Where does all the carbon we release go?

我們排放的碳去了哪裡？

Carbon works in a natural cycle, present in all living things:

碳存在於所有生物體， 並在自然中循環：

in the soil, in the oceans, in the atmosphere

土壤、海洋、大氣層

and in rocks deep underground.

及地底深處的岩石中都有它的蹤跡。

When plants and other living things die,

當植物和其他生物死亡時，

much of their stored carbon makes its way back to the atmosphere

它們體內大部分的碳會回到大氣層，

until new plants grow and reabsorb the carbon.

直到新的植物生長並重新吸收碳。

But over millions of years,

但是經過數百萬年之後，

some of the carbon stored in ancient trees and sea life becomes rock

有些儲存在古樹和 海洋生物中的碳會變成岩石，

and some becomes fossil fuels:

有些則變成化石燃料：

coal, oil and natural gas.

煤炭、石油和天然氣。

Natural events like volcanic eruptions

火山爆發等自然現象

release some of the carbon trapped in rock.

會釋放一些鎖在岩石中的碳。

And human activities, like burning fossil fuels,

而燃燒化石燃料等人類活動

also release some of that prehistoric carbon.

也會排放一些史前時期的化石碳。

Today, humans release around 60 times more carbon

如今，人類每年在地球上排放的碳

than all the volcanoes on the planet each year.

大約是所有火山的 60 倍。

That overloads Earth's carbon cycle

這令地球的碳循環超出負荷，

and builds up in the atmosphere

並累積在大氣層和海洋裡。

and oceans.

Planting more trees will help, but trees alone can't get us to net zero.

種植更多樹木當然有幫助， 但卻無法幫我們達到淨零排放。

There's only one sure way to stop global warming.

只有一種方法一定能阻止全球暖化。

We must stop releasing this excess carbon into our air.

我們必須停止將多餘的碳 排放到空氣中。
