Usborne's Living World Encyclopedia provides a great introduction into the amazing world of nature. The first section of the book covers living things and their environments. This section serves to present general information in the areas of: the history of the Earth, environments, cycles in nature, seasonal changes, and long-term changes. The remaining sections explore animals and plants by environment. Plants typical to the environment are introduced, and the lifestyles of animals (how they find food, attract mates, escape enemies, and adapt to varying habitats and climates) are examined. Environments covered include: seas and oceans, islands, grasslands, forests, deserts, polar regions, mountains, rivers and lakes, and rain forests. Additional sections on people and endangered species are included.
