Forests are indispensable to mankind. They provide us with wood, raw materials; prevent floods and soil erosion; increase underground water supply and humidity of air; provide an abode for the wildlife, check air pollution, etc. On a sunny day a large elm tree gives off vapor which is equivalent to 1500 gallons of water. Annual world production of forest products exceeds US $ 150 billion, thus playing a vital role in the economy of a nation. According to a UN report, rain forests have been destroyed to a large extent. Man has mercilessly chopped off trees without paying any attention to the destruction he is causing to his own life and future. Hillsides have been stripped off its vegetation cover in the Himalayas, which has become a major cause for the earthquakes, avalanches, and landslides. Deforestation not only diminishes the natural beauty of any place but also upsets the ecological balance of that place. It is believed that the Thar Desert is a man-made desert. Yes!
