They're invaders. Big. Often carrying pathogens. Devouring everything in sight. And ranging over more and more of the U.S.
Pigs, swine, hogs, boars. Wild, feral, invasive, non-native. Whatever words you use, these 6 million tusked omnivores are on the loose, stomping farther in the United States than ever before, from Oahu to Texas (shown above) and Mississippi.
What damage are they doing? How can they be stopped?
