Here is another cost of immigration.

TUCSON, Ariz. (AP) - Illegal immigrants crossing into the United States in southern Arizona are suspected of causing eight major wildfires this year, which have cost taxpayers $5.1 million to fight. In an already busy fire season, the fires charred 68,413 acres - about 108 square miles - according to an Arizona Daily Star review of public records and interviews with land managers published Monday. Only fires bigger than 100 acres were included in the analysis, and officials said immigrants caused many smaller blazes that were quickly controlled.
