Antarctica, the earth's southernmost continent, was virtually untouched by humans until the nineteenth century. Many famous explorers journeyed (and often died) there in the hope of discovering a land that always seemed out of reach. This book introduces readers to this desert--yes, desert --continent that holds about 90 percent of the world's ice; showcases some of the 200 species that call Antarctica home, including the emperor penguin; and discusses environmental dangers to the continent, underscoring how what happens to Antarctica affects the entire world.
