California’s population has doubled over the past five decades,” said Leon Kolankiewicz, an environmental planner and the report’s lead author. “That growth naturally led to sprawl, as developers constructed new homes, roads, and office parks to meet demand. In fact, our analysis shows that population growth drove 91% of the total loss of open land.
“How big do we want to be?” Mass immigration is the determining factor in the size of our country, the amount of infrastructure that must be built, resources to be used, and quality of life that we live.
From an infrastructure perspective, total wastewater load rises as population increases. The duration of high-flow stress, peak flows during wet weather, and cumulative fatigue on aging pipes all increase, reducing safety margins. As pipes approach — and sometimes exceed — their operating limits, sewer systems become more vulnerable to structural failures.

With millions of inadmissible aliens remaining in the U.S. from the border crisis alone, it is conceivable that we’ll continue to see negative net migration for the next few years. That could change if interior enforcement or self-deportations decline.
Overall environmental conditions in the United States deteriorated in 2025, as the nation continued to add more people to already overburdened ecosystems. As the U.S. population reaches 345 million, the country’s environmental problems increasingly reflect a basic mismatch between human numbers and ecological capacity.
An important reason for this affordability has been Pittsburgh’s low rate of international immigration, which has helped stabilize the area’s population and moderated pressure on the housing market. Housing affordability in American cities is strongly correlated with immigration rates and population growth. In New York, San Francisco and Boston, population increases have fueled soaring housing costs, putting homeownership out of reach for most younger residents.
Here in the United States, our population has grown by more than 90 million people since the first World Population Day, from 250 million to 342 million. This growth has been driven primarily by immigration, which reached record levels under the Biden administration and continues at historically high levels today.
“Immigration needs to move from an issue that progressives avoid to one that they seek to own,” says Claire Ainsley of Britain’s Labour Party,. “If handled well, it can be a catalyst for putting national community and citizenship at the center of a new progressive politics. There is an even bigger prize to win than beating back the populist right. It is the chance to emerge from the failures of modern globalism and forge strong, self-confident and socially cohesive nations.”

by Henry Barbaro There are countless pundits and politicians who proclaim that America’s population must grow, grow, grow. Otherwise, our economy will crash (e.g., not enough workers), and there won’t be enough people to support the elderly (e.g., pay into Social Security), join the military, pay taxes, or to keep housing values from falling.
