Can you stay alive without water if you think you can't then its high time you should stop wasting it and also take care that others don't waste the same.
Recently saw a documentary about how much water is important to is and the wastage that is done everyday.
Survey says that we waste 40% of water that means we use water more than our requirement. Some people wash the same cloth twice to thrice a day, some people take 4 times bath a day and the most astonishing part some of the taps can't be closed causing to waste water unnecessarily.
Its high time we realize that water is life and nature is not going to compensate our wastage.
