The amount of drinking water is limited on our earth, and the population on the planet is increasing like anything, especially in highly populated countries like India and china. So it has become hard to provide safe and clean water to drink in such countries, people need to do high level of filtration of the water before drinking it, Still there are many people around the world who has very careless attitude about the importance of water. The time has come where we will have to take care of every drop of water and not to waste it.
People are least informed about the purity of water which is safe for them to drink, they just drink it after an ordinary filtration method and that’s not scientifically safe and it is going on in most of the part of the world and thus it’s happening this way.
