Today Homeland Security Secretary Michael Chertoff said:
"Illegal migrants really degrade the environment. I've seen pictures of human waste, garbage, discarded bottles and other human artifact in pristine areas,"
"And believe me, that is the worst thing you can do to the environment."

Friends who have been around the border area have told me of some pretty awful and filthy camps out in the desert. I'm sure some of the trash hurts local wildlife while it sits out there but it's quite small and pretty well hidden from view unless you are off-road. If you're an animal, it's probably more interesting than disgusting.
This fence for now has reached 151 miles. It will eventually reach more than 600 miles long. It will probably have gaps every "several miles"for migrating animals It is supposed to allow some small animals under it but not larger ones such as tortoises, gray wolves, bighorn sheep, ocelots or the like. The fence is 16 ft tall and built to withstand a 10k lb motor vehicle hitting it at 40 mph. So the supports for the fence run fairly deep into the ground.
The fence costs $3 million per one mile. That's a lot of trash hauling. A lot of the trash pickup can and is being done by volunteers.
Even when you take away the fact that it's an eyesore that is much larger than a lot of garbage piles, it will pretty much stop most animals and probably not that many people.
In response to environmental concerns, Chertoff says he'll use a congress approved environmental waver to bypass any attempts to stop the fence.
