You couldn’t make it up!

However hard one tried to!

In Chapter Eight, Behaviours and Relationships, I speak of how the development of humans has been, unsurprisingly, the result of our human behaviours. Adding that it is likely that our behaviours have been damaging, in varying degrees, to the survival of our species and countless others for a very long time. Continuing:

But 2,000 years ago, the global population of man was only 300 million persons[1]. It took 1,200 years for that global population to become 1 billion persons; in 1800. Now track the intervals as we come forward in time.

In 1927, just 127 years later, the two-billionth baby was born. In 1960, only 33 years on, came the birth of the three-billionth baby. Just 16 years later, in 1974, the four-billionth baby was born. In 1987, now only 13 years later, we have a population of five billion persons. Around October 1999, the sixth-billionth baby was born.
The growth rate of global population is slowing[2] but nevertheless it is trending to a billion additional persons every decade. In other words, a 100-million population growth every year, or about 270,000 more persons every single day.

Combine man’s behaviours rooted in times way back with this growth in population and we have the present situation. A totally unsustainable situation for one basic and fundamental reason. We all live on a finite planet.

[2] According to UN’s 2010 revision to its population projections, world population will peak at 10.1bn in 2100 compared to 7bn in 2011. A 2014 paper by demographers from several universities and the United Nations Population Division forecast that the world’s population will reach about 10.9 billion in 2100 and continue growing thereafter. However, some experts dispute the UN’s forecast and have argued that birthrates will fall below replacement rate in the 2020s. According to these forecasters, population growth will be only sustained till the 2040s by rising longevity but will peak below 9bn by 2050.

A growth of about 270,000 more persons every single day!

I am sure that I am not alone in seeing this growth in our population as something that is both unsustainable and a critical component of long-term damage to our planet.

But George Monbiot in a recent essay, in true Monbiot style, highlights an aspect of our human population and the damage resulting that would have never previously occurred to me.

Read it and see if you don’t agree likewise. (Again, there are just too many links in George’s essay to reconstruct in this republishing and, as the other day, I have highlighted those phrases that are a link to other material in red. Go here if you wish to further investigate those links.)


Pregnant Silence

19th November 2015

It’s about time we discussed the real population crisis.

By George Monbiot, published in the Guardian 18th November 2015

This column is about the population crisis. About the breeding that’s laying waste to the world’s living systems. But it’s probably not the population crisis you’re thinking of. This is about another one, that we seem to find almost impossible to discuss.

You’ll hear a lot about population in the next three weeks, as the Paris climate summit approaches. Across the airwaves and on the comment threads it will invariably be described as “the elephant in the room”. When people are not using their own words, it means they are not thinking their own thoughts. Ten thousand voices each ask why no one is talking about it. The growth in human numbers, they say, is our foremost environmental threat.

At their best, population campaigners seek to extend women’s reproductive choices. Some 225 million women have an unmet need for contraception. If this need were answered, the impact on population growth would be significant, though not decisive: the annual growth rate of 83 million would be reduced to 62m (1). But contraception is rarely limited only by the physical availability of contraceptives. In most cases, it’s about power: women are denied control of their wombs. The social transformations they need are wider and deeper than donations from the other side of the world are likely to achieve.

At their worst, they seek to shift the blame from their own environmental impacts. Perhaps it’s no coincidence that so many post-reproductive white men are obsessed with human population growth, as it’s about the only environmental problem of which they can wash their hands. Nor, I believe, is it a coincidence that of all such topics this is the least tractable. When there is almost nothing to be done, there is no requirement to act.

Such is the momentum behind population growth, an analysis in the Proceedings of the National Academy of Sciences discovered, that were every government to adopt the one-child policy China has just abandoned, there would still be as many people on Earth at the end of this century as there are today. If two billion people were wiped out by a catastrophe in mid-century, the planet would still hold a billion more by 2100 than it does now.

If we want to reduce our impacts this century, the paper concludes, it’s consumption we must address. Population growth is outpaced by the growth in our consumption of almost all resources. There is enough to meet everyone’s need, even in a world of 10 billion people. There is not enough to meet everyone’s greed, even in a world of 2 billion people.

So let’s turn to a population crisis over which we do have some influence. I’m talking about the growth in livestock numbers. Human numbers are rising at roughly 1.2% a year. Livestock numbers are rising at around 2.4% a year. By 2050, the world’s living systems will have to support about 120m tonnes of extra human, and 400m tonnes of extra farm animals(2).

