A lot of places outside the USA, already don't offer plastic bags and force you to bring your own bag or make you buy one if you don't have it.
That's what we do in England. We also have collection points at supermarkets to recycle the plastic carrier bags people buy. I agree with creating less waste that takes 500 years to biodegrade and is harming our sea life.
The amount of dead whales, dolphins and turtles that have been washed up with stomachs full of plastic is shocking.
It's not like it's difficult to take reusable bags shopping, I keep them in my car. I'm an intelligent life form, I can cope with that.
