Since the earliest times,trees have always been very useful and important to man who made use of them in many ways for his daily life.Today trees continue to play a very important part in many ways.They provide man with fruits,fuel for burning,wood for building and furniture.You can imagine what would happen if there were no trees in the world in which we're living.

In the tropics where it's very warm throughout the year,trees protect man from the heat of the hot sun.They are also very useful in protecting good and rich topsoil from being washed away,as there are many heavy rains there.

Without trees and grass,heavy rains would wash away the rich surface soil which is so essential for agriculture.The result is that the land becomes useless and unproductive.

There are many desert areas in the world,which used to be very rich and fertile areas.But people in ancient times cut down trees indiscriminately and no new trees were planted.When strong winds came,they blew away the rich surface soil and for this reason the land was ruined into useless deserts where nothing could grow.
