Land,Soil, Water, Natural Vegetation and Wildlife Resources

Water is a vital renewable natural resource. Three-fourth’s of the earth’s surface is covered with water. It is therefore appropriately called the ‘water planet’. It was in the primitive oceans that life began almost 3.5 billion years back. Even today, the oceans cover two-thirds of the earth’s surface and support a rich
