Pollution can cause a lot of health problems so unless we are aware and make sure that our surroundings are clean there is bound to be problems..Vehicular emmisions and chemical waste including plastic is the biggest problem we face now..
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
Why you should make the people understand? Air pollution doesn't affect a single person. It affects all of us who are subjected to air pollution.
Because still there are people who don't know the ways which may help in making our surrounding less air polluted. And one of the best thing we can do is to grow trees.
