垃圾填埋场着火不仅会散发出恶臭，还会对环境造成具有毁灭性的后果。甲烷就是罪魁祸首，这是一种经常被低估的温室气体，主要由食品系统、有机废物和牛打嗝产生。生化工程师  马塞洛·梅纳 解释了这种污染物的来源、为什么需要在 2050 年前将其排放量减少一半，以及我们可以提供帮助的措施。

甲烷，隐形的气候恶棍

Methane from landfills, food waste, and livestock is fueling nearly half of global warming, yet often goes unnoticed compared to carbon dioxide. Fires at towering landfills, like the one in Delhi, can burn for days and pollute entire cities. Cutting methane emissions in half by 2050 is essential to keep warming under 1.5 degrees Celsius. Solutions like composting, better livestock practices, and using emerging technology to spot leaks can deliver cleaner air and improved lives right now.
