People's effect on the Earth

The United Nations Environment Programme put out a book last year entitled "One Planet, Many People," which is available online and in several of the libraries on campus. This book contains a number of images showing the effect of mankind on several hotspots across the globe. I wanted to highlight the new Interactive Maps feature that allows you to view comparison images on various locations around the world from Lake Chad in Africa to Las Vegas here in the United States. For those of you without Google Earth installed (it is free), you can check out the images by date and location as well.
