From The New York Times:

In its struggle to make New York more green, the Bloomberg administration has tried discouraging people from using plastic bags. It has taken out ads beseeching residents to use cloth bags and set up recycling bins for plastic bags at supermarkets.

But now the carrots have been put away, and the stick is out: Mayor Michael R. Bloomberg has called for charging shoppers 6 cents for every plastic bag needed at the register.

Why am I not surprised?
