“Our training school – the kindness school provide straining to elephant keepers on modern and humane elephant management systems, compassionate handling, replacing negative management with positive reinforcement. However conservation also demands use of the law so the Wildlife SOS Anti-Poaching enforcement unit works to gatherintelligence on wildlife traffickers and smugglers and enforces the law working in partnership with the Indian Government.
“Compassionate conservation is the key to the future ahead of us.”
Another wonderful project in which human and nonhuman interests were taken into account and satisfied was concerned with how to deal non-lethally with “problem” raccoons at a fast food restaurant in Vancouver. Dr. Sara Dubois, who works with theBritish Columbia SPCA (link is external), outlined various strategies for coming to terms with urban “pests.” She noted, “The overall goal of developing humane standards for nuisance wildlife control is to create an educational and enforcement tool, setting a higher bar for control measures, whether they are done for conservation or nuisance purposes.”
The coming of age of compassionate conservation: It’s a “sad bad” if killing is the only viable option for “peaceful” coexistence
The field of compassionate conservation is slowly coming of age and it’s essential that all opinions come to the table to be discussed. Ethicist Bill Lynn, who supported the experimental humane killing of a few thousand barred owls to try to save endangered snowy owls, called this practice a “sad good.” While it may be a “sad good” for the snowy owls, it’s surely not for the slaughtered barred owls. I would call it a “sad bad” for the barred owls and many other animals if killing remains the only option. A “sad good” is a very slippery slope that sets a lamentable precedent for opening the door for the more widespread “experimental killing” of barred owls and other species just to see if it works.
Compassionate conservation requires a large change in heart and practices, and like any other revolutionary paradigm shift it will take time. Many hope that this most needed paradigm shift in conservation biology that entails stopping the killing “in the name of conservation” will endure its growing pains as more and more researchers and others realize that killing is not the answer. I hope those who see the “real world” as mandating killing will change their minds and hearts. Future and young researchers are critical to the development and implementation of compassionate conservation, as are those careerconservation officers, zoo administrators, and researchers who come to realize that using “the most humane killing” is not what compassionate conservation is all about. I like to imagine a world where killing is no longer part of the conservationist’s toolkit. The welfarist calculus patronizes other animals and when push comes to shove, or often when it’s merely convenient, the nonhumans suffer and are killed when it’s determined that the benefits to humans outweigh the costs to the animals.
It’s time to put away the guns, the traps, the snares, the poisons, and other “weapons of mass destruction” (as a few attendees called them) and figure out how to live in peaceful coexistence with the fascinating animals with whom we’re supposed to share our most magnificent planet. There does not have to be blood. I dedicated my talk to Cecil the lion and also to Bryce Casavant, a most courageous conservation officer who refused to kill two black bear cubs (link is external) near Port Hardy on northern Vancouver Island and was suspended because he said “no.” More people simply have to say “no” to killing other animals. We need to stop the violence and recognize that “The world becomes what we teach (link is external).” Compassion begets compassion and violence begets violence. By rewilding our hearts (link is external) and by becoming re-enchanted and reconnecting with nature I like to think that the killing will come to an end, slow as it may be.
If some people argue the killing cannot stop, it will not stop. It saddens me to think that we’ve gotten to the point where for some, killing is the only viable option for peaceful coexistence. Shame on us. As Kartick Satyanarayan and Geeta Seshamani concluded, “Compassionate conservation is the key to the future ahead of us.” I couldn’t agree more. We need to leave our comfort zones and think and act “outside of the box.”
The next meeting that will focus on compassionate conservation is slated for 2017 in Sydney, Australia. I often say that compassionate conservation is a wonderful meeting place for people who would otherwise not, but should, meet. This was so in Vancouver and I anticipate this will be the case in Sydney. Please stay tuned for more information on this future gathering and the exciting, challenging, and forward-looking field of compassionate conservation in general.
Note: I just learned of an essay titled “Mutant Animals Bred to be Brutally Killed by Hunters(link is external)” in which the person offering up these freaks outlandishly claims, “Conservation is a by-product of what I do.”
Marc Bekoff’s latest books are Jasper’s story: Saving moon bears (with Jill Robinson), Ignoring nature no more: The case for compassionate conservation, Why dogs hump and bees get depressed, and Rewilding our hearts: Building pathways of compassion and coexistence.

