CORALS---THE GREAT SURVIVORS

For at least fifty years, agitated academics have been predicting the end of the Great Barrier Reef. Now international “experts” are also sprouting coral calamity. But despite the alarms, the reef is still there.

An early scare focussed on the Crown of Thorns Starfish which was going through one of its sporadic population booms. Such plagues come and go with the natural cycles of growth and decay. But the reef survived.

Then experts got scared in case someone drilled for oil on the Reef – so we had a Royal Commission and banned all that. However marine life seems to flourish around all artificial reefs such as jetties, shipwrecks and drilling platforms. Rigs have to be regularly cleaned of marine growth.

Natural hydrocarbons have been part of the wild environment for longer than corals, which may explain why corals are remarkably tolerant of hydrocarbons. Despite natural oil and gas seeps, man-made spills, and hundreds of offshore drilling rigs, corals still thrive. 

After the worst oil spill ever during the First Gulf War there was no clean-up attempt apart from oil skimming because the 700 oil-well fires had priority. Fresh crude oil floats and is a danger to sea birds, but it soon reacts with air and salt water to become solid tar balls which sink to the sea floor. An inspection of the sea bed later to catalogue “the disaster” found teeming wildlife, with sea-grass, snails and fish thriving after the fertilising effect of the oxidising oil.

Corals are even thriving at the exact spot in the Montebello Islands where two atomic devices were tested by the British in 1952.

Another scare concerned coastal development and agricultural run-off. Again destruction of the Great Barrier Reef was forecast. Academics were summoned and a huge national park was established for their playground. Run-off still occurs, rivers still flood, but the reef is still there.

Lately global warming scares such as coral bleaching and ocean acidity have mesmerised the media. These are supposedly caused by wicked humans burning hydrocarbons and using energy by doing things. So we introduced a carbon tax, despite the fact that no unusual warming or acidity can be measured. And the reef is still there.

Now we are told that port dredging near Bowen is going to destroy the Reef. The Great Barrier Reef is 2,400 km long – stirring some mud at one small spot 40 km from the reef is unlikely to be noticed by the coral. Moreover, the stuff being dredged is comprised of natural material eroded from the land and put there over millennia by coastal rivers. Compared with the silt load discharged by rivers like the mighty Burdekin in a normal wet season, or stirred up by cyclonic surges, dredging is a non-event. The Reef has been coping with sediments like that for thousands of years.

All plants and animals need minerals for optimum health. Marine life gets its minerals from erosion of rocks on the land. Coastal rivers (and dredging of river silt) stir up the minerals which supply the off-shore environment. Like all nutrients, some is necessary, too much brings harm. 

Corals are among the greatest survivors on Earth and have been here for about 500 million years. Many of the types of corals found on reefs today were present in similar forms on reefs 50 million years ago.

Since corals first appeared there have been five mass extinctions when over 50% of all life forms on land and in the seas died. These episodes usually included massive volcanic events that filled air and sea with debris, lava, heat and acid fumes. And still corals survived.

Then there were asteroid impacts that created huge craters that dwarf man’s puny ports. Debris, rock, mud and slush were flung in all directions – far more and further than man’s dredging will ever do. Corals even survived this.

Corals also survived several deadly ice ages when sea levels fell so low that many coral reefs left their skeletons stranded as limestone hills on dry land. But always some colonisers followed the retreating seas and survived.

Then came the hot climate eras when the great ice sheets melted and sea levels rose dramatically. Some coral reefs drowned, but others just built on top of the old drowned corals forming the beautiful coral atolls we see today. Corals flourish in gently rising seas such as we have today – it gives them room to refresh and grow vertically.

And if the water gets too warm, coral larvae just drift into cooler waters closer to the poles. The Great Barrier Reef would move slowly south.

Corals have outlasted the dinosaurs, the mammoths and the sabre-toothed tiger. Captain Cook’s ship was almost disembowelled by the sturdy corals of the Great Barrier Reef in 1770. If Cook came back today, he would be unable to detect any changes in the Reef.

We should of course minimise soil erosion, human pollution of offshore waters and direct damage or interference with the Reef. However, green extremists would like to sacrifice all of Queensland’s coastal industry on the coral altar - exploration, mining, farming, land development, tourism, forestry, fishing, and shipping. They need reminding it is only rich societies who can afford to care for their environment.

No matter what the future holds, corals are more likely than humans to survive the next major extinction.

In the event of yet another Ice Age we must hope that reef alarmists have not denied us the things we will need to survive - food, energy, chemicals, shelter, concrete and steel generated by carbon fuels.

