Many hill stations (Like Shimla and Manali) have banned plastic bags. And that is good. Otherwise the amount of plastic that we can throw around is just amazing. But then if we will not throw plastic bags then we will throw chips foils and plastic bottles! I persoanlly carry any rubbish that I canot dispose properly till I find a dustbin or till I am back to the hotel room. And I have seen many others do so too. But for every one person who does not litter, I have seen ten who would throw the chips foils anywhere. Yeah, I can see this is turning into a rant now. And of all things, when trekking, I have seen many small villages completely strewen with plastic, it is not jut the citywalahs.
