BR - I wasn't trying to change your gender - the "he" I was referring to was Kurt w/ his talk of the chilly empty homes being photographed!
Cloth bags for the grocery would be a great thing to see - especially if they could just get a new holder to make bagging easier. They already have recycling for the plastic bags.
I love how someone starting a thread wanting fun tips on conservation marks all contributors as granola crunchers and non-shavers! Sorry to blow your stereotype 6thGen, but I not only shave, I eat meat, use AC to make myself comfy and drive a car. Making sustainable choices as a consumer isn't limited to those in tie-dye!
When I'm in the checkout line I usually have nothing to do so holding a bag open might be an idea.
A friend of mine likes to call himself a conservative tree hugger. As Maher pointed out the other night, "wouldn't you think conservatives would want to conserve"?
