yes coral reefs are very endangered and so are many of of the species that live in them
coral reefs start by the decomposition of organisms living under water.
The way coral reefs are being endangered are by us. We keep on throwing waste on the beaches. The water washes up on shore. And the waste floats down to the coral reefs. And the fishes and species that live there are either eating it or living in it. If they eat it the chemicals in the waste can kill them! if they are living in them then the saltwater in the coral reefs since the water is so warm, it release the chemicals in the water and the water gets into the species gills and kills them. It is up to us to stop throwing or leaving waste on the beaches so the coral reefs aren't in dangered anymore. So that is how the caorl reefs are endangered.
