Human actions affect the world around us. From pollution in the oceans to deforestation, many of these actions are harmful. In this book a friendly guide takes readers through what happens to habitats when they are affected by harmful activities--animals become endangered, ecosystems fall out of balance, and Earth is cared for. There's a bright side: In this book, readers learn all about what conservation is in age-appropriate detail as well as ways they may be able to help habitats in danger.
