C Some people are saying, “Take extinction ( 灭绝 ) off your plate. What? I already take shorter showers. Every week, I walk whenever I can. I ride my bike a lot. I share cars. Isn't that enough? Agriculture is one of the largest contributors to greenhouse gas emissions ( 排放 ) 一 greater than all transport put together — and our present dietary choices are propelling us toward extinction. Raising livestock for animal products requires far more land? water and energy than producing plant foods. Producing a kilo of beef produces 27 kilos of CO 2 , compared to 0. 9 kg per kilo of beans. One kilo of beef delivers 194 grams protein ( 蛋白质 ); one kilo of beans : 246 grams protein. According to an Oxford study, adopting vegan diets globally would cut food-related emissions by 70%. But how can you make beans taste good? One can start by picking up a veg. co-book or doing a web search for “vegan beans recipe". You'll find 825,000 tasty results within 0. 51 seconds. The Scientific Committee of the Dietary Guidelines now provides evidence that diets with more plant foods and less animal products are linked with less environmental damage. Many scientists are calling for a great reduction in livestock production to change climate and to use less water, fossil fuels? pesticides and fertilizers. The Academy of Nutrition and Dietetics makes the point that, compared with producing 1 kilo of beef protein, 1 kg protein from beans requires 18 times less land, 10 times less water, 9 times less fuel, 12 times less fertilizer, and 10 times fewer pesticides. Beef production produces considerably more waste than other animal or fish farming, but they are all strong polluters. Does this situation strike you as crazy? By relying on meat and other animal products, we make ourselves fat, raise our risk of many diseases and then destroy our planet. Want to really make a change?
