Coral reefs can take more than a decade to recover from catastrophic climatic events, with some species taking up to 13 years to recolonise their original habitats, scientists have discovered.

Marine conservationists from Plymouth University, and the Universidad Federal da Bahia in Brazil, have spent more than 17 years analysing the diversity and density of coral colonies off the coast of South America.

That coincided with the catastrophic El Niño event of 1997-98, creating an opportunity for the first detailed assessment of the long-term impact a major environmental incident of this nature can have on coral assemblages.
Professor Martin Attrill, Director of Plymouth University’s Marine Institute, said:

Coral reefs are perhaps the most diverse marine ecosystem on Earth, potentially holding 25% of the known marine species. Yet they are under intense threat from a range of local human activities and, in particular, climate change. Any impact on the corals is going to have major knock on effects on the organisms that live on coral reefs, such as the fish, and if climatic events become more frequent, as is suggested, it is likely corals will never be able to fully recover.

The 1997-98 El Niño was the most extensive global event of its kind in history, with record global high seawater temperatures in an 18-month period before and subsequently.

It prompted flooding in some parts of the world and droughts in others, but also caused severe coral bleaching and mortality in parts of Central America, the Indian Ocean, Arabian Gulf, the tropical Pacific and Brazil.

For this study, the research team used their own observations of eight species of scleractinian corals, and data from the Brazilian Meteorological Office, to create a full picture of environmental conditions and species behaviour that resulted.

It showed a significant rise in air and seawater temperatures in 1998, with increased mortality across all species and, in one case, it disappearing completely from the reefs for more than seven years.

The density of the coral in the area also fell after 1998, but then increased continuously until 2007, with recent measurements showing it is now mostly back to pre-1998 levels.

Professor Attrill added:

El Niño events give us an indication of how changing climate affects ecosystems as major changes in the weather patterns within the Pacific impact the whole world. If the reefs can recover quickly, it is probable they can adapt and survive the likely changes in water temperature ahead of us. However, we found it took 13 years for the coral reef system in Brazil to recover, suggesting they may be very vulnerable to regular climate-related impacts. This has major consequences for how we consider climate change impacts on coral reefs.

The study was conducted by Professor Attrill and Dr Francisco Kelmo, from Bahia’s Instituto de Biologia, and their findings have been published in the PLOS-ONE scientific journal.

Tandanus tandanus are a currently a no-take species in South Australia.

Primary Industries and Regions SA hosted a forum in Renmark on Thursday night (30/5/2013) to introduce the Fishers for Fish Habitat scheme.

Program leader Keith Rowling says it aims to rehabilitate native fish habitats to increase populations and improve recreational fishing opportunities.

He says it has the potential to benefit both recreational fishers and the environment.

"Basically, any time you look at opportunities to improve fishing and to improve habitat there are people who are keen to get involved," he said.

"Sometimes it's just about being able to look at ways to get resources or looking at getting like-minded people together to get things moving."

He says an increase in catfish numbers could be enough to have the catfish fishing season reinstated.

"Any time you're looking at habitat and improving fish numbers it obviously then improves opportunities when it comes to decisions regarding species that can be caught by recreational fishers, so any improvement of habitat gives a greater opportunity for improved fish numbers," he said.

Rising sea levels will lead to a drastic decline in seagrass stocks, a new study has found, but reducing water pollution may help offset the effects.

Seagrass is crucial to slowing climate change because of its remarkable capacity to absorb greenhouse gases, with some experts saying it is as important as forests in the fight against global warming.

The study, conducted by University of Queensland researchers published in the journal Global Change Biology, examined seagrass meadows along Queensland’s Moreton Bay.

The researchers calculated that seagrass there will decline by as much as 17% by 2100 if sea levels rise by 1.1 metres, unless water quality is improved or humans retreat from coastlines.

“Management to improve water quality will provide present and future benefits to seagrasses under climate change and should be a priority for managers seeking to compensate for the effects of global change on these valuable habitats,” the authors wrote in their study.

Threats

Seagrasses are important for maintaining biodiversity, habitats and offsetting carbon emissions. However, they will only flourish in a suitable substrate — the mud, sand and sediment in which seagrasses live.

The study looked at changes to water depth and clarity and the presence of roads, houses and other developments along inundated coastlines.

Seagrass meadows are under threat from urban development, declining water quality and increases in water depth due to sea level rise, which reduce the amount of light that can penetrate the water’s surface and reach the underwater foliage, they found.

“A scenario including the removal of impervious surfaces, such as roads and houses, from newly inundated regions, demonstrated that managed retreat of the shoreline could potentially reduce the overall decline in seagrass habitat to just 5%. The predicted reduction in area of seagrass habitat could be offset by an improvement in water clarity of 30%,” the researchers said in their paper.

