In Australia, National Tree Day is on the last Sunday in July. In China, Tree Planting Day is on 12^th March. Trees are very important in our life. Trees make our city beautiful. We can get a lot of things from trees. We get fruit from trees. We also get wood from trees. We use wood to make pencils, desks and chairs. We can use wood to make paper, too. Trees can keep the air clean. They can cool the air, too. So we should love trees. We should plant more trees.
