On the colonization of our ecosystem, usually if you have food for no more than 10 animals, the 11th and 12th die. It's a rude competition of Mother Nature. If we have six million seals right now it's because we have food for six million, but maybe there isn't food for seven million. Usually the ecosystem has its own manner of managing the population. That's a general concept of biology, and we aren't very good at that.
