Like or not, Doing things better for the environment helps everyone in the long run and if you don’t believe it, it doesn’t hurt either. Do One Green Thing is a book which gives ideas on how to save the Earth through simple choices.  There are chapters on: food & drink, healthy homes, transportation, personal care and so forth. I recommend taking a look at the book and finding areas you would like to work on and see how easy it is to help change the World with very simple steps.
