If current trends continue, the Colorado River system will lose its remaining resilience to withstand further dry periods. The combination of declining flows and rising demand threatens the region’s rivers, wetlands, fish, and wildlife.
Wildlife conflicts are not as much the result of animals encroaching on humans, but of people expanding into wildlife space. Human population growth narrows migration corridors, reduces buffer zones, and displaces habitat. As a result, encounters that once would have occurred deep in forests or remote valleys now happen in neighborhoods and school zones.
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.
A pronounced slowdown in net immigration (legal and illegal) has slowed population growth, eased housing demand, and made rents more affordable in several markets.
Road salt causes long-term water contamination. Mass immigration expands roads and salt use. Population growth makes the damage unavoidable.
The border is secure and illegal migration is down. So, do we still need to be concerned about immigration? The answer is an emphatic yes.
For decades after the Clean Air Act (1970), new emission standards, cleaner fuels and technological innovations brought steady air quality improvements to America’s metro regions. But those gains have since stalled, as population growth, with its traffic expansion and rising energy demands, overwhelms the benefits of air pollution controls.
Politicians across the political spectrum agree that America has a housing crisis. Home prices and rents have surged beyond what many households can reasonably afford.
While business journalists and housing experts tend to focus on supply, the demand side of the equation is equally important in determining housing prices. When the number of families grows faster than the number of housing units, competition for existing housing increases and prices rise. This has happened in many parts of the country over the past four years, due to immigration-driven population growth.
Each Thanksgiving, we say we’re “going home for the holidays.” But more and more, it feels like we’re running the gauntlet through an endless traffic jam. The culprit? Rampant population growth.