Thats a picture of sand dredging in Dubai making their artificial Islands. Nothing to do with the reef and just more greenie lies. I know it's Christmas but god I hate Greens!!

I live in Cairns, almost every week in the local paper, there is a breathless story of how the Great Barrier Reef is dying. I think if there were less Greenies and "Scientist : tramping all over it there would be a longer life expectancy. Ben Cropp ( a local diver and film maker) has said that in the 50 years he has been diving, there has been little change in the health of the reef, but nobody takes any notice of a local. There is much more credibility given to a so called scientist. who probably hasn't actually been to the Reef

Remember all the thousands of oil and petrol tankers that went down in World War 2? They were sunk over the oceans of the World. Did anyone mention 'pollution" during or after the War? Of course not! The oceans recovered and life went on. We zapped Hiroshima and Nagasaki in August 1945 with two atom bombs. How many millions of people live in those cities today? Frigging Millions! Climate Fraud should be a Capital Crime!

Newsflash Girls. It costs over $100K for a government paid funeral in the Territory to send off an aboriginal deceased. If an Elder passes, you can at least treble that. You pay for it ..... its nice for you to know.

ignorance is strength for the greens. http://www.menzieshouse.com.au/2013/12/ecotard-conference-in-london-confirms-being-green-is-really-the-new-red.html?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+MenziesHouse+%28Menzies+House%29

That is the way of life. Here today and gone the next.

chaser,......right! You realise that you'd be gone before the reef?

China already has two military / scientific bases on Australian soil in Antarctica, with another two proposed. Where is Greenpeace ,W.W.F. and associated lefty garbage ? The Chinese will not as kind as the Russians when dealing with these misfits.....

Viv, Do you know which group used this photo and where?

I notice there has been no public comment from Flannery or the I PCC on the first snow fall in Cairo Egypt in 112 years or the fact that Israel had a metre of snow.

Not much different to Labor using a photo of the steam rising from a power station suggesting it is carbon pollution.

Good news with the Rigby murder verdict. Here's hoping the judge pots the buggers right and proper now!

Not the Greens and their associated nincompoops.

Good Luck with that, Boofhead Wilson!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Does anyone care if business succeeds in this country.....
OYOTA will challenge a court ruling that barred it from asking its workers to sacrifice wages and entitlements in an effort to slash costs at its Melbourne plant.

The Federal Court last week ordered the company to abandon putting a vote on a new workplace agreement to the 2500 workers at its Altona plant.

But Toyota lodged an appeal against the decision on Thursday.

Justice Mordy Bromberg found that Toyota breached the Fair Work Act by putting "further claims" in an enterprise agreement with the unions.

In his judgment, Justice Bromberg said Toyota proposed in November to vary the agreement by reducing employee entitlements, including wages.

But a group of four Toyota workers argued the proposal had breached the agreement and contravened section 50 of the Fair Work Act, and won the court's approval.

Toyota Australia president and chief executive Max Yasuda last week said the decision was a blow to the company's efforts to remain competitive in Australia.

Careful, we seem to be letting the truth get in the way of Labor/Green ideology here, and according to the latest opinion poll, 52% of the electorate want their precious Labor/Green alliance back. Yep, after six years of debt, boats and bullshit, they want them back. How quickly the masses forget.

When you see Greens organizing and participating in picking up rubbish, raising money to clear the oceans of plastics, and in some little way walking the walk, I might take a bit of notice. Currently all you hear is them spouting their wretched depressing opinions with their bums sticking out, fingers wagging and telling the rest of us what to do and indoctrinating our children.

And what is Tim Flannery? A mammalogist. But that didn't stop a corrupt socialist government from salivating over his lies and bring in a carbon tax. What morons warmists are. Climate change is nothing but a man made religion. You worship the earth and the environment. Seems Flannery doesn't believe what he preaches though - his home is waterfront and the only access is via boat. What 'useful idiots' you are. Look up what that means. I bet you live in or near a city. Melbourne?

You can understand why the Greens and the Australian Mafia Party wanted a tax on CO2 emissions, They couldn't wait to get their greedy little fingers into the tens of billions of dollars it would generate annually. Typical social parasites, something for nothing at the expense of the consumer. Dare I say these people are throwbacks from the Neanderthal which we, the ambition, ethical, enthusiastic, Ingenious, conservatives left behind. I dread the day when Labour get back into power, Australia is finished.

Sounds like he has more qualifications and integrity than Tim Foolery !!
