Today, too many trees are still being cut down in many countries and floods all over the world are getting more and more serious. A lot of land has gone with them. This is a lesson from the nature.
When people move into a new place, they often cut down trees or pull out many wild plants to make farmland. Maybe they don’t think they can eat trees or grass. They don’t know that the floods and the wind can’t wash or blow the earth away easily because of the trees, and that many of these wild plants are food for some wild animals, if the animals can’t find enough plants to eat, they will die or have to leave the place.
The number of trees, deer, tigers, wild flowers and plants has changed much –less and less. We need to do more to keep the balance of the nature.
Now more “Great Green Walls” are needed to save a lot of land and wild animals all over the world.

People came to understand : to protect all living things on the earth means to protect people themselves
