I have a 17 and 16 year old. My daughter (17) has listen to me tell her about the chemicals she puts in and on her body, I have organic shampoos and such in the shower, she won't use them. I do have to say I did finally find a toothpaste she doesn't mind, but it was a struggle. My son (16) just can't grasp the concept of the food scraps to the compost pile. Is it laziness? I don't know, does anyone else have any problems with getting your teenagers into the "green" movement?
