How does global warming hurt the ocean?

    There are several effects. Warmer water holds less oxygen, resulting in dead zones in oxygen-poor waters. Melting ice poles create a biological boom on the other hand, but mostly in species that consume oxygen, thus making the problem worse. In addition to that, higher carbon dioxide concentration in water makes it more acidic and so damaging to organisms with calcium carbonate shells as it dissolves those exoskeletons(such as coral and many plankton species). Rising ocean temperature are also one of the causes of algae blooms – sudden large growth of algae that is often depleting resources and producing toxins.
