Short note on water an elixir of life
Answers
Water is quite aptly called “elixir of life”. 71% of earth is covered in water (hence the name blue planet) and up to 60% of human body is made up of water. Most importantly it is used by all terrestrial animals to drink in order to provide essential minerals for the body's nourishment
Water, oxygen, sunlight, fire and earth are the five most important elements of life on earth. And amazingly the earth, by luck, has just the correct proportion of each of these five life enabling elements. Earth is neither too hot nor too cold, neither all water nor all gas. It is at a correct distance from the sun enabling just enough heat during the daytime. It has a mechanism to supply oxygen (plants) to humans and other living beings. And it has fertile soil for tress to grow.
Importance of water
Water is of such an importance in our life that John F. Kennedy once said:
“Anyone who can solve the problems of water is worthy of two Nobel prizes — oWater is quite aptly called “elixir of life”. 71% of earth is covered in water (hence the name blue planet) and up to 60% of human body is made up of water. Most importantly it is used by all terrestrial animals to drink in order to provide essential minerals for the body’s nourishment. It is also used conventionally to irrigate crops, to boil and make food, to wash clothes, utensils among other things, as a coolant and raw material in industries, to put out fires, in swimming pools and generation of hydroelectricity.ne for peace and one for science.”
In terms of usage volume, agriculture contributes to approximately 70% of the global water demand, with industry and domestic demand at 20% and 10% respectively. In domestic usage, drinking and cooking only contribute to 10% of our daily water usage with bath taking the lions share (at an average of 55 liters per day).
