A counter-intuitive approach to stopping global warning.
About three weeks ago, the 22nd November to be precise, I published a post under the title of Our Beautiful Planet. It included the reply to an email that I had sent to Prof. Bill Ripple or, to give him his full nomenclature, William J. Ripple, Distinguished Professor of Ecology, Department of Forest Ecosystems and Society, Oregon State University, Corvallis, Oregon.
I reached out to the good Professor because I wanted to share with you what he thought were the top priorities in terms of how each and every one of us should change our lifestyle. You may well recall his reply (my emphasis):
Paul, Consider suggesting that if people want to help, they could have fewer children, reduce energy consumption such as driving autos and flying, avoid meat and eat mostly plant-based foods and avoid wasting food. Below are quotes from our paper. Bill
“It is also time to re-examine and change our individual behaviors, including limiting our own reproduction (ideally to replacement level at most) and drastically diminishing our per capita consumption of fossil fuels, meat, and other resources ….
… reducing food waste through education and better infrastructure; promoting dietary shifts towards mostly plant-based foods
Last Tuesday week, on the 5th December, there was an item published by NutritionFacts.org. It was called Meat is Heat: The Effects of Diet on Global Warming.
I am keeping my fingers crossed that Dr. Michael Greger is happy for me to republish this article in full. For it so underlines what Professor Ripple is promoting. (Indeed, further browsing on the NutritionFacts website showed that articles are published under the Creative Commons License arrangement.)

Meat is Heat: The Effects of Diet on Global Warming
One of the most prestigious medical journals in the world editorialized that climate change represents “the biggest global health threat of the 21st century.” Currently, chronic diseases are by far the leading cause of death. Might there be a way to combat both at the same time? For example, riding our bikes instead of driving is a win-win-win for the people, planet, and pocketbook. Are there similar win-win situations when it comes to diet?
As I discuss in my video Diet and Climate Change: Cooking Up a Storm, the foods that createthe most greenhouse gases appear to be the same foods that are contributing to many of our chronic diseases. Researchers found that meat (including fish), eggs, and dairy had the greatest negative environmental impact, whereas grains, beans, fruits, and vegetables had the least impact. And not only did the foods with the heaviest environmental impact tend to have lower nutritional quality, but they also had a higher price per pound. So, avoiding them gives us that triple win scenario.
The European Commission, the governing body of the European Union, commissioned a study on what individuals can do to help the climate. For example, if Europeans started driving electric cars, it could prevent as much as 174 million tonnes of carbon from getting released. We could also turn down the thermostat a bit and put on a sweater. But the most powerful action people could take is shift to a meat-free diet.
What we eat may have more of an impact on global warming than what we drive.
Just cutting out animal protein intake one day of the week could have a powerful effect. Meatless Mondays alone could beat out a whole week of working from home and not commuting.
A strictly plant-based diet may be better still: It’s responsible for only about half the greenhouse gas emissions. Studies have suggested that “moderate diet changes are not enough to reduce impacts from food consumption drastically.” Without significant reduction in meat and dairy, changes to healthier diets may only result in rather minor reductions of environmental impacts. This is because studies have shown that the average fossil energy input for animal protein production systems is 25 calories of fossil energy input for every 1 calorie produced—more than 11 times greater than that for grain protein production, for example, which is around 2 to 1.
Researchers in Italy compared seven different diets to see which one was environmentally friendliest. They compared a conventional omnivorous diet adhering to dietary guidelines; an organic omnivorous diet; a conventional vegetarian diet; an organic vegetarian diet; a conventional vegan diet; an organic vegan diet; and a diet the average person actually eats. For each dietary pattern, the researchers looked at carcinogens, air pollution, climate change, effects on the ozone layer, the ecosystem, acid rain, and land, mineral, and fossil fuel use. You can see in the video how many resources it took to feed people on their current diets, all the negative effects the diet is having on the ecosystem, and the adverse effects on human health. If people were eating a healthier diet by conforming to the dietary recommendations, the environmental impact would be significantly less. An organic omnivorous diet would be better still, similar to a vegetarian diet of conventional foods. Those are topped by an organic vegetarian diet, followed by a conventional vegan diet. The best, however, was an organic vegan diet.
The Commission report described that the barriers to animal product reduction are largely lack of knowledge, ingrained habits, and culinary cultures. Proposed policy measures include meat or animal protein taxes, educational campaigns, and putting the greenhouse gas emissions information right on food labels.
Climate change mitigation is expensive. A global transition to even just a low-meat diet, as recommended for health reasons, could reduce these mitigation costs. A study determined that a healthier, low-meat diet would cut the cost of mitigating climate change from about 1% of GDP by more than half, a no-meat diet could cut two-thirds of the cost, and a diet free of animal products could cut 80% of the cost.
Many people aren’t aware of the “cow in the room.” It seems that very few people are aware that the livestock sector is one of the largest contributors to greenhouse gas emissions. But that’s changing.
The UK’s National Health Service is taking a leading role in reducing carbon emissions. Patients, visitors, and staff can look forward to healthy, low-carbon menus with much less meat, dairy, and eggs. “Evidence shows that as far as the climate is concerned, meat is heat.”
The Swedish government recently amended their dietary recommendations to encourage citizens to eat less meat. “If we seek only to achieve the conservative objective of avoiding further long-term increases in [greenhouse gas] emissions from livestock, we are still led to rather radical recommendations” such as cutting current consumption levels in half in affluent countries—“an unlikely outcome if there were no direct rewards to citizens for doing so. Fortunately, there are such rewards: important health benefits…” By helping the planet, we can help ourselves.
There are tons of articles on diet and sustainability. It’s such an important topic that I may review the new science once every year or two. When the U.S. Department of Agriculture entered these waters, the meat industry appeared to freak out, and the Dietary Guidelines debate continues.

Just reflect on the key message from this article (my emphasis):
“A study determined that a healthier, low-meat diet would cut the cost of mitigating climate change from about 1% of GDP by more than half, a no-meat diet could cut two-thirds of the cost, and a diet free of animal products could cut 80% of the cost.”
In other words, the most cost-effective way of mitigating climate change is to change to a diet free of animal products. Plus, it’s a damn sight healthier for you and me!

I only properly regained consciousness when the ambulance was speeding its way to Three Rivers Hospital in nearby Grants Pass.
Next, a sunrise photograph with the camera pointing to the East. The tree line follows the ridge of some hills the other side of Hugo Road. The picture taken on the 19th October at 07:20.
Now a close-up of the remains of a very old tree trunk with the trees that border Bummer Creek, that runs through our land, just showing through the morning mist. Taken on the 24th October at 09:05.
Regular readers will know that Jean and I are not believers in any religion; we are atheists. But to my way of thinking that puts even more pressure on me and Jean to try to make a difference. We do all that we can but there’s no doubt that we can do more.
