We must make proper sewage system. Garbage should be thrown in bins. We must make people aware about the harmful effects of pollution.
We should tell people the harms from pollution. a great man of our India Sir. Zakir Hussain said that "you can not expect people to follow the rules just because you have said to follow them, but you should also follow the rules which you expect from them to follow." So start doing things for avoiding pollution yourself to attract people and to make them aware about harms from pollution. Thank You!
