Suppose for some reason your family gets only one bucket of water everyday for a week. We would not be able to cook, clean utensils, wash clothes or bath and other activities. Apart from drinking, there are so many activities for which we use water.
We all depend on the same vital substance water, diverse by its nature, it is solid, vapour and liquid. It is in the air, on the earth surface and within the ground ever-changing and giving shape to a dramatic range of natural ecosystems.
For the earth’s inhabitants, diversity of the resource also means great disparities in well being and development . As we degrade the quality of our water and modify the natural ecosystems on which people and life depend, we also threaten our own survival.
