We can solve this problem – and help level the economic playing field – by prohibiting both plastic bags and paper bags. We should only be allowed to buy as much as we can carry in our arms. That should also help with the meat problem. The less meat we can carry, the less meat we eat, and that means fewer cows will be destroying the planet with their emissions. But to make this work, we must also ban shopping carts. The wheels are made of rubber and using them just adds to our dependence on foreign oil.
