I have never stated that farming does not have an impact. I merely have an issue with people saying that all farming only ever has a negative impact with respect to bio-diversity when its incorrect. Farming has both a negative and positive impact to the countryside.
Precisely. We, as a species, need to realise that allowing farmland to return to its former self is just not feasible, however emotionally pleasing that would be.
We have decimated biodiversity even worse than farming in the name of house building, infrastructure building (roads etc) and all other manner of man-made alterations to the natural UK habitats... Yet it is farming that is, once again, getting the waggly finger and told it is in the wrong.
