"The roundup proponents say that the snakes are overpopulated, and that they're overrunning town, so they had to do something about the snakes," Amarello said. "But they're in no danger of being overpopulated. There's no science to suggest that there are too many rattlesnakes, or that we need roundups to control them."
The real purpose of the rattlesnake roundups appears to be financial gain, according to Amarello, as each event brings in a large flow of tourists. The event in Sweetwater, Texas, which is the largest rattlesnake roundup in the country, attracts about 30,000 people.
