Eating Meat = Eating up Land

Eating Meat = Eating up Land

A human population expected to grow by 3 billion, a shift in developing countries to eating more meat, and global consumption on track to double in 40 years point to the mother of all food crises down the road. How much food we grow is not just limited by the amount of available land but meat-eaters need far more space than vegetarians. A Bangladeshi family living off rice, beans, vegetables and fruit may live on an acre of land or less, while the average American, who consumes around 270 pounds of meat a year, needs 20 times that.

Nearly 30% of the available ice-free surface area of the planet is now used by livestock, or for growing food for those animals. One billion people go hungry every day, but livestock now consumes the majority of the world's crops. A Cornell University study in 1997 found that around 13m hectares of land in the US were used to grow vegetables, rice, fruit, potatoes and beans, but 302m were used for livestock. The problem is that farm animals are inefficient converters of food to flesh. Broiler chickens are the best, needing around 3.4kg to produce 1kg of flesh, but pigs need 8.4kg for that kilo.

Other academics have calculated that if the grain fed to animals in western countries were consumed directly by people instead of animals, we could feed at least twice as many people – and possibly far more – as we do now.

To make matters worse, our hunger to eat animals has led to overstocking of fragile lands and massive soil erosion and desertification. Overgrazing, from the down lands of southern England to the uplands of Ethiopia and mountains of Nepal, causes great loss of fertility, as well as flooding.
