‘Water is another name of life’- this universal truth is known by all. But do you know that nearly 80% of human body consists of water and thus water contributes a huge part of human existence? Not only for drinking, but you need water in your day to day life for various other purpose too, starting from cooking, cleaning, washing, bathing etc. Water has no substitute and hence water is precious. But unfortunately this valuable natural resource is getting polluted day by day due to our unhealthy activities and this needs to be checked on a priority basis.
