In Britain a central rationale in support of fox hunting has been challenged by a scientific study. Hunting advocates have long claimed that fox hunts keep the fox population from exploding, protecting livestock. But scientists from the University of Bristol said today that banning fox hunting would not cause an increase in the fox population. This announcement adds some concrete support to a debate that has been waging for years between hunting defenders and animal welfare campaigners. The scientists got the opportunity to test assumptions about the effects a ban would have because of foot-and-mouth disease outbreaks in Britain in 2001 that led to a ten-month ban on fox hunting. The British government is currently in a six-month period of consultation in search of a compromise on fox hunting between the House of Commons, who earlier this year voted for a full ban, and the House of Lords, who voted for licensed hunting.
