Each one of us can contribute to saving the mother earth from getting polluted in small ways. For example I have come across people - friends, family , acquaintances - who after eating a bag of chips or wafers just tend to throw away the empty packets . What I try at such times is ask them to throw the packets in the dustbin. Incase you cannot sight a dustbin I ask them to keep them inside their bags and throw it when they find a dustbin. Incase they say leave it casually we can ask them to give the packet to you and then you can throw it later. These are very small thing but next time , they will think about it and may be do the same thing. Good going. I hope others find inspirations from you guys and take more initiatives.
