Water is very necessary to people and other living things. Without water, people, animals and plants cannot live. And if there were no plants, water would run off after it rains; and this would cause a lot of Hoods. But nature has many ways of conserving and controlling water. Water can be held on the land by planting vegetation. Forests and grass should be planted where there are no natural growths. Dams built across rivers help hold back the water. Reservoirs behind the dams store water during wet seasons for use in dry seasons. Dams help prevent floods by controlling the flow of water.
