Plastic bags use 70% less energy to produce, they generate 80% less waste, they take 91% less energy to recycle, and they generate 79% less greenhouse gas.  Use reusable sacks, reuse bags, or at least recycle at the supermarket.  Dishes or paper plates?  Use dishes and wash them in the dishwasher.  Even with an extra rinse cycle, the dishwasher uses 3 X less water than hand-washing or pre-rinsing!  Paper plates require trees to be cut down and will end up in landfills.
