In 2026, NumbersUSA is revisiting the subject of sprawl in California. Preliminary analysis suggests 93% of sprawl in recent decades in the state has been caused by immigration-driven population growth.
Without immigration-reduction, population growth and sprawl will continue to drive biodiversity losses and degrade Chesapeake Bay’s water quality, commercial fisheries, and overall ecological health.
As more people move into the Chesapeake Bay region, development has turned forests, farms and other landscapes into subdivisions, shopping centers and parking lots. As more people have moved in, the health of the Bay has, inevitably, declined.
Over the past twenty-five years, NumbersUSA has published numerous scientific reports on the causes and consequences of sprawl in the United States. Our most recent study quantifies ecological decline in the Chesapeake Bay and its watershed over the past three decades. Looking forward, we explore a path toward ecological sustainability centered on stabilizing the region’s population through reduced immigration.
If federal immigration policies driving national population growth continue, California’s environment and residents’ quality of life will pay an ever higher price. There can be no sustainability in a context of ever growing human populations.
Pioneering primatologist Dr. Jane Goodall passed away last week at the age of 91. She was a champion of chimpanzees, conservation … and population activism.
Legendary wilderness warrior, rewilding pioneer, and NumbersUSA friend Dave Foreman died this past September 19 at the age of 75 in Albuquerque, New Mexico, succumbing to an illness called interstitial lung disease. With his death, Mother Earth lost a diehard defender and the United States a formidable fighter for rational population and immigration policies cognizant … Continued
Around the world, those of us who have, for half a century and more, questioned and challenged the reining dogma of “growthmania” — the widespread delusion that infinite population and economic growth is possible in a finite ecosphere — are in mourning. It is as if, as Herman’s longtime colleague and admirer William E. Rees … Continued
I have had the good fortune to experience the charms of both the Tar Heel State and the Palmetto State. For those Westerners who may never have ventured east of the Mississippi River, I’m referring to North Carolina and South Carolina. In the former, I have backpacked the Appalachian Trail from Newfound Gap in the … Continued
