What caused the great auks to become extinct?

Well, some rich man came along and he thought, " Wouldn't it be cool to kill the last two Auk penguins and stuff them?! " So he paid someone to shoot them and stuff them. Sadly, his plans followed through and the penguins were killed. The last two. A female, and a male. If he wouldn't of shot them, they could have reproduced and on and on. See what hunters can do? Hunters are evil.
