Since when was snaring illegal? And you can get a permit to shoot ravens. But the only realistic threat to wildlife in the UK is loss of habitat. And it’s the shooting industry that’s the main contributor, not the RSPB/PCA or the public.
The moors would be all grass, hedges ploughed up, no game crops, woodland cleared for mono-culture cropping. You think the food keepers get out of bed all winter to chuck on the ground is somehow exclusive?
Not defending it, just stating the facts. The countryside would be practically barren without it.
