Doesn't the extraction of fish have a positive impact on the O2 balance?
I thought that overfishing the kinds of big fish we like to eat will just lead to a growing population of smaller fish and other marine life.

What I'm also saying is that I think that other fish (or lifeforms in general) will take their place.
I agree that the oceans change - a lot - due to human influence. Some species will dwindle in numbers and disappear. It takes a long time for new species to emerge. But what I'm not so sure is that the overall change necessarily would have to be so negative in the long run.
