SF has supposedly banned plastic bags for some time, however you can still be handed your loot in a plastic bag in nearly every little corner market, as well as any restaurant where you are taking something to go.<p>What i think SF should require, as opposed to banning plastic, is to require that instead corn/vegetable based bags should be used.<p>Plastic bags offer great convenience at a pretty significatant environmental cost.<p>For pretty much 100% of single-use, temporary applications, we should be using vegetable based materials.<p>Look at how much plastic is used simply as packaging for even single-use products; plastic covers on straws, most food is all wrapped in plastic.<p>We should be looking at reducing these types of packaging materials that simply gets thrown away.
