Humans have found ways to adapt and survive in all of Earth's many diverse habitats. This colorful series shows how people use the resources around them to build homes, grow food, and do work that suits their environment and climate, from the sweltering Sahara desert to the freezing arctic tundra. A link printed inside each book gives readers access to Crabtree Plus, a website featuring supplemental digital content, including interactive activities that reinforce and extend key series' concepts. Free downloadable Teacher's Guide available.
