Water Conservation
Water is the source of life for human being. Water feeds us, water keeps us alive. Water is the very important part of human life, without water we can’t live in this world. Water in this world is constant in quantity, it revolves in three states, liquid, solid and vapor. Rain is the main source of water for us, and sea is the main source of rain. In the summer the sea water evaporates and accumulates in the clouds. When clouds burst, the water falls as rain on us. This is a very simple definition, actual a science involves in the process.
We don’t need to tell anybody what is the importance of water; everybody knows how important water is for them. If you want to know the thirst of water, don’t drink water for few hours only. You can feel how a desert living peoples are feeling for the water. Our body consists of 80% water. Water is the main part of the cellular system and it is used in all chemical reactions in human body. Water is made up of two hydrogen molecules and one oxygen molecule. It is also denoted as H2O.
We have 2/3rd part of world covered by water, but still we see, read about shortage of water, why? 2/3rd part of world which is water is mainly sea water and it is not drinkable for human body. Drinking water we get through rain, or found in rivers, lakes is very less compared to the sea water. The cost associated with the converting the sea water to drinking water is much more than the gain. We call the condition as shortage of water, because if we continue polluting the water like this, we would have a situation when the drinking water will be very less than our needs.
