While I wished the author had been even MORE thorough on how the average person can help the environment (I admit I really wanted a checklist, sort of a "Don't think you can make a difference? Here's HOW you can make a HUGE difference" list) he did give several good tips on how the everyday person can make a difference towards helping our environment. And he freely admits that most people aren't going to make radical alterations in their lifestyle, so the tips he gives aren't crazy, out-there, "live in a hut and only eat nuts" kind of tips. Plus while he spells out how serious the problems with the environment are, he's still optimistic, that it IS within our ability to change things, right now. Plus it's a short book, and a very easy read.
