The study of endangered animal species is an essential component of the elementary science curriculum, as well as a valuable conservation topic for younger readers to familiarize themselves with. The titles in this series cover the major animal groups and highlight species that are endangered in some way. Readers learn about the ramifications of human actions, such as creating and using fossils fuels, and what each of us can do to lessen the effects of global warming and climate change. Each book includes information on at least one extinct species–including primary source images–to help drive home the urgency of conservation and animal welfare. Readers will also read success stories to demonstrate that people can help save animal species from extinction.
