ABSTRACT
Water is the central element essential to life as we know it. e human body is from 50 to 65 per cent water, while over 70 per cent of planet earth’s surface is aquatic. In fact, the oceans constitute more than 97 per cent of the world’s water, making earth when seen from space our solar system’s ‘Blue Planet’. Another 2 per cent of the planetary water is frozen into the ice caps of Greenland and Antarctica. What this means is that our freshwater lakes, rivers and underground water sources producing the water we drink and use for our bodily sustenance and health, as well as to irrigate the food crops on which we depend, is not more than 1 per cent of the world’s total water supply.
