Got Environmentalists?

Illegal aliens are getting creative in their border crossings. They aren't simply walking across the border anymore. Now, when they cross over parts of the border covered by national forest, they actually start forest fires to distract park rangers and border patrol, and even burn the rangers out of observation posts.

Where are the environmentalists when you need them! If environmentalists can complain about a border fence damaging some ecosystem in San Diego, then what about deliberately torching a US national forest? (To say nothing about smoking US Border Patrol out of their guard towers.)
