Trees are one of the most important things on the earth. They are like the lungs of the earth. They take in carbon dioxide and make oxygen. We can't live without oxygen. Trees can also cool down the air in hot summer. When it rains, trees can stop the water from washing the earth away. They can also stop the wind from blowing the earth away.
Trees provide us with a lot of things. We get fruit and nuts from trees. We also get wood from them. We use wood to make desks, chairs and many other things. Trees can also give us shade. When we feel hot, we can sit under a tree and enjoy the cool air.
Today, many people cut down too many trees for wood and land. This is bad for the environment. We should plant more trees and look after the existing ones. Tree Planting Day is a good time for us to plant trees. It's on March 12th in China. Everyone should play a part in protecting trees.

Trees are our best friends. They are very useful in our life. First, they make the environment beautiful. Green trees can make our city look more lively. Second, they help to keep the air clean. They are natural air conditioners. Third, they can stop soil erosion (水土流失). Without trees, the earth will become sandy.
Many animals live in the trees. They make their homes there. Trees provide food for some animals, like birds and squirrels. If we cut down all the trees, many animals will lose their homes and food. They may even die out.
It's everyone's duty to protect trees. We should not only plant more trees but also look after them well. We should stop people from cutting down trees randomly. Let's work together to make our earth a green and beautiful home.