Dr Megan Saunders, a researcher at the Global Change Institute at the University of Queensland and the study’s lead author, said the study’s findings should be used by government agencies who are responsible for managing coastal environments.

“If they want to maintain biodiversity, habitats for fisheries feeding grounds for turtle and dugong, and the key role that seagrass plays in sequestering carbon, they need to know how it’s likely to change over time,” Dr Saunders said.

“We are going to have to plan for the migration of coastal ecosystems, such as seagrass, due to sea level rise if we are to maintain the ecosystem services they provide,” she said.

Cutting our own legs off

Dr Peter Macreadie, Australian Research Council DECRA Fellow and a seagrass expert with the University of Technology, Sydney (UTS), said he was not surprised by the new findings.

“My colleagues and I at UTS predict, based on recent global estimates of seagrass decline, that if nothing is done to halt seagrass decline there will be none left in 50 years time,” he said.

“And that doesn’t take into account the effects of climate change; we just hit 400 ppm atmospheric CO2 for the first time in human history. The last time that happened was three million years ago, and it caused sea temperatures to go up by about 5 degrees Celsius and sea levels to rise as much as 40 metres.”

Dr Macreadie said that if nothing was done, the research suggests that seagrasses are in big trouble.

“These ecosystems provide immensely valuable ecosystem services to humanity, so not doing anything about their decline is equivalent to cutting our own legs off.”

Ugly ducklings

Carlos Duarte, Director of the University of Western Australia’s Oceans Institute, said the new study study offers a tool to managers to evaluate remedial actions for seagrass meadows.

“Whereas most studies have documented losses, this study takes a different approach at apportioning the stresses on seagrasses and projecting future losses in response to different scenarios, which is where the strength and innovation of the study rests,” said Dr Duarte, who was not involved in the study.

“Seagrass ecosystems are the ugly ducklings of marine conservation, yet they play key roles in sequestering CO2, protecting our coastlines and maintaining biodiversity.”

Indian Ocean nations are meeting in the Australian city of Perth this week, to discuss opportunities to develop regional ocean forecasting. 

Nearly all of the member countries of the Indian Ocean Rim Association for Regional Cooperation (IOR-ARC) will attend the week-long workshop to further cooperation and understanding on international ocean forecasting capabilities and needs in the Indian Ocean. Australia's ocean forecasting system, BLUElink which is used to predict sub-surface ocean conditions for environmental and industrial applications, will be a guide for the meeting.

Indian Ocean Coral Reef
Workshop convenor, Dr Andreas Schiller from CSIRO's Wealth from Oceans Flagship, said Australia has a long record of working with Indian Ocean Rim countries on marine, climate and oceanographic issues and this week's IOR-ARC workshop will continue that tradition.

"The workshop aims to increase the safety and efficiency of marine operations and improve marine resource management in the region by increasing awareness of the potential uses of ocean forecasting services and building new technical expertise," he explained.

Australian scientists from CSIRO and the Bureau of Meteorology scientists are currently developing the next generation global ocean forecasting models that will predict near-global ocean conditions up to seven days ahead. The models will be of benefit for defence, environmental protection and biodiversity conservation, shipping and recreational marine applications.

Dr Schiller continued: "Access to ocean observing and forecasting systems and the ability to visualise and interpret this information will assist Indian Ocean Rim nations in improving preparedness for and dealing with marine disasters, search and rescue, and emergency response activities.

"For Governments and non-Government organisations, there are considerable advantages to using environmental information from ocean forecasting systems to improve the livelihood of local fishermen and for marine industries promoting the sustainability of catch rates through environmental information.

"Ocean observations and ocean forecasting provide the basis on which many of the climate-related coastal features and extremes such as coastal storm surge and tropical cyclone predictions can be assessed and monitored."

The researchers have been working with the Royal Australian Navy to develop the forecasting capability, as part of BLUElink. BLUElink is now operational and forecasts available to the public. Australia has extended that capability and will soon have a capacity to forecast conditions for any of the world's oceans.

Dr Schiller said the need for capacity building in exploiting ocean forecasting has repeatedly been articulated at intergovernmental forums by countries in the region. A complementary capacity building programme began five years ago under the Indian Ocean Global Ocean Observing System (IOGOOS) Regional Alliance with the facilitation of the UNESCO Intergovernmental Oceanographic Commission's support office in Perth. Dr Schiller is the current Chair of IOGOOS. Just as for atmospheric weather forecasts, ocean prediction also requires a comprehensive and freely shared ocean observation network.

Although some of the related tools and models are still under development, during the implementation period of a full programme it is likely that these tools will be readily available and applicable to the Indian Ocean Rim Association for Regional Cooperation.

Dr Schiller said South African and Indian scientists have already begun ocean research programmes to build their own forecasting capabilities.

A team of international scientists is gathering in Hobart next week in a bid to use to use computer modelling to better understand the impacts of human activity on Australia's coastal environments.

