The adaptations you're talking about happen over centuries.
The changes you're talking about are happening over decades.
These changes will not be limited to just the oceans.
And the main takeaway point from that George Carlin clip that I can find is that the planet will be fine because people won't be. I can only assume you didn't bother to watch it before posting it for others to watch.

- jacquesm 9y agoFungi are not a very good example of such adaptability when you are mainly talking about vertebrates.

- dpwm 9y agoThe adaptations you are talking about were in fungi, in the presence of radiation which didn't kill them. This is in comparison to fish, in which adaptations take a longer time, where the decrease in oxygen is a direct threat to life.
- throwaway9990 9y agoIt has to be a threat to life. Otherwise, no fungi that had potential for such energy consumption would have been selected for. Same with fish or birds. With fish, the ones that can live in a slightly lower O2 environment will be selected for and survive better than the ones who can't. Those that can't would die off because they won't be able to compete as well. This adaptation can happen within a decade.
