Christopher Wassif Mass Coral Bleaching Event

Given that I led the class discussion on ecological degradation, I thought that I would share an article that I I just came across, which states that 93% of the Great Barrier Reef is currently being affected by its worst coral bleaching event. Coral bleaching occurs when zooxanthellae, (a symbiotic algae), is expelled from coral. This causes them to turn white. A number of different stressors, such as warmer or colder water than usual can allow this to happen. While bleached coral is technically not dead, it is in a compromised state, and more susceptible to death. Therefore, unless the environmental conditions that caused the bleaching to occur in the first place are reversed, it is likely that at least some coral will die. Given that the Great Barrier Reef is the largest reef system i n the world, 93% of it being in a reduced state of immunity so to speak, is devastating to put it mildly. Given the importance of coral as a biodiversity hotspot, it is imperative that we try to protect them, and other coral reef structures as best as we can.

    I really like your post Christopher as not many of us know whats happening to the Great Barrier Reef. Today one of Twitters moments in world news states how climate change is ruining the Great Barrier Reef more than previously thought. In people responding to them, one person posted this article below and it made me very sad and mad. To know that people could care more about business and profit then the environment itself is heartbreaking. Capitalism is killing the environment.

    You’re right we should try to protect the coral reefs and their structures not only because they affect it in ways that are harmful and lead to death but because of the sea life that depends on the coral reefs as a source of shelter. The sea life that live and depend on the coal reefs are also important to the surrounding environment. If something happens to the reefs, it can lead to a chain of harm not only to the sea life but to other parts of the ocean and to humans, since we rely on the compounds of the coral. the importance of the coral to humans is that we can create medicines that treat cancer, if this is what we have discovered so far, image what we could discover if the reefs flourish, it will not only benefit the sea live and environment but people too.


  3. Wow i never knew about this. Not many people worry about things like this or even know about this. People don’t realize that ‘sea creatures” need to be protected to. I agree with Katherine’s statement that if something happens to the reef it can not only harm the sea life but humans as well. Mostly everything on earth is useful and need to be well taken care of. Yes we need to worry about human life and what is going on but one thing can lead to another which will effect everyone. So we need to be more away and look more into things like this and see how we can help.