Raising them already uses three quarters of the world’s agricultural land. One third of our cereal crops are used to feed them. This may rise to roughly half by 2050. More people will starve as a result, because the poor rely mainly on grain for their subsistence, and diverting it to livestock raises the price. Now the grain that farm animals eat is being supplemented by oil crops, particularly soya, for which the forests and savannahs of South America are being cleared at shocking rates.

This might seem counter-intuitive, but were we to eat soya, rather than meat, the clearance of natural vegetation required to supply us with the same amount of protein would decline by 94%. Producing protein from chickens requires three times as much land as protein from soybeans. Pork needs nine times, beef 32 times.

A recent paper in the journal Science of the Total Environment suggests that our consumption of meat is likely to be “the leading cause of modern species extinctions”. Not only is livestock farming the major reason for habitat destruction and the killing of predators, but its waste products are overwhelming the world’s capacity to absorb them. Factory farms in the US generate 13 times as much sewage as the human population. The dairy farms in Tulare county, California produce five times as much as New York City.

Freshwater life is being wiped out across the world by farm manure. In England, as I reported last week, the system designed to protect us from the tide of crap has comprehensively broken down. Dead zones now extend from many coasts, as farm sewage erases ocean life across thousands of square kilometres.

Livestock farming causes around 14% of the world’s greenhouse gas emissions: slightly more than the output of the world’s cars, lorries, buses, trains, ships and planes. If you eat soya, your emissions per unit of protein are 20 times lower than eating pork or chicken, and 150 times lower than eating beef.

So why is hardly anyone talking about the cow, pig, sheep and chicken in the room? Why are there no government campaigns to reduce the consumption of animal products, just as they sometimes discourage our excessive use of electricity? A survey by the Royal Institute of International Affairs found that people are not unwilling to change their diets, once they become aware of the problem, but that many have no idea that livestock farming damages the living world.

It’s not as if eating less meat and dairy will harm us. If we did as our doctors advise, our environmental impacts would decline in step with heart disease, strokes, diabetes and cancer. British people eat, on average, slightly more than their bodyweight in meat every year, while Americans consume another 50%: wildly more, in both cases, than is good for us or the rest of life on Earth.

But while plenty in the rich world are happy to discuss the dangers of brown people reproducing, the other population crisis scarcely crosses the threshold of perception. Livestock numbers present a direct moral challenge, as in this case we have agency. Hence the pregnant silence.


  1. While the number of unintended pregnancies would fall by 52m (or 70%), this does not mean that the number of babies would fall by the same amount. The Guttmacher/UNFPA report breaks down the outcome thus: “21 million fewer unplanned births; 24 million fewer abortions; six million fewer miscarriages; and 0.6 million fewer stillbirths.”
  2. Additional global meat consumption by this date is estimated to be roughly 200 million tonnes. Boned meat comprises roughly half the weight of a living animal. So total additional livestock biomass will be in the order of 400 million tonnes, or 400 billion kg. The average human weight is 52 kg and the anticipated rise in population by 2050 is 2.3 billion (the median estimate is 9.7 billion by that date). So the additional human weight is likely to be somewhere around 120 billion kg.


Powerful reasons to turn vegetarian or vegan. And well done if you are already there. Well done, indeed!

  1. Aaah. As a feminist who considers bodily autonomy to be a fundamental right, and a strict vegetarian would-vegan, then, yes, I do agree. There’s actually nothing new being said here. People just don’t like the message and the perceived smug sanctimonious attitude from non-meat eaters. It’s not very difficult. Yes, there’s a solution. This is it. And yes, it will impact on your choices and your lifestyle. Some time ago, I was chatting with a former aid worker, who said, there’s enough food available to feed people. There is no need for starvation. But no one wants to make it happen.

    I’ll be honest, when I wasn’t vegetarian, I wouldn’t have liked someone telling me I couldn’t eat meat, fish, chicken if I wanted to. What really firmed up my changes was the ethical stance. There is no need for an animal to be killed for me to eat. We had TVP in a bolognaise sauce on Sat. Yesterday we had some curried stuffed peppers with sauce afghan (tomato, basically). But we live in a selfish – and greedy – world 😦


    1. I agree with all that you say. Jean has been a vegetarian all her adult life and I ” converted” soon after living with her. Pity our dogs can’t be the same, but they can’t.

      Thanks for such a brilliant reply.


  2. Someone in the blogosphere introduced me to the film ‘Cowspiracy’ recently – was it yourself Paul? Anyway, I thought it was excellent, and certainly opened my eyes to much of that which George writes of in the above article.
