True in states near the Himalayas like Uttarakhand, Himachal Pradesh the water is drinkable and pure.

Majority of grocery shops hand out ultra thin plastic bags which will choke the rivers and environment. But important thing is public attitude. The attitude now is to collect as many of these bags as one can. So there you go. If the municipal corporation enforces a separate charge or ban, things will shape up. I do use a reusable bag. I&#x27;ve stopped using plastic bags.
