Air is very much important to all of us. Especially pure air, nowadays our air is polluted a lot. Smoke coming out from the vehicle, brick industries and cigarette, it polluted a lot as well as helps in the production of other harmful gases. this directly effeted on human heath. So we should make our air as clear as blue sky by using less vehicle more bicycle. I always go to my school by my bicyle too also we should banned cigarette from this world. 

Thank u