Yes Paul, I too recognise the value in understanding the neural substrates involved, regardless of what may in any case be reliably inferred and readily apparent in behavioural evidence. The social intelligence of the dog seems remarkably advanced of course, and so naturally provides a rich source for such research. Having said that, I am struck by the amount of academic funding that goes into confirming what is already self-evident, and wonder if the apportioning of funds is done quite as effectively as it could be. Much is determined by commercial interests of course.
“Much is determined by commercial interests …”
I have been a resident of the United States since April 2011. There has been much to take in and embrace at so many levels. However, one of the things that has seemed very foreign to my eyes was the extent of the obesity seen almost everywhere that one is out and about. At first it seemed more of an American issue, but over the last few years watching news items from the UK and seeing other general items on the internet from ‘the old country’ I came to realise that countries both ‘sides of the pond’ are grappling with what could be fairly described as an epidemic.
Yesterday, George Monbiot published an essay called Slim Chance. As with so many of Mr. Monbiot’s essays this one highlights issues that I am sure are not widely appreciated. It is republished here with Mr. Monbiot’s kind permission.

Slim Chance
11th August 2015
New evidence suggests that obesity might be incurable. So why does the government propose to punish sufferers?
By George Monbiot, published in the Guardian 12th August 2015
Is overeating more addictive than crack cocaine? It’s hard to compare addiction rates, or to produce a clear definition that holds true across all substances and behaviours. But consider this crude contrast. Between 10 and 20% of people who use crack cocaine become addicted to it. Across a 9-year study of 176,000 obese people, 98.3% of the men and 97.8% of the women failed to return to a healthy weight. Once extreme overeating begins, it appears to be almost impossible to stop.
A paper published in the journal Neuroscience and Biobehavioral Reviews proposed that “food addiction” is a less accurate description of this condition than “eating addiction”. There is little evidence that people who are driven to overeat become dependent on a single ingredient; instead they tend to seek out a range of highly palatable, energy-dense foods, of the kind with which we are now surrounded.
The activation of reward systems in the brain and the loss of impulse control are similar to those involved in dependency on drugs. But eating addiction appears to be more powerful. As the same paper notes, in laboratory experiments “a majority of rats will prefer a sweet reward over a cocaine reward.”
Once you become obese, an article published in the Lancet this year explains, biological changes lock you in. Fat cells proliferate. The brain becomes habituated to dopamine signalling (the reward pathway), driving you to compensate by increasing your consumption. If you try to lose weight, the body perceives that it is being starved, and powerful adaptations (such as an increase in metabolic efficiency) try to bounce you back to your previous state. People who manage, against great odds, to return to a normal weight must consume 300 fewer calories per day than those who have never been obese, if they are not to put the weight back on. “Once obesity is established, … bodyweight seems to become biologically stamped in”. The more weight you lose, the stronger the biological pressure to get back to your former, excessive size.
The researchers find that “these biological adaptations often persist indefinitely”: in other words, if you have once been obese, staying slim means sticking to a strict diet for life. The best you can hope for is not a dietary cure, but “obesity in remission”. The only effective, long-term treatment for obesity currently available, the same paper says, is bariatric surgery. This can cause a number of grim complications.
I know this statement will be unwelcome. I too hate the idea that people cannot change their circumstances. But the terrible truth is that, except through surgery, for the great majority of sufferers, obesity is an incurable disease. In one respect it resembles cancer: the changes in lifestyle that might have prevented it are unlikely to be of use in curing it.
Fat-shaming is worse than useless. Another paper found that the more weight-conscious people are, the more likely they are to overeat: the stress it induces is a trigger for comfort eating. As Sarah Boseley points out in her book The Shape We’re In, “the diet industry … is one of the biggest frauds of our time”. For the obese, temporary reductions in weight will almost inevitably be reversed.
People who are merely overweight, rather than obese (in other words who have a BMI of between 25 and 30) appear not to suffer from the same biochemical adaptations: their size is not “stamped in”. For them, changes of diet and exercise are likely to be effective. But urging obese people to buck up produces nothing but misery.
The crucial task is to reach children before they succumb to this addiction. As well as help and advice for parents, this surely requires a major change in what scientists call “the obesogenic environment” (high energy foods and drinks and the advertising and packaging that reinforces their attraction). Unless children are steered away from overeating from the beginning, they are likely to be trapped for life.
You might have expected this knowledge to lead to acceptance, empathy and an end to stigmatisation. Fat chance. A fortnight ago, just after the figures I mentioned at the top of this article were published, David Cameron announced a review that could lead to obese people being deprived of social security payments if they fail to accept “treatment” for their condition.
This review, conducted by Dame Carol Black, has already pre-empted its conclusions: eight times it describes obesity as “treatable”. Really? How? It will consider the case “for linking benefit entitlements to take up of appropriate treatment”. Are Cameron and Black proposing that benefit claimants will be forced to undergo surgery? Or will they be pressed into a useless and punitive dietary regime? These proposals look to me like a transfer of blame for the disease away from food manufacturers and advertisers and onto those afflicted.
Why do we have an obesity epidemic? Has the composition of the human species changed? Have we suffered a general collapse in willpower? No. The evidence points to high-fat, high-sugar foods that overwhelm the impulse control of children and young adults, packaged and promoted to create the impression that they are fun, cool and life-enhancing. Many are placed in the shops where children are bound to encounter them: around the tills, at grasping height.
The disease will keep ravaging the population (and slowly overwhelm the health service) until these circumstances change. But the government’s sole contribution has been to tear down mandatory controls, replacing them with a voluntary – and therefore useless – “responsibility deal” with manufacturers and retailers. It allows them to choose whether or not to use the traffic light system, which is the most effective way of informing people about the likely impact of what they eat. And many corporations, unsurprisingly, choose not to. As far as nutritional content is concerned, food manufacturing is effectively unregulated.
Industry and government will resist the obvious solutions until they can be resisted no longer. Eventually, the change will have to happen: similar restrictions on advertising, sponsorship, display and accessibility to those imposed on the tobacco pedlars. One day, though not before many thousands have needlessly died, it will become illegal to advertise any food or drink that merits a red traffic light warning. They will be sold only in plain packaging, with health warnings, on high shelves.
Does this seem draconian to you? If so, remember that obesity afflicts a quarter of the adult population, and is rising rapidly. It causes a range of hideous conditions, just one of which – diabetes – accounts for one sixth of NHS admissions and 10% of its budget. If smoking demands fierce intervention, why not overeating?
This is the choice we face. To recognise that the only humane and effective means of addressing the obesity epidemic is to prevent more people from being hooked, by restricting the pushers. Or to continue a programme of fat-shaming, bullying and compulsory treatment, whose only likely outcome is unhappiness. Now ask yourself again: which of these two options is draconian?
Let me close with an image. The image that George Monbiot believes will be seen very widely and representing the same common-sense in eating that we have been used to with regard to No Smoking signs.
Jean and I were out for much of yesterday resulting in me not sitting down to compose today’s post until nearly 5pm (PDT) in the afternoon. I must admit I didn’t have a clue as to what to write about. Then sitting in my email inbox was another email from Chris Gomez with this short but valuable sentence, “Love is real….Check this out! (via ABC7 Los Angeles local news iOS app) Study reveals scientific reason your dog is happy to see you.” Chris included a link to the ABC7 news item. I’m republishing it here.

