Sick "sports"

I am not against killing animals if it has to be done...I think I would be a vegetarian if i felt that way and I have shot rabbits. However I feel it has to be done in as humane way as possible. The rabbits had to be controlled, there was no other way, but I got absolutely no pleasure whatsoever out of it. I have also shot at pigeons, but they just laughed at my incompetence and the grey squirrel fired back using a pine cone and unlike me scored a direct hit between my eyes.
If I can I will work with wildlife, well i like having it around. Unfortunately as someone has said we have wiped out a lot of our big wildlife so the natural balances of predator prey are no longer there, so now people have to cull deer ( note cull, not hunt like those silly rich people do in Scotland) and very expensive and inefficient it is as well.
