Trees and Their Uses
Trees are great friends to man. Man needs Oxygen for living. Trees absorb the carbon-di-oxide and give him oxygen back. Air-pollution is a great danger to mankind today. Trees help us in checking air-pollution. They also cause rainfall by inviting rain-bearing-clouds. It is why there is much rainfall in forest. Rainfall helps agriculture and the growth of vegetation. We also get food, fruits, flowers, timber, fuel-wood and coal from trees. A large number of industries such as paper, match, leather and rubber get raw materials from trees. They check the free flow of water and save us from floods and soil erosion. They also halt the spread of deserts.
