Probably fair to say that rewilding isn't going to happen any time soon in the UK, at least not to the extent that Monbiot is suggesting. However, despite strongly disagreeing with a lot of what he says, on this, I agree with him entirely.
No doubt he takes an extreme view of the subject, but it might start the ball rolling in the right direction. In fact, I know of instances where the interests of a few farmers have been ruthlessly pushed aside, for the sake of the ground, environment, flora and fauna, and (Filthy word), Tourists.
Now, between September and March the welfare addled farmer must remove his animals from the common land. Having been born and bred right in the middle of this area, and knowing most the people involved, i can tell you that they are outraged at this imposition on their given right to graze their sheep on common land, with no concern or responsibility whatsoever for any environmental damage.
Guess what? The common land is starting to recover............
I can only speak for the area I live in, but 30 years ago, most people here were involved with agriculture in some way, they all got a bite of the welfare and accepted the pushing out of hedges, felling of hardwood, polluting of streams, conifer plantations, and so on, without question. Indeed, they prided themselves upon how good it was, and how good the welfare was. (The taxpayer footed the bill for this environmental catastrophe, through subsidies)
Now, there are a huge number of people living around here, who are nothing to do with agriculture whatsoever. They neither know nor care that a carrot grows in the ground, and isn't made in a factory in China.
They have made their money, moved to the country, and are seriously starting to wonder what it is that is so good about farmers, that so few of them can have such a negative impact on so many peoples lives, and be paid, from the government, to do it.
Why should rural areas be the exclusive preserve of the farmer, what about everybody else that lives here? Why is the government having to support farmers with so much money to farm sheep, when the land is so unsuitable, why don't they pay the farmers to grow Pineapples, it would be equally as (in)sensible. Both are totally unviable, without subsidies.
Why not make some effort towards rewilding the countryside, so others can enjoy it?
To be fair, small inroads are being made. The Farmers' main aim was to produce food, now it as The Guardian of the Countryside, and the best welfare is available to the farmer through environmentally sound initiatives. It hasn't gone anywhere near far enough, yet, and some of the new rules and regulations are an environmental disaster, but that is only to be expected. No one is going to change the world overnight. But it is changing, and more of the incomers, and second generation incomers, are starting to realise that they are seriously under represented in this area.
(I rarely work for farmers, I work mostly for incomers. It's eye opening.......)
