Some of the devastating environmental impacts of illegal immigration through these protected areas include:
The Park Service has closed the ohono O'odham Indian Reservation, Organ Pipe National Monument, and Buenos Aires Wildlife Refuge due to the "unacceptable level of risk to the public and staff" from the "high level of illegal activity going on."
Illegal Roads and Abandoned Vehicles
Declining Wildlife Populations
According to the Fish and Wildlife Service, mass illegal immigration is a likely contributing factor in the dramatic 79 percent decline in the U.S. Sonoran pronghorn population between 2000 and 2002.
These are just a few examples of the massive environmental destruction being caused by rampant illegal immigration in southern Arizona. Similar damage is being done to remote, fragile lands in California, New Mexico, and Texas.
