Perhaps, but the United States does not have an overpopulation problem. We have lots of problems, but too many people isn’t one of them.
Someone’s taking discredited 1970s wacko environmentalism and using the immigration issue to try and revive it.
I disagree. Our ancestors moved here and struck out for the prairie, forest, and plain. They hacked a living out of the hard virgin earth and created something great in the process. Today's immigrants head for the cities, where they stay, soaking up social services and cramming into tight quarters.
They lower the quality of life for city-dwellers.
