Today's Washington Post article reports that wild pigs are a major and increasing problem in Pakistan. A quick search on the Internet will reveal that the problem with pigs and habitat destruction is worldwide.
What can be done to control the problem? South Carolina's Department of Natural Resources' news release describes the issue and regulations, including recent legislation passed to control the transportation of wild pigs throughout the state.
DNR encourages those who have wild hogs on properties they own or hunt to lethally and legally remove every hog they have the opportunity to remove...Feral pigs have been called by some an "ecological train wreck" and the destructive nature of this invasive species lends itself easily to such a description. All feral pigs share an unbridled appetite and can destroy hundreds of acres of farmland as well as native plants and wildlife habitat in just a few short nights. Free roaming pigs reproduce at a prodigious rate and are capable of producing two litters of up to a dozen piglets a year.
As noted in the Washington Post article, ignoring the problem does not make it go away and in fact as the exact opposite effect!
