内容简介：
The equator is an imaginary line, equidistant from the North and South Poles, that divides Earth into the Northern and Southern Hemispheres. This fascinating look at the thirteen countries that fall on this imaginary line provides insight into the savannas, tropical rain forests, woodlands, and high-mountain environments that are all considered equatorial lands. Using gorgeous full-color photos, Life on the Equator discusses the four layers of the rain forest and identifies plant and animal life--which can include 300 kinds of trees, 1,600 species of birds, and about 1 million insects--that have adapted to life in the region.
