Atlas of the changing environment

The UN Environment Programme released this really amazing collection of presentations about global environmental change called "One Planet, One People: Atlas of the Changing Environment". The terrific collection of satellite imagery, aerial photos and figures depicting of environmental change can be viewed on the website (and downloaded free of charge).

I strongly recommend taking a look. My favourites are "Water and Lakes" (no surpise) with the before and after images from places like Lake Chad, the Dead Sea and the Marshlands in Iraq, the "North America" slideshow, with images depicting the sprawl of Las Vegas, oil drilling near Fort McMurray, Alberta (the tar sands) and what snow geese have done to the shoreline of Hudson's Bay, and the "Latin America" slideshow depicting the extent of deforestation in central and South America.
