Increasing Carbon Dioxide And Decreasing Oxygen Make It Harder For Deep-sea Animals To Breath

ScienceDaily (Apr. 18, 2009) — New calculations made by marine chemists from the Monterey Bay Aquarium Research Institute (MBARI) suggest that low-oxygen "dead zones" in the ocean could expand significantly over the next century. As more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. Read more here...

About all that can survive in these dead zones are vast hordes of slimy, amorphous, useless jellyfish (r.). They can inflict painful stings on swimmers who fail to heed warning signs (l.)
