The Amazon rainforest has more plant and animal species than any other terrestrial ecosystem on Earth.

亚马逊雨林所拥有的动、植物物种远多于地球上任何陆地生态系。

Sometimes the effects of new terrestrial ecosystems, in the form of fields, pastures and plantations, are also considered.

有时田地、草原、种植园等新型陆地系统所产生的影响也考虑在内。

In terrestrial ecosystems, humans can breathe freely, but humans rely on technology, like SCUBA equipment, to inhale and exhale underwater.

在陆地生态系统中，人类可以自由呼吸，但在水下呼吸却要依靠一些技术手段，比如水肺潜水设备。

Many of them will protect some of the largest carbon storehouses of any terrestrial ecosystem on the planet.

其中许多将保护地球上任何陆地生态系统中一些最大的碳库。

It's the remarkable thing that sets them apart from the rest of our terrestrial ecosystem, and it's a profound example of what we call biodiversity.

难以置信的是雨林把它们和陆地生态系统隔离，雨林是生物多样性最有力的体现。

Global warming will increase the risk of irreversible loss of terrestrial, coastal, and marine ecosystems, affecting the survival of many fauna and flora species already under pressure.

全球变暖将增加陆地、沿海和海洋生态系统不可逆转损失的风险，影响许多已经面临压力的动植物物种的生存。

This  global event caused widespread extinctions, mass migrations, and disruptions to  marine and terrestrial ecosystems, including the swamps and jungles of South America.

这一全球事件导致了大范围的物种灭绝、大规模迁徙以及海洋和陆地生态系统（包括南美洲的沼泽和丛林）的破坏。

So, to this day, the legacy of those very first terrestrial ecosystems, and the forgotten Age of Synapsids, lives on in today's mammals, including you.

因此，直到今天，那些最早的陆地生态系统的遗产，以及被遗忘的突触动物时代，仍然存在于今天的哺乳动物身上， 包括你。

Let's go to the Amazon basin, again, the richest terrestrial ecosystem on land, climate science estimates the risk of the Amazon rainforest tipping over irreversibly to a savanna at three to five degrees of global mean surface temperature rise.

我们再来看看亚马逊盆地，这里是陆地上最丰富的生态系统，气候科学估计， 当全球平均地表温度上升 3 至 5 度时， 亚马逊雨林就有不可逆转地变成稀树草原的风险。
