The geography and geology of lakes and rivers is a fascinating subject. From plankton to larger fishes and wildlife, rivers and lakes are rich with biodiversity. The earliest civilizations were based around rivers, including the Nile, Tigris and Euphrates, and Indus and Huang Ho valleys. Illustrating the physical geography, hydrology, ecology, and human use of these areas, "Lakes and Rivers" provides an excellent overview of the past, present, and future of these habitats. This volume concludes with a discussion of threats to rivers and lakes, such as overharvesting, effects of damming, pollution, and climate change, as well as ways to manage and protect these habitats.
