Overfishing of sharks is harming the coral reefs.

So recording to the article shark numbers are reduced because of commercial fishing and the decrease in the herbivorous fishes which play a key role in promoting reef health. "It's strange in our analysis that when the shark numbers are reduced, we see a fundamental change in the structure on reefs." Mark Meekan said. He also found out that numbers of mid-predator start increasing and the reducing of herbivores such as parrotfishes. The parrotfishes are very important to coral reef health because they eat the algae that would otherwise overwhelm young corals on reefs recovering from natural disturbances. According to all that, this means coral reefs are facing a number of pressures both from direct human activity, such as over-fishing, as well as from climate change. Tracking studies show that, in many cases, individual reef sharks are closely attached to certain coral reefs. This means that even relatively small marine-protected areas could be effective in protecting the top-level predators and allowing coral reefs to more fully recover from coral bleaching or large cyclones which are increasing in frequency due to the warming of the oceans as a result of climate change.
This article is pretty interesting to me because this show you how just because of one thing got unbalanced it effectively the whole food chain. "Shark fishing appears to have quite dramatic effects on coral reef ecosystems" said Jonathan Ruppert. As you can see, this considering a problem because human keep overfishing and because of the climate change which is human involving.
That's why people have to look more into the ocean and see how changed then figure it out how to fixed it, it's better more than less. Relatively small marine-protected areas could be effective in protecting the top-level predators and allowing coral reefs to more fully recover from coral bleaching or large cyclones which are increasing in frequency due to the warming of the oceans as a result of climate change. So what in my mind is do anything you can to protect the ocean just like protecting yourself.
