Species That Threaten Our World
Jan 29, 2016CMLibrary_rkimray rated this title 4 out of 5 stars
Alien invaders are taking over our world! The natural world, that is. This book thoughtfully describes the where, when and how of over two dozen invading species, including plants, animals, bacteria and viruses. With its bright, colorful illustrations, this book is a great introduction to the many sides of a complex environmental topic. It also provides suggestions for how we each can become an "ecoguardian" to help prevent future alien invasions.
