牛屁中的甲烷会污染环境吗？
我打赌你听说过牛屁中含有大量甲烷从而污染臭氧层的说法。
I bet you have heard the story about how cows fart so much methane that it is endangering the ozone layer.
我个人最喜欢的是“牛屁二氧化碳”的应用程序-“牛胀气”工具-计算你在牛屁里的碳足迹。
My personal favourite is the "cow fart CO2" app, the "Bovine Flatulence" measurement that measures your carbon footprint in cow farts.
