100 Alien InvadersHardcover, 18 October 2011

100 Alien Invaders exposes one of the greatest threats to the planet after climate change and overpopulation. Animals and plants are perfectly harmless in their native areas, but become a menace when they colonize new territories--often out-competing native species and, in some instances, drastically affecting the ecology. What's more, it is humankind that is largely responsible. Some species, such as killer bees and cane toads, are obvious terrors. Others, such as the water hyacinth, pose a more insidious threat. Read this book and you'll never look at house sparrows or hedgehogs in the same way again. 100 Alien Invaders is a warts-and-all exposé of 100 of the most destructive alien species on the planet.
