Aliens from Earth
Aliens are everywhere!
Batten introduces readers to the serious and ongoing environmental problems caused by invasive plant and animal species. Describing various examples—from the accidental release of the gypsy moth into the United States to the deliberate introduction of rabbits to Australia—the text shows how these foreign intrusions have disturbed the delicate balance of local ecosystems. Back matter includes a glossary and list of ideas that provide more information and ways to minimize human impact on local environments.
