A recent study found greenhouse gas emissions from human food production and consumption could add nearly 1 degree Celsius of warming to the Earth’s climate by 2100.
 　Food-based greenhouse gas emissions come from three major sources: meat from animals like cows, sheep and goats; dairy; and rice. Those three sources account for at least 19% each of food’s contribution to a warming planet, with meat contributing the most, at 33%.
 　Continuing the dietary patterns of today will push the planet past the 1.5-degree-Celsius limit of warming sought under the Paris climate agreement and will approach the agreement’s limit of 2 degrees Celsius.
 　It is imperative to change global food production and consumption. Experts have recommended eating less meat. California started a mandatory food waste recycling program in 2021 to reduce the emissions from decaying food.

　最近一項研究發現，人類生產和消費食物的方式所排放的溫室氣體，到2100 年左右，可能讓地球氣候升溫將近攝氏1 度。
　糧食為主的溫室氣體排放來自三個主要來源：牛、羊等紅肉，乳製品及稻米。根據最新的研究，這三個來源的食物對地球暖化的貢獻至少各占19%，其中紅肉的占比最大，達33%。
　如果持續現今的飲食模式會導致地球暖化，升溫幅度將超過巴黎氣候協定設定的攝氏1.5 度，並接近攝氏2 度的極限。
　改變全球食品生產和消費是當務之急。專家們建議少吃肉。而加州在2021年已開始一項強制性廚餘回收計畫，減少腐爛食物排放的溫室氣體。
