How do trees affect the world around us?
The shade that trees give can cool the temperature of the air by almost 10 degrees. And the roots of trees hold together the forest floor and help to keep our drinking water clean. Trees also produce oxygen, which is what we need to breathe, and they give shelter for many animals and birds.

Foresters, people who take care of our forests, understand all the special things that trees do. It is their job to keep our forests healthy.
