I was alarmed when I saw the title of the thread, because "extinction" is when an entire species is killed or dies off. Like dodo birds, the great auk, wooly mammoths, saber-tooth tigers, the T-rex...I didn't see how a free trip could cause an entire species to be wiped out. I'm relieved you were just talking about butchering a batch of chickens, and nothing's been made extinct!
