亞馬遜雨林山火去年升30%，近七成山火發生在牛肉生產區。亞馬遜雨林現有80%被伐林的土地是用作養殖牛隻。巴西三大牛肉出口商稱致力確保「零伐林」的供應鏈，卻承認不清楚牛隻的來源，因牛隻都在成千上萬的繁殖及養殖埸之間轉移。

fires in Amazon rainforest rose 30% in 2019, and nearly 70% of the fires occurred in beef framing zones. Around 80% of deforested land are used for beef farming. The three biggest Brazil’s meat companies claimed to ensure zero deforestation commitment, but admired that they are not clear where their cattle came from because there are many indirect suppliers, and their cattle passes through numerous ranches before slaughter.
