Keith Delacy, a former Queensland Treasurer, writes in The Australian about the Great Barrier Reef.
…well-managed reefs around the world can sustain an average seafood harvest rate of 15,000kg per square kilometre per annum. The average harvest rate for the Great Barrier Reef is 9kg. That’s right, 9kg, or if you like a minuscule 90g per hectare.
[…]Claims of widespread over-fishing at our levels of harvest are the height of absurdity. There is absolutely no scientific evidence of threatened marine species, population collapses or effects on marine biodiversity from fishing. Almost without exception, away from the coastal and tourist influences, the Great Barrier Reef is pristine, rarely visited and home to the same number of fish species today as at first human settlement.
[…]And all this debate about the danger posed to the reef by shipping is nonsense. One cyclone causes more reef destruction than if all of the ships that ever traversed the reef since the beginning of time crashed into it.
During World War II thousands of ships were sunk on or around reefs, bombed and smashed, some of them oil tankers. And where is the evidence of that today? To the extent that they went down on a reef they are now part of that reef. The Chinese bulk coal carrier Shen Neng 1 ran aground on the reef east of Rockhampton in 2010 amid cries of outrage and demands to cease bulk shipping through the reef. But in reality it was a minor blip on the vastness of the reef, one that will quickly rectify itself.
The UN can go and shove it.
