Trees

There are a group of lifeforms on the planet that are capable of remarkable things.
They are among the oldest living lifeforms on the planet, and the largest.
They can metabolize carbon dioxide and exhale oxygen, pump water from under the ground and throughout their bodies without a single moving part.
A tree can be an entire habitat unto itself. A forest? A hundred-fold that.

Let me tell you about forests.

I'm scared to death about forests.
That's really all there is to say.
