Future Effects of Ocean Acidification (IMAGE) University of Plymouth Caption At a site with a CO2 concentration of 900ppm, corresponding to conditions predicted for 2100, the high CO2 favors the growth of low profile algae that covers all the available substrate, and inhibits the growth of corals and other habitat forming species. This leads to a drastic decrease in biodiversity.
