Agreed. In addition I think people overestimate the CO2 produced by burning plastic. A plastic shopping bag is 6-8 grammes. Burning it produces about as much CO2 as driving a car 200 yards. If you pick a supermarket one mile further from your house because they have a better policy on plastic bags then the environment loses.
