Importance of trees to our earth

Trees help living things, including human beings, in many ways. Some people plant trees and some others put efforts into cutting them down. In Kenya and the whole world, the person who plants most trees is Prof Wangari Maathai. She is very important to the world because she knows the importance of trees. Trees freshen the air so that we can have good oxygen. Trees help in the formation of rainfall and that is why there is little rain in deserts. Wild animals that attract tourists live in places with trees. I want to follow Maathai’s example and plant trees.
