Forests.
As we all know that forests are necessary for the earth. Forests and plants give us oxygen to breathe. Without them we would die. That's why people are working so hard to stop/slow down Global Warming.

When forests burn they release carbon dioxide which is a greenhouse gas which tends to make the Earth warmer.
