根據衛星數據顯示的信息，古老的、富含碳的熱帶森林繼續以驚人的速度消失。美國馬裡蘭大學對高度為五米以上的樹木的研究稱，在2019年，每六秒就有一片足球場大小的原始森林消失。
For scientists, the loss of older trees and tropical rainforests is a double blow to life on Earth. As well as storing massive amounts of carbon, they're hotspots of biodiversity as the homes of orangutans, jaguars, and tigers.
對科學家們來說，古老樹木和熱帶雨林的消失是對地球生命的一個雙重打擊。除了儲存大量的碳以外，古老樹木和熱帶雨林還是生物多樣性熱點地區，是紅毛猩猩、美洲豹和老虎的家園。
According to the new data, these primary forests continue to be destroyed at alarming rates. Brazil accounted for over a third of all losses last year, with deforestation for agriculture the main motive.
據新數據顯示，這些原始森林持續以驚人的速度遭到毀壞。去年，巴西原始森林損失的比例佔所有損失的三分之一以上，其主要緣由是為了農業生產砍伐森林。
The end of 2019 also saw dramatic fires in Australia leading to a sixfold increase in the total number of trees lost compared to 2018.
2019年底，澳大利亞也發生了嚴重森林火災，導致樹木損失總數比2018年增加了六倍。
