Over the last 25 years, NumbersUSA has published reports on sprawl in the U.S., with a focus on Chesapeake Bay’s ecological decline. The bay, America’s largest estuary, suffers due to pollution from urban and agricultural runoff. Recent reports indicate a slight improvement in conditions, yet the bay’s health is still rated poorly.
Population growth in the Chesapeake Bay watershed surged from 16 million in 1982 to 22 million in 2017, causing significant land conversion for development, with 58% of this sprawl linked to population increase. This has led to pollution and habitat loss, affecting wildlife and water quality.
Despite evidence, many environmental organizations overlook population growth as a primary factor in ecological decline. NumbersUSA argues that addressing population issues could be crucial for effective environmental conservation efforts in the region.
