全球最權威的世界璄境問題與趨勢分析研究機構--看守世界研究中心(Worldwatch) 最新一期雜誌發表的最新暖化研究報告指出: 畜牧業排放溫室氣體占51%, 是造成全球暖化最大主因. 2006年聯合國糧農組織所估計的18%顯然低估了畜牧業的溫排量.

這是任何關心地球暖化問題的人, 不能視而不見的事實, 敬愛的朋友, 若您還沒有改變自己的飲食,該是時候了!

 Livestock Emissions: Still Grossly Underestimated?

Washington, D.C.-The environmental impact of the lifecycle and supply chain of animals raised for food has been vastly underestimated, and in fact accounts for at least half of all human-caused greenhouse gases (GHGs), according to Robert Goodland and Jeff Anhang, co-authors of "Livestock and Climate Change" in the latest issue of World Watchmagazine.
A widely cited 2006 report by the United Nations Food and Agriculture Organization, Livestock's Long Shadow, estimates that 18 percent of annual worldwide GHG emissions are attributable to cattle, buffalo, sheep, goats, camels, pigs, and poultry. But recent analysis by Goodland and Anhang finds that livestock and their byproducts actually account for at least 32.6 billion tons of carbon dioxide per year, or 51 percent of annual worldwide GHG emissions.
Reviewing both direct and indirect sources of GHG emissions from livestock, the study finds that previous calculations have both underestimated and overlooked certain emissions sources as well as assigned emissions they deem to be livestock-related to the wrong sectors. The authors locate these discrepancies in previous analyses of livestock respiration, land use, and methane.
Based on their research, Goodland and Anhang conclude that replacing livestock products with soy-based and other alternatives would be the best strategy for reversing climate change. "This approach would have far more rapid effects on GHG emissions and their atmospheric concentrations-and thus on the rate the climate is warming-than actions to replace fossil fuels with renewable energy."
