From the New York Times:
More than two million strong statewide, hogs are increasingly encroaching on residential communities — destroying any lawn or fence in their path and, with sharp tusks, occasionally injuring an unlucky person in their way. Even urban lawmakers are now taking the threat seriously.
If, or when, the governor signs the bill into law, hog hunting from helicopters — a practice currently allowed only for some landowners — would be legal for any licensed hunter willing to buy a seat in the air. Texas lawmakers say the legislation could curb the $400 million in agricultural damage feral hogs cause annually and deter their spread into urban areas.
… the animals uproot crops, pastures for cattle feed, fences and the native habitats of ground-nesting birds and reptiles. And the hogs will eat almost anything: corn seedlings, peanut plants, peach trees, bird eggs and baby calves. They can also spread disease to domestic pigs and humans, and they foul watering holes.
