Description: Earth's environments are constantly changing and have been since Earth formed. However, Earth has changed drastically since the dawn of the earliest human relatives. In the last twenty years or so, scientists have found that human activity has put three-quarters of Earth's land surface under pressure. This set explores how humans have impacted a number of environments and how these places might look if humans didn't exist there. Suggested conservation efforts show readers that hope isn't lost for these parts of Earth, and that they can help make these environments healthy once again. Features include: Full-color photographs and primary sources aid student comprehension. Supports the Next Generation Science Standards by introducing students to the methods by which humans understand the natural world and how they interact with their environments. Incorporates STEM-related topics to enhance readers' STEM knowledge.
