It's a pleasure to know that Bageshwar admin has banned polythene usage. Even Almora and other distt admin has banned it.
If I am not wrong Pithoragarh was the first distt in kumaon to impose ban nearly 8-10 yrs ago and the initiative was taken by the public.That time I visited there and felt really proud that other distt.s will follow suit and uttarakhand will get rid of this menace.
But,come 2012 and it again is being used, the shopkeepers from the plains bring it in huge quantities and use/sell it under the nose of admin. Same has started in Almora.
So the point is, until the state govt doesn't impose blanket ban on its usage, and frame strict law, its very hard to get rid of it.
