Livestock generate 18 percent of world's greenhouse gases

A new report by the United Nations Food and Agriculture Organization found that domestic animals are a major source of greenhouse gases, producing 18% of the world's total - even more than transportation. Unless more sustainable techniques such as controlling soil erosion, providing animals with better diets, and using water more efficiently are adopted, the environmental impact of animal production will worsen, as world production of meat and dairy products is expected to double by 2050.
