Coral Reef Discoloration a big problem for ocean life

Summary: In the coral reefs, the coral is getting bleached because of a change in ocean temperatures. Inside of the coral there is algae inside of the tissue called xooxanthellae. When ocean temperatures get too high, the xooxanthellae is expelled out of the coral getting rid of their bright colors.

This is how coral reefs look now

Vocabulary: A word that is new for me are xooxanthellae. Algae is noun and it means a simple nonflowering plant of a large group that includes the seaweeds and many single-celled forms. Algae contain chlorophyll but lack true stems, roots, leaves, and vascular tissue.

Opinion: I believe that coral reef discoloration is a very big problem and it can hurt our oceans population (food chain). I believe this is our fault because people cause global warming, and the reason coral reefs are getting bleached is because of ocean temperatures. This has to stop immediately because this is not only hurting the ocean it is hurting us as well.
