Exploring Hydrocarbon Depletion
Already preempted you RockDoc. (see my previous post) Once again you twist the truth with the best of them
The first 'corals' appeared in the mid-Triassic. During the Triassic-Jurassic extinction event, a time of high ocean acidity and atmospheric CO2, reef development collapsed for millions of years, and resumed again with new coral families in the Jurassic once CO2 came back down.
The skeletons of corals are made of calcium carbonate which dissolves in conditions of high acidity.
The precursors of the corals we have today evolved in the mid-Miocene and have NEVER BEFORE seen high ocean acidity or CO2 levels higher than current levels

Corals dead at Great Barrier Reef
Thats maybe even worse then the Arctic Ocean Sea Ice melting.
The Great Barrier Reef receives the run-off from 35 basins which drain 424,000km2 of coastal Queensland. River discharges are the single biggest source of nutrients to the inshore areas of the Great Barrier Reef World Heritage Area.
Over the past 150 years sediment inflow into the Great Barrier Reef has increased four to five times, and five to ten fold for some catchments.

Coral reef ecosystems world-wide have been subject to unprecedented degradation over the past few decades. Disturbances affecting coral reefs include anthropogenic and natural events. Recent accelerated coral reef decline seems to be related mostly to anthropogenic impacts overexploitation, overfishing, increased sedimentation and nutrient overloading. Natural disturbances which cause damage to coral reefs include violent storms, flooding, high and low temperature extremes, El Nino Southern Oscillation (ENSO) events, subaerial exposures, predatory outbreaks and epizootics.

the problem, among many, is fish stocks are collapsing. We are eating it all.
Harvesting is efficient to the point of extinction.
