Humans have used resources from their environment for food and shelter for millions of years. Over time, however, human activities have extensively impacted Earth's ecosystems. Rain forests are one of a number of ecosystems on Earth that have been negatively affected by human activities. This book explores the different ways humans have impacted the plants and animals that call rain forest environments home. Full-color photographs depict harmful human activities and conservation efforts while fact boxes and sidebars provide readers with additional information about how rain forest environments have changed since the dawn of the human race.
