This ties in with one of my personal hobbyhorses.
If we want to reduce our impacts this century, the paper concludes, it is consumption we must address. Population growth is outpaced by the growth in our consumption of almost all resources. There is enough to meet everyones need, even in a world of 10 billion people. There is not enough to meet everyones greed, even in a world of 2 billion people.
So lets turn to a population crisis over which we do have some influence. Im talking about the growth in livestock numbers. Human numbers are rising at roughly 1.2% a year, while livestock numbers are rising at around 2.4% a year. By 2050 the worlds living systems will have to support about 120m tonnes of extra humans, and 400m tonnes of extra farm animals.
Raising these animals already uses three-quarters of the worlds agricultural land. A third of our cereal crops are used to feed livestock: 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. And now the grain that farm animals consume 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.
And a reprise of my graphic of the situation:

(21,088 posts)A lot of people, of which I am one, can only operate properly on a diet that consists mainly of animal fats and proteins. Eating a really healthy vegetarian diet that avoids most grains and root starches is both difficult and expensive, so people tend to fall back to Twinkies and Coke.
It's ironic that I, of all people, have to live on a diet that contains about 600 grams of meat a day. It's not my birthright so much as my death-avoidance strategy...
I try to eat very fatty meats, which means I'm probably getting about 100 gm of protein on an average day. I'm in ketosis all the time, so any excess protein is being converted to glucose through gluconeogenesis.
I'm two years into this diet, I've lost 50 lb, my BP and blood lipids have come back down to normal, my acid reflux has vanished, I no longer retain fluid in my legs and feet, and my moods don't swing and crash any more. Whatever I'm doing sure isn't hurting my body. My conscience is another matter, though.
Between 20% and 30% of the population suffers from this problem, defined as metabolic syndrome and insulin resistance. Many people (I'm one) think that diets chronically high in starches (i.e. sugars) are the main culprit.

Feed lots aren't the answer -- so what is?

(21,088 posts)The number of humans is massively unsustainable, so their dietary needs are even more so. That is, if we we're trying to preserve an intact biosphere - which is impossible anyway because of the damage we've already inflicted on it.
There is no good answer to the conundrum of the human presence on this planet.

Political corruption prevents, so far, renewable energy development, where we have huge solar, wind, wave, geothermal potential. We need economic system change.
