RE: Some basic Facts About Water, You need to know What are you Drinking?

Although to in earth more than 70% is water but only 3% of them was drinkable for us from the past. Most of the water is marine water and we can't use it for our daily use and for drinking.
Unfortunately those 3% of water is also getting polluted in the current time and it's alarming for us. In the future we may face a terrible situation for it.