STUDY REVEALS SCIENTIFIC REASON YOUR DOG IS HAPPY TO SEE YOU

Is your dog overwhelmed with joy anytime you walk through the door? There’s a scientific reason behind their excitement, a new study shows, and it’s not just because you feed them.
Researchers at Emory University used functional magnetic resonance imaging (fMRI) to scan dogs’ brains for activity when they were shown images of dog faces, human faces and ordinary objects.
The dogs’ temporal lobes lit up “significantly more” when presented with the faces than with the objects. These findings suggest that dogs may recognize both human and dog faces.
Facial recognition causes dog brains to activate in the same areas as in monkey and human brains, the study found. This is separate from the “reward areas” that would be triggered by anticipation of food.
“What we’re finding with the imaging work is that dogs love their humans-and not just for food,” researcher Gregory Berns told io9. “They love the company of humans simply for its own sake.”
“The existence of a face-selective region in the temporal dog cortex opens up a whole range of new questions to be answered about their social intelligence,” the researchers explained, such as whether dogs can understand different facial expressions and whether they can read body language.
This isn’t the first time scientists have explored what makes dogs’ tails wag with excitement when reunited with their owners. A January study that Berns was also involved in found that dogs have a positive reaction to the scent of familiar humans compared with other smells, even those of other dogs.
The results of that study “suggested that not only did the dogs discriminate that scent [of familiar humans] from the others, they had a positive association with it.”
A 2013 behavioral study found that dogs can show when they’re happy to see their owners by lifting their eyebrows. Their left eyebrow went up when they saw their respective owners, the study found. They didn’t have this reaction for other things that may excite them, such as attractive toys.

Granted there was some overlap with Monday’s post but there was more than enough in the ABC7 article to warrant sharing it with you.
