World Book Ecology: Life in the Cities
A city is a community where thousands—or even millions—of people live and work. Cities are the world's most crowded places. Cities were first built over 10,000 years ago; now they have been built on every continent except Antarctica. Learn all about cities as World Book Ecology presents Life in the Cities; explore the ecology, cultures and living environment in the cities around the world.
