Scientists define a desert as a region that each year loses more water into the air as water vapor than it receives as precipitation int he form of rain, snow, sleet, hail, dew, or frost. Deserts may seem hostile to life, but most natural deserts are home to plants and animals that have adapted to flourish in the harsh environment. The expansion of deserts due to pollution or unsustainable farming practices presents a major ecological challenge for modern societies.
The World's Biomes series provides information on five of the most important large ecological systems in the world today: deserts, grasslands, oceans, rainforests, and wetlands. Each book int he series describes the climate, geology, vegetation, and animal life found in a particular biome, as well as the modern threats and what people can do about them.
