From killer toads, feral felines, and brown tree snakes to multiple invaders in Lake Victoria and the Great Lakes, Alien Invaders focuses on wave after wave of invaders that affect our ecosystems and the side-effects of climate change and modern global travel on our world today. Environmentalists and coauthors Jane Drake and Ann Love present the concepts of endangered species and biodiversity in this informative look at alien invaders and how they impact our world. From the days of sailing ships and shipboard rats to the fungus that sparked the Irish potato famine to the beautiful but deadly purple loosestrife strangling native wetlands, they examine extinctions and endangerments directly attributable to these alien invaders. Learn where the invaders originated, how they traveled, where they settled, what they displaced, why the invaded natural system was vulnerable, and what can be done. Kids can determine if they themselves are invaders or savers and how they can help. This exploration of a timely topic, coupled with the lively detailed illustrations of Toronto artist Mark Thurman, inspire kids and adults alike to be more observant and protective of our natural world.
