'Never mind the economic crisis. Focus for a moment on a more urgent threat: the great food recession that is sweeping the world faster than the credit crunch. You have probably seen the figures by now: the price of rice has risen by three-quarters over the past year, that of wheat by 130%. There are food crises in 37 countries. One hundred million people, according to the World Bank, could be pushed into deeper poverty by the high prices.

But I bet that you have missed the most telling statistic. At 2.1bn tonnes, the global grain harvest broke all records last year – it beat the previous year's by almost 5%. The crisis, in other words, has begun before world food supplies are hit by climate change. If hunger can strike now, what will happen if harvests decline?

There is plenty of food. It is just not reaching human stomachs. Of the 2.13bn tonnes likely to be consumed this year, only 1.01bn, according to the United Nation's Food and Agriculture Organisation, will feed people...

While 100m tonnes of food will be diverted this year to feed cars, 760m tonnes will be snatched from the mouths of humans to feed animals - which could cover the global food deficit 14 times. If you care about hunger, eat less meat...

In his magazine The Land, Simon Fairlie has updated the figures produced 30 years ago in Kenneth Mellanby's book Can Britain Feed Itself?

Even if we reduced our consumption of meat by half, a mixed farming system would need 4.4m hectares of arable fields and 6.4 million hectares of pasture. A vegan Britain could make a massive contribution to global food stocks...

The Food and Agriculture Organisation calculates that animal keeping is responsible for 18% of greenhouse gas emissions. The environmental impacts are especially grave in places where livestock graze freely. The only reasonable answer to the question of how much meat we should eat is as little as possible...'
