Urban Sprawl: Phoenix

Most people think of urban sprawl as the construction of roads and buildings at a rate that exceeds population growth. Phoenix, Arizona, however, offers a contrasting model of sprawl. Its metropolitan area has grown more than 300 percent in recent decades, but its population has grown even faster. Since the mid-1980's, the city's population density has increased as people continue to move to the region even as the urban area's boundaries have grown more slowly. This trend is by necessity, since the water supply cannot feed an ever-expanding metropolitan area.

Bronx River Restoration

In the 1600's, New York City's Bronx River was a drinking water source and a sylvan haven for beaver, oysters, and herring. It became blighted as urbanization progressed, reincarnating as an industrial power source, an open sewer, and a garbage dump. Today, landscape ecologists are reconstructing the waterway's ecological history as a reference point for its restoration effort. Watch conservation teams coax new life into the Bronx River as they restock it with native fish, lay down oyster beds, and remove invasive species along its shores.
