Abstract

Abstract

En 中文
The rapid urbanization of the world's population (accompanied by the rise of megacities) and the profound growth in the scale of impacts on the natural environment were two dominant trends of the twentieth century. Today over 3 billion people, nearly one‐half the human population, live in urban areas (United Nations 2004). Humans have altered the composition of the atmosphere, contributing to global climate change, have changed land cover over a large proportion of the earth's surface, and have contributed to a dramatic rise in the rate of species extinction.
