Without the plants on our planet the evolution of life here would have been impossible. Plants were instrumental in the supply of oxygen in the atmosphere. Thus the stage was set for Adam and Eve. And now there are about five billion people living on the earth. So we must acknowledge the importance of plants in our life. The trees are an integral species of the plants genus in existence on mother earth. The trees have played a very important role in the past and continue to play even now. We are indebted to trees for soil and climate as well as for their direct contribution to our homes to hospitals and to our factories.

          In the quite amazing the ways in which trees support life. Fuel–wood building materials and a wide range of food and medicines and other products and obtained from forests. Approximately trees range across 30 per cent of the earth’s surface. They produce and sustain large stocks of biomass and nurture the greatest number of plant and animals species.

           Forests play a significant role in the recycling of nitrogen, carbon and oxygen. They affect climate conditions such as rainfall and temperature. Moreover, they are the fountain heads of rivers. They play the additional role of the largest gene reservoirs on the planet earth. They are the site for discuss and development of new species.

          Planets the greatest gift the forests have given us is wood. It is one of the first raw materials that we used. It quite possibly could be our last. Almost every major industry is dependent upon the forest and its products at one stage or another. A house wall built of wood requires 20 per cent less energy for heating and 30 per cent less for cooling than a wall of any other construction material. Moreover, wood provides hardboard, play board, veneer, chipboard, particle board which we use for furnishing our homes and offices.
