This is an interesting gallery before and after satellite photos of mankind’s impact on the environment. They come from a new book called Fragile Earth and are pretty interesting. It can be quite sobering to see what a real impact we are having on our environments

This one shows a rainforest ecosystem around the Iguacu falls in South America getting nailed. Feb 1973 to May 2003

This is Lake Chad in Africa disappearing between 1972 and 1987 – largely due to irrigation projects. Things have actually gotten worse since the second photo was taken… I have blogged on this one before.

Finally, this is jungle in Bolivia getting turned into a major agricultural area.
