The developed world’s worst habit may be the waste of energy in all of its forms; caloric, solar, mental, physical and industrial. We’re only now beginning to comprehend the amount of irreparable damage our wastefulness has done to mankind and the planet. We’ve wiped out entire species and habitats, created and fought racial and sexual inequality, bled the planet’s carbon reserves dry, grown overweight, diseased and apathetic. I haven’t spoken to a twenty-something American who isn’t concerned about being “green” or saving money, and yet… as so often happens… they forget the small steps it takes to do either.
