So, the justifications for anyone to go in and kill wild boar in the sorts of numbers actually needed to address the problem simply don't exist.

Guardian - George Monbiot - I was wrong about veganism. Let them eat meat - but farm it properly

There's no doubt that the livestock system has gone horribly wrong. Fairlie describes the feedlot beef industry (in which animals are kept in pens) in the US as "one of the biggest ecological cock-ups in modern history". It pumps grain and forage from irrigated pastures into the farm animal species least able to process them efficiently, to produce beef fatty enough for hamburger production. Cattle are excellent converters of grass but terrible converters of concentrated feed. The feed would have been much better used to make pork.

Pigs, in the meantime, have been forbidden in many parts of the rich world from doing what they do best: converting waste into meat. Until the early 1990s, only 33% of compound pig feed in the UK consisted of grains fit for human consumption: the rest was made up of crop residues and food waste. Since then the proportion of sound grain in pig feed has doubled. There are several reasons: the rules set by supermarkets; the domination of the feed industry by large corporations, which can't handle waste from many different sources; but most important the panicked over-reaction to the BSE and foot-and-mouth crises.
