Why vegans were right all along

This is one of the reasons why many people have returned to eating red meat at Christmas. Beef cattle appear to be happier animals. But the improvement in animal welfare is offset by the loss in human welfare. The world produces enough food for its people and its livestock, though (largely because they are so poor) some 800 million are malnourished. But as the population rises, structural global famine will be avoided only if the rich start to eat less meat. The number of farm animals on earth has risen fivefold since 1950: humans are now outnumbered three to one. Livestock already consume half the world's grain, and their numbers are still growing almost exponentially.

This is why biotechnology - whose promoters claim that it will feed the world - has been deployed to produce not food but feed: it allows farmers to switch from grains which keep people alive to the production of more lucrative crops for livestock. Within as little as 10 years, the world will be faced with a choice: arable farming either continues to feed the world's animals or it continues to feed the world's people. It cannot do both.
