Indian railways bans plastic, gives new hope to threatened potters' trade (Channelnewsasia.com)

Laloo Prasad Yadav, the new railways minister, has banned plastic cups on Indian railways. The canteen in the parliament has already removed plastic cups.

The earthenware cups, called "kulhars", are bio-degradable and are cheaper than the plastic cups.

What if a big coporation steps in this business and makes the cups even cheaper? The trickle-down benefit of this move will be lost even if the environmental benefits remain.
