from the atmosphere through their leaves.

The remarkable thing is that even as carbon dioxide levels in the atmosphere rise,

最了不起的就是 就算二氧化碳在大氣層中的含量提高

trees respond by growing faster, so absorbing more carbon dioxide.

大樹也會通過更快生長的方式來吸收更多的二氧化碳

In fact, since humans started pumping greenhouse gases

實際上，自從人類開始向大氣層中輸入溫室氣體以來

into the atmosphere, the world's jungles have absorbed around

世界的叢林已經(jīng)吸收了

25% of all the carbon dioxide we've produced,
