Why does water need conservation even though large oceans surround the land masses?
Water is one of the basic necessities of life. The availability of water is an important factor that decides the sustainability of life in a region. Water occupies a very large area of the earth’s surface. of the water on planet earth is found in seas and oceans as saline water and unavailable for human consumption because bodies of terrestrial life-forms cannot tolerate high amounts of dissolved salts present in saline water.
Only of the total water resources of the world consists of freshwater. The majority of it (about \(2\)%) is found frozen in the ice-caps at the two poles and on snow-covered mountains. The remaining (only about \(0.6\)% of the total) is available to support terrestrial life. The majority () of this freshwater is found underground as groundwater and only occurs as surface water. Since a limited amount of freshwater is available as a renewable source through the water cycle and its distribution is also limited, water conservation is a prime requirement.
