I Love foxes, but what he said is true. Foxes in a lot of countries are considered pest animals. For examples in UK from the cancellation of fox hunting their number has been increased to an dangerous level. Forced by hunger, caused by a decrease of their preys, they have attacked children.
That's a myth. Decades before the fox hunting ban, we already had a massive urban fox population. There have been very few cases of fox attacks on humans, and they've all been urban foxes.
The fox hunts that are now banned were all in rural areas, and had no effect on urban foxes. They were ceremonial, and did not make any significant dent in fox numbers. What was being protected was a traditional sport of the upper class, and it was banned because of the cruelty: the foxes were run to exhaustion and then ripped apart. Of course, rural foxes are a problem for farmers, and they have always and still continue to shoot them to protect their livestock. They use no more than two dogs to drive out the foxes into open running so that they can be shot.
