How does this sound for a vacation: A fun-filled trip to Chernobyl, the site of one of the world's worst nuclear accidents? Or how about a boat cruise down the Yamuna River, India's most polluted river? Don't leave out possible trips to the Great Pacific Garbage Patch or a visit to the site of the most devastating deforestation in the rainforest near the Amazon?To Andrew Blackwell, these sounded like delightful trips. He traveled to all of these and more spots noted for being on lists for the World's Most Polluted Places and wrote about them in the book. Blackwell actually seemed to relish visiting these places and his enthusiasm for these trips echoes throughout the book. Not really where I'd like to spend ten days of R&R, I think. Though I will say Blackwell never had to worry about standing in long lines or trying to find an available hotel room.
