I do a lot of the “usual” green things. I recycle. I compost. I shop second-hand. I carry reusable grocery bags and a stainless steel water bottle. I walk my daughter to kindergarten and back every day. I turn down my thermostat and put on a sweater.

But there is an obstacle to my green efforts – much of the time, I don’t want to be inconvenienced by going green. I bring my reusable grocery bags when I go grocery shopping, but if I occasionally forget, I don’t sweat it. I drink tap water, but when I forget my water bottle at home, I sometimes buy water in a plastic bottle.
