- 據聯合國糧農組織報告,人類的肉類市場自1961年以來已經變為了原來的4倍還多,從當時約7000萬噸(的肉類消耗量)達到了2010年的將近3億噸。而大部分的增長則是來自印度和中國。這兩個國家約佔世界總人口的三分之一,而他們曾經主要依賴著米飯和蔬菜作為食物。現在,蓬勃發展的經濟使他們去購買肉類,而大片的亞馬遜雨林都被砍掉,以滿足前所未有的、對玉米和大豆作為動物飼料的需求。 這還並不是人類對肉類的需求所帶給世界的所有事情。根據聯合國糧農組織在2006年的一項研究,畜牧業在全球溫室氣體排放中佔了大約18%。然後需要考慮的就是飼養家畜所需要的糧食和水。美國國家廣播電臺(NPR)發現,制作一個單獨的、0.25磅的牛肉漢堡排——其中包括黃瓜、生菜和面包,需要6.7磅的谷物和飼料以及52.8加侖的水。盡管在談話節目中不斷的聲稱他們在這些日子裏吃得更為健康,但美國人仍是在地球上吃肉最為貪得無厭的人——人均每年會大吃特吃掉270.7磅肉。這要比世界平均水平102.5磅的兩倍還多。... 原文在此

-Humanity's meat market has more than quadrupled since 1961, from about 70 million tons back then to almost 300 million tons in 2010, according to the FAO. Much of that increase has come from India and China. Those two countries, accounting for about a third of the world's total population, once relied mostly on rice and vegetables to feed their people. Now their booming economies are enabling them to buy meat, and vast tracts of Amazon rainforest are being clear-cut to satisfy the unprecedented demand for corn and soybeans as animal feed. And that's not all that humanity's appetite for meat is doing to the world. The livestock industry accounts for some 18 percent of global greenhouse gas emissions, according to a 2006 FAO study. Then there's the grain and water it takes to raise cattle. NPR ran the numbers and found that it takes 6.7 pounds of grain and forage and 52.8 gallons of water to produce a single quarter-pound ground-beef patty - hold the pickle, the lettuce and the bun. And Americans are in no position to wag a finger. Despite the incessant claims on talk shows that they're eating healthier these days, Americans remain among the most voraciously carnivorous people on the planet, devouring 270.7 pounds of meat a year per capita. That's way more than double the world average of 102.5 pounds.... Original article here
