Human activity may represent the greatest threat to coral reefs. In particular, global warming, coral mining, pollution, over-fishing, blast fishing, and the digging of canals are serious threats to these ecosystems. Agricultural runoff may also threaten reefs by encouraging the growth of harmful algea.
In a given body of water -
Coral Reef produces algea growth -> algea is eaten by midge larvae -> which is eaten by damselfly nymphs -> which is fed on by steelhead trout -> which feeds humans.
When coral reefs die, so does the food chain.
