Water covers about 75 per cent of our planet so it appears plentiful. However, 97 per cent of that water is salty ocean water which we cannot drink. Of the 3 per cent that is fresh water most is frozen in glaciers and polar ice caps. As a result, only 1 per cent of the Earth's water may be available for drinking. Moreover, the Earth water supply is fixed not new water is being made. WE have the same amount of water now as there was when the earth was created. This is the water we have and we must preserve its quality. Water is the foundation of food and life. Next to air. Water is our most precious resource. WE cannot live without water. C. V Raman has rightly said Man has rightly said Man has through the ages sought in vain for the imaginary elixir of life the divine amrita a draught of which was thought to confer immortality. But the true elixir of life lies near to our hands. For its is commonest of all liquids plain water plain water. That is why most of our civilizations and important cites grew on the banks of big rivers only. Our ancient religious texts and epics give a good insight unto the water storage and conservation systems that prevailed in those days. The Indus Valley Civilization that flourished along the banks of the river Indus and other parts of western and northern India about 5,000 years ago, had one of the most sophisticated urban water supply and sewage systems in the world. The fact that the people were well acquainted with hygiene can be seen from the covered drains running beneath the streets of the ruins at both Mohenjodaro and Harappa. In the forests water seeps gently into the ground as vegetation breaks the flow of water. This groundwater in turn feeds wells, lakes and rivers. Protecting forests means protecting water catchments. In ancient India, people believed that forests were the mothers of rivers and worshipped the sources of these water bodies. Water is a source of beauty and joy. It adds to the beauty of nature. It may be a little stream trickling down the rocks or a waterfall big or small it is a joy to the eyes and a freshening breath of beauty to the mid, Brooks and rivers dancing down the hills on their majestic journey to the sea in their serpentine ways add a touch of novelty to the scene. Small tanks lakes or big oceans earn rich tributes from sensitive poets. A great writer wrote: Water in a landscape may be compared to the eyes in a human face. It reflects the mood of the hour. Being bright and gay when the sun shines turning to dark and gloomy when the sky is overcast.
