Well, it's just the physical appearance of the earth, so basically the shape of the land's surface.

好吧，这只是地球的物理外观，所以基本上是陆地表面的形状。

Meanwhile, warmer land surfaces mean parcels of air over land are also picking up more water than they used to, making dry places drier and droughts harsher.

同时，升温的地表意味着，地表上方的空气中所含水分也高于常态，这会导致干燥的地方更加干燥，干旱更严重。

We would have plants assimilating more and more and more carbon forever, and we will just see a very, very strong sink of carbon in the land surface.

So it actually moved by humping its body along like this, as it moved along on the land surface, and beautifully preserved in these rocks.

所以它实际上是通过像这样哼哼唧唧地移动它的身体，就像它在陆地表面移动一样，并保存在这些岩石中。

Well, we don't want that to happen for various reasons 'cause we don't wanna lose perhaps the greatest harbor of diverse life under Earth's land surface.

好吧，出于各种原因我们不希望这种情况发生，因为我们不想失去地球陆地表面下也许是多样化生命的最大港湾。
