Increasingly people are moving from rural to urban areas which is broadening and expanding the footprint of our cities. The year 2008 marked the first time in human history that the majority of people lived in urban places. Over 1.5 million people are added to our population each week, and the majority of this growth is absorbed into cities. This great urban migration has two major consequences for natural communities. First, the strain that people place on natural resources is increasingly concentrated in and around urbanized centers. Second, for the majority of humans worldwide, the city has become the primary context for interacting with and experiencing nature and wildlife.
