Erin Lee, throughout this entire thread you've been distorting my replies. I feel that it is a personal attack and this is the last time I'm going to respond to you.

I'm saying that the idea to cull came from humans observing nature. Culling is the act of removing the unfit individuals from the group. Most of the time, these animals are killed, yes. If humans [and nature] didn't do this, we wouldn't have breeds or species which are adapted to living in certain conditions.
The commercial breed of turkeys, for example, are rarely culled unless they have a life-threatening condition or otherwise aren't going to make money. They are not selectively bred to survive tough conditions, to be resistant to disease or even live to be more than a year old. These turkeys don't even know how to mate and past their first birthday will die because they are bred to put on a gross amount of weight and eventually their skeleton can no longer support it.
