-Additionally, even though some fish in the population were maturing at an earlier age, none was actually growing faster.
No cod has a way of speeding up its rate of growth, so the younger reproductive age actually meant that smaller fish were reproducing.
-And when you're a small cod reproducing, you produce fewer eggs than a large cod.
The smaller cods simply don't have the body mass to reproduce as many eggs.
The over-fishing pressure on the cod population was pushing the cod into an evolutionary corner.
They were having a harder and harder time surviving.
Student: But what can be done to prevent other scenarios like this?
I mean obviously we need a better way to manage environmental resources.
Professor: Well, what do you guys suggest? Carol?
Student: Hmm, uh, maybe privatize the resources?
A private owner would want to manage the resource efficiently in a sustainable way.
Professor: Ok, but the problem is privatization doesn't necessarily result in better management of an environmental resource.
