Trees are important
Trees are very important to us.
Firstly,they take in carbon dioxide from the air and make oxygen.People and animals need oxygen to live.That's very important.
Secondly,trees are very useful.They provide us with wood and other products.Many small animals and inserts live in the trees.Some of them also get food from trees.
Moreover,trees can also stop water and soil from going away.If we have a lot of trees,we stop deserts from being large.
Last but not the least,trees are green.They can make our country even more beautiful.
However,in many parts of our country,people haven't realized the importance of trees.They cut them down at will.They are usually too lazy or too careless to plant and look after new trees.As a result,the forests continue to disappear.
To sum up,trees are very important.They are our good friends.We should plant more trees and take good care of them.
