I just ordered a book entitled by Alan Weisman, an "enthralling tour of the world of tomorrow [which] explores what little will remain of ancient times while anticipating, often poetically, what a planet without us would be like."
The book and its author have been getting a lot of press lately, and not just because envisioning the future of the planet sans humanity is a fascinating topic for a book. Weisman even recently.
Even if you're not inclined to buy the book, has a lot of cool multimedia that you can mess around with, including two videos: the first is a video slideshow of New York City without humans over the course of 15,000 years (I am immediately thinking about ); and the second is an animation entitled .
Anyway, if you're interested in learning more about the book, . I hope to write a review when I am finished with it as well.
