Publisher's Synopsis
It's difficult to imagine a world without animals such as gray wolves, polar bears, or bees. In some cases, it may seem as if not much would change if an entire species of animals, such as corals or oysters, were to disappear. But readers of this series will find out just how untrue that is. With content centering on important life science concepts such as keystone species and ecosystems, these books investigate what would happen if the animals were to disappear. With the help of colorful photographs and gripping text, each book considers a different animal's impact on its environment.
