The plastic bag ban is spreading.
I posted last week about how California has been leading the charge on banning and taxing for bags. Check out this interactive map of bans/taxes I featured in that post:

TreeHugger reports that Los Angeles recently banned plastic bag distribution at large retailers. San Francisco was one of the first cities in the US to place a tax on bags.
For another interactive map of the history of bans/taxes, from Earth Policy Institute, click-through the photo.

But it’s not only plastic bags – as you can see on the maps. Here in Boulder, I get charged 10 cents for a paper bag at Trader Joe’s (only when I forget my reusable ones!).
So, the ban and taxes have come a long way since I did my plastic bag project in 2011 and since my last plastic bag update.
Many towns and cities are considering plastic bag legislation – and I would love to see it go through!
