If that was what I cared about I'd have chosen a very different career path, believe you me.
The reason I shoot deer is that I care - passionately - about being able to produce and supply meat from animals that I have killed and butchered myself. It's been my interest since I was a child, and I believe very strongly that it's the best way of doing things, for a whole host of reasons including animal welfare. But it can never be anything other than small-scale, and it will never make much money. The only thing that really matters to me is that I'm doing something that I enjoy doing.
If I was legally allowed to kill, butcher and sell my own sheep I would probably never have started shooting deer, and I would be just as happy and equally penniless.
