True Wild Boar have been extinct in the UK since the 13th century.
Over the years people have tried to reintroduce them (16th and 17th century) and every time they have tried they have been hunted in to extinction again. 1. They are highly destructive to agricultural crops which are already under high enough demand.
2. With the last wolf being shot in the 17th century they now have no natural predators.
3. Much of their main habitat has now been destroyed which is likely to push them into more frequent conflicts with man.
Agricultural crop production, ie. food production, in the UK is a marginal industry of ever diminishing importance, as evidenced by the ongoing decline in political will to secure such production. By contrast wild boar hunting is a growth industry generating real, new and unsubsidised financial returns and employment and is therefore an important fillip, throwing it's presently small lifeline to the fragile rural economy, much may it grow and prosper.
You are correct, there are no wolves yet (thank goodness) but there is the motor car, a voracious killer. Control measures to reduce the number of speed related fatalities and injuries on rural byeways might be a spin off benefit of more wild boar based traffic calming measures randomly appearing around the country. This can only be hoped for as a means to aid in curing man's self destructive use of the said motor car.
However, in conflicts between man and wild boar (such as you perhaps intend in your mentionings) my natural sympathies tend to lie with the underdog. In any case in Mano-a-Scrofa related face-offs the pig usually runs away faster than any man can chase.
As to the lack of habitat, isn't that always cited as being one of the ultimate sins of modern farmers. Any increase in wildboar must surely serve to alleviate such allegations against a marginal and ethnically minor group. Yes/No?
So, all in all and on the basis of the answers you supplied, I'm afraid I cannot presently form the view that your initial statement, which I questioned, has any validity.
