Coral expert J.E.N. Veron, former chief scientist of the Australian Ins ute of Marine Science, had this to say in an excellent interview he did with Yale Environment 360 last year: "the science is clear: Unless we change the way we live, the Earth's coral reefs will be utterly destroyed within our children's lifetimes.
"You may well feel that dire predictions about anything almost always turn out to be exaggerations. You may think there may be something in it to worry about, but it won't be as bad as doomsayers like me are predicting. This view is understandable given that only a few decades ago I, myself, would have thought it ridiculous to imagine that reefs might have a limited lifespan on Earth as a consequence of human actions. It would have seemed preposterous that, for example, the Great Barrier Reef--the biggest structure ever made by life on Earth--could be mortally threatened by any present or foreseeable environmental change. Yet here I am today, humbled to have spent the most productive scientific years of my life around the rich wonders of the underwater world, and utterly convinced that they will not be there for our children's children to enjoy unless we drastically change our priorities and the way we live."
Reefs are the ocean's canaries and we must hear their call. This call is not just for themselves, for the other great ecosystems of the ocean stand behind reefs like a row of dominoes. If coral reefs fail, the rest will follow in rapid succession, and the Sixth Mass Extinction will be upon us--and will be of our making.
I might add that not only are reefs the ocean's canaries, they are incredibly valuable in their own right. According to the World Meteorological Organization, coral reefs provide economic services--jobs, food and tourism--estimated to be worth $30 billion per year. NOAA put this figure at twelve times higher, $375 billion each year. Corals cover just 0.2% of the world's oceans, but contain about 25% of all marine species.
