Pollution is the biggest challenges of today’s human. The world is fighting today with the two main challenges, that is, air pollution and water pollution. We, the humans, know that air and water are our most basic needs, still, these are ignored because of their free availability. The time has come when people are suffering from diseases caused to unclean air we breathe and polluted water we drink daily.
Every year we see that India and Indian cities top the list of having the most polluted air in the world. Same applies to water pollution. We have the river Ganges which fulfills the basic needs and irrigational needs of a large part of India.
