Here's my opinion:
The corals are getting bleached, fast. Fish that rely on those corals to survive die. Fish that rely on the fish that rely on the coral die. What I'm trying to say is the lower something is on the food chain, the more important it is. If the lowest thing on the food chain dies, everything dies. If the highest thing on the food chain dies, nothing happens. If all reefs die this would have a terrible affect on the ocean. Were above the ocean on the food chain, so if the ocean dies, we die. We need to leave da fish alone!
