From Smithsonian:

Wild hogs are among the most destructive invasive species in the United States today. Two million to six million of the animals are wreaking havoc in at least 39 states and four Canadian provinces; half are in Texas, where they do some $400 million in damages annually. They tear up recreational areas, occasionally even terrorizing tourists in state and national parks, and squeeze out other wildlife.

Texas allows hunters to kill wild hogs year-round without limits or capture them alive to take to slaughterhouses to be processed and sold to restaurants as exotic meat. Thousands more are shot from helicopters. The goal is not eradication, which few believe possible, but control.
