【Economist】Curbing greenhouse-gas emissions: Pardon!

中文导读畜牧业中牛羊等反刍动物的打嗝或放屁过程都会排放大量温室气体甲烷，加剧全球变暖。对此科学家已找到解决方法——芦笋藻（Asparagopsis）中有化学物质可以干扰制造甲烷的细菌，使动物肚子中的碳不被排出而进入体内能量生产过程。这样既能减少畜牧业中温室气体的排放，也能提高牲畜的生长速率。The answer to livestock that burp methane may be seaweedAncient greek writings describe livestock eating seaweed, as do Icelandic sagas.
