Countless studies claim that eating meat harms the planet and contributes to global warming. The U.N.'s 2006 Food and Agriculture Organization report states that meat produces 18% of the world's carbon emissions —more than the global transport infrastructure. But in his new book, Meat: A Benign Extravagance, Simon Fairlie, a British farmer and former editor of the Ecologist magazine, tears apart the theory that being carnivorous is bad for the planet —and says that eating moderate amounts of meat could be greener than going vegan.
Simon Fairlie 是英国的一个农场主，曾是《生态学家》杂志的编辑，在一本新书中他介绍道食用适量的肉类有益于环境。
Why is livestock beneficial to the environment rather than being bad for the planet. ?
Every agricultural system produces a surplus of waste and hard-to-use biomass that is best kept in the food chain by feeding it to livestock. Meat or dairy produced this way has little extra environmental impact. Animals kept on small farms also produce benefits, such as fending off predators and pests and fertilizing soil.
What are the most sustainable types of meat to eat?
Pigs fed off food waste, whey and other forms of garden and agricultural waste. Dairy cows that are eating grass and clover as part of mixed-arable rotation. They have very little toll on the environment and are, on balance, benign. The way forward is to switch to organic farming. We would have to cut meat consumption by half, but our dairy intake would remain about the same.
