Treating beef like coal would make a big dent in greenhouse-gas emissions 像对待煤炭一样对待牛肉会大大减少温室气体的排放
Beef emits 31 times more CO per calorie than tofu does 牛肉的二氧化碳排放量是豆腐的31倍
Coal emits 24 times more CO per unit of energy output than hydropower does 煤炭每单位能源产出的CO排放量是水电的24倍
One poll in 2014 found that steak was Americans’ favourite food. Unfortunately, by cooking so many cows, humans are cooking themselves, too.
2014年的一项民意调查发现，牛排是美国人最喜欢的食物。不幸的是，煮了这么多牛，人类也在煮自己。

Beef and dairy contribute over 70% of livestock greenhouse gas emissions (GHG), which collectively contribute ~6.3 Gt CO2 -eq/year and account for 14%-18% of human GHG emissions牛肉和乳制品贡献了超过70%的牲畜温室气体排放(GHG)，它们总共贡献了约6.3 Gt CO2 -eq/年，占人类温室气体排放的14%-18%

Novel ruminant supplements such as marine macro algae (Asparogopsis spp.) could significantly mitigate methane emissions in farming systems and no detectable impacts reported for animal health or meat quality.
新型反刍动物添加物，如海洋大型藻类(天冬藻)，可以显著减少养殖系统中的甲烷排放，且没有对动物健康或肉类质量产生可检测的影响。 |
