Actually, the opposite is true: if immigration continues to mushroom, the new immigrants will have the votes to start up a land rush in our parks: first come first serve, where cost of purchase is kept to a minimum. Land we were denied all these decades could one day be consumed by people not born here. Of course, the enviro-wackos aren't concerned. I wonder why?
That horrible possibility had not occurred to me, but you may have a point. Yet another reason to stop the onslaught of immigrants, legal and otherwise.
