Environmental Defense has just put out its new 2007 Summer Reading List, which includes a lot of oldies back to Silent Spring. They want to know which has been the most influential book on the environment. Use the list as inspiration, and vote in their list.
Certainly The Silent Spring was an enormous jolt in its time. I think now, Al Gore's movie An Inconvenient Truth provided the biggest earthquake recently in environmental awareness.
I was so inspired by last year's reading list that I took it over last summer and added a few more to it. I thank their staffers for their inspiration!
I have a little Squidoo blog heifer/bonsol, which has links to a lot of these books (way at the bottom.) If you happen to buy one through those links, a little contribution is made to Heifer International.
