No environment ever 'evens out', you get population fluctuations between predators and prey. But, yes, if you leave well alone a kind of 'balance' around a certain point will occur. Trouble is we don't and have not left well alone; indeed, considering live our daily lives we can't do so. Agriculture, travel, homes, all of these things have a massive impact on the world around us.
So you can leave the rabbit population alone and what happens is you get a hell of a lot of rabbits, the foxes do well out of it, but then the rabbits make a hell of a mess of farms and gardens.
When it comes down to it, the ecology of the British Isles is not one that has ever been without humanity, and we're so well integrated into it that we can't just take our hands off it and leave it to fend for itself. Not without getting a radically different set of habitats to those we consider 'natural' or 'desirable'. |
