Causes productive ecosystems that would otherwise be less productive.

Glaciers Ecosystems

What is going to happen to 1/3 of the world population?

That’s why

The world is one living organism.

•All organisms share the same DNA structure. We are the same organism just divided, changed, and recombined.
