Why does Guam have so many snakes?

I have been reading some of the articles from the conservative website I stumbled across yesterday. The article is about Guam’s snake infestation. In the article the author suggests that the Guam natives should be paid to eradicate the snake issues. Is it not rude and degrading to suggest that people from a poorer country be paid to hunt snakes? I was so appalled and disgusted. This is why the U.S. has such horrible immigration policies; because they think people from poorer countries are cave men. Here is the link to the article. Is it just me or am I overreacting?
