Honestly, by analyzing fossil records of CO2 in past times, like the Jurassic period, I believe that somewhere in the ocean there are creatures with genomes adapted or rapidly adaptable to an increased acidic ocean.
The geological average of CO2 in the atmosphere seems to be about 20 times the current amount.
Not necessarily corals are the optimum staple life form of the oceans.
I do not claim to know anything about what would the optimum staple life form in the ocean, I'm simply open to the possibility that an increase in CO2 could lead to a improvement in photosynthesis ability for algae and therefore an increase in ocean life.
