American Forests

Satellite imagery of deforestation in urban areas (Link to report) This page contains reports for major urban areas across the US.  Satellite photos are inside individual reports.  The image below, used with permission, shows deforestation in and around  the Portland, Oregon metropolitan area between 1972 and 2000.  This large-scale loss of forest contributes  to global warming, sewage overflows into the Willamette River, and increased drought.
