Polythene bags are ubiquitous these days but the worrying fact is that these bags are very harmful. The main disadvantage of polythene bag is that is a non-biodegradable product and it causes harm to humans, plants as well as animals. These days many governments across the world have put a ban on use of polythene bags. I think that banning the use of polythene bags is not the only solution and we should try to teach people not to use polythene bags. Can you share experiences where people have been asked to stop use of polythene bags?
