First thing they do after breaking into America is trash it. Michelle Malkin links to a report that highlights the problem:

Cleanup crews from various agencies, volunteer groups and the Tohono O’odham Nation hauled about 250,000 pounds of trash from thousands of acres of federal, state and private land across southern Arizona from 2002 to 2005, says the U.S. Bureau of Land Management.

But that’s only a fraction of the nearly 25 million pounds of trash thought to be out there.

Authorities estimate the 3.2 million-plus immigrants caught by the Border Patrol dropped that much garbage in the southern Arizona desert from July 1999 through June 2005. The figure assumes that each illegal immigrant discards eight pounds of trash, the weight of some abandoned backpacks found in the desert…

…In 2002, the United States estimated that removing all litter from lands just in southeast Arizona – east of the Tohono Reservation – would cost about $4.5 million over five years. This count didn’t include such trash hotbeds as Ironwood Forest National Monument, the Altar Valley, Organ Pipe and Cabeza Prieta.

Since then, Congress appropriated about $3.4 million for a wide range of environmental remediating measures in all of southern Arizona. This includes repairing roads, building fences and removing abandoned cars.

The five-year tab is $62.9 million for all forms of environmental remediating for immigration-related damage across southeast Arizona, including $23 million for the first year.

Here’s a thought. Whenever the US catches an illegal, they are sentenced to six months of community service on the border, before being sent back. They might be less inclined to return if they know they are going to spend six months picking up garbage each time they are caught.
