Forests fulfill economical, ecological and also social services for us. They should be managed sustainably. Once upon a time a lot of earths land surface was covered with forests, before humanity developed into millions and billions until today. Planting billions of trees and millions of forests worldwide would help tackling climate change and global warming. Forests are vital for us.