Coastal models have been used to investigate and predict the water quality in coastal bays, gulfs, harbours and river estuaries such as Moreton Bay and the Derwent. "These models have been in development for the past 20 years but we know they contain approximations, and therefore uncertainties that we are working together to quantify and reduce," said workshop coordinator, Dr Emlyn Jones from CSIRO.
Albatross. fishnewseu.com
These models are seen as crucial for sustainable development of coastal and marine resources and industries because management scenarios often involve pushing systems beyond the limits for which observations are available, such as climate change impacts.

Other applications of marine biogeochemical modelling extend from understanding the effects of aquaculture on water quality in southern Tasmania, to the fate and impact of carbon dioxide in the Southern Ocean and Great Barrier Reef, and to the ability of Australia's coastal and marine wetlands and seagrass meadows to sequester and store atmospheric carbon dioxide.

Dr Jones said modellers are heavily reliant on working with observations made through coastal monitoring programs such as Australia's Integrated Marine Observing System.

"Measurement of the marine environment is at the heart of this work but we are limited to only sparse observations. Thus, we are working to predict future behaviour and give precise estimates of confidence in these predictions.

"Every day, we see the need to harness our observations and project them into a future scenario for use by environmental managers.

"Given that we cannot observe the future, models must be used to make such predictions of future system behaviour. Harnessing all available data, often from different and non-uniform sources, we can trial and test management scenarios and accommodate the uncertainties," Dr Jones said.

It also takes a lot of computation. CSIRO models are run on its supercomputer Bragg, one of the fastest 200 machines in the world. Bragg uses graphics processing units (GPUs), originally designed for computer games, to accelerate scientific computations. Even then the models can take hours or days to run. One of the aims of the workshop is to deliver results faster, not just improve the quality of the results.

Dr Jones said the workshop hoped to identify new approaches to estimate uncertainty leading to a formula useful for reviewing, forecasting and long-term prediction in marine ecosystems.

These models are crucial for sustainable development of coastal and marine resources and industries because management scenarios often involve pushing systems beyond the limits for which observations are available, such as climate change impacts.

The workshop is being funded by the CSIRO Office of the Chief Executive, CSIRO Computation and Simulation Sciences Transformational Capability Platform and the Wealth from the Oceans Flagship.

Fitzroy Partnership for River Health executive officer Nathan Johnston takes water for sampling with science integration officer Luke Ukkola

Information flow

Formed in 2012, the Fitzroy Partnership for River Health is one of Australia's largest waterway monitoring alliances in terms of both catchment size and number of organisations involved.

Report Card results will be showcased at the Emerald Show 4-5 June, Rockhampton Show 7-9 June, and Biloela Shopping Centre 13-15 June.

FROM July 2010 to June 2011, parties in the Fitzroy Partnership for River Health splashed out close to $10m in water quality monitoring programs.

This investment equated to more than 800,000 samples collected from more than 2000 locations across the Fitzroy Basin.

Today the Fitzroy Partnership for River Health will release its first report card, providing a more complete picture of river health for the basin.

Fitzroy Partnership for River Health executive officer Nathan Johnston said summary grades would be presented for 11 freshwater catchments across the basin, including the Nogoa, Isaac, Connors, Comet, Dawson and Mackenzie River systems as well as the Fitzroy River estuary.

"The report card will give the best and most complete picture on the health of our waterways in the Fitzroy Basin and as more report cards are produced they will become a valuable tool in understanding how land management practices lead to changes in waterway health," Mr Johnstone said.

Waterways of the Fitzroy Basin are the life blood of Central Queensland communities, flowing across more than 145,000sqkm of land area. "A major barrier until now has been the cost of establishing a multi-million dollar program to adequately monitor a system as immense as the Fitzroy," Mr Johnston said.

"Our 26 partners from various backgrounds including government, mining, agriculture, industry, research and community groups have overcome this barrier by working together.

WE ARE often told about the extreme greens - but what about those that are at the other extreme?

Those mining corporations that want no "green or black tape" on mining so they can mine wherever they like without any protections, or big agribusiness corporations that want no land-clearing laws and are too foolish to realise that the destruction they cause to the country will cause much greater damage to their productivity and image than any greenie will.

Indigenous activist Murrandoo Yanner wants an honest chat with the Premier over Wild Rivers legislation.

Indigenous activist Murrandoo Yanner wants an honest chat with the Premier over Wild Rivers legislation.

It is with this in mind that I have been following the Wild Rivers debate. I supported the Wild Rivers legislation; it provides some protection from the destruction that had been so commonplace under Joh Bjelke-Petersen. My fear was that a new LNP government would get in and do the same.

The Wild Rivers legislation aligns well with our ethic to look after our rivers, and protect the lifestyle that those rivers support for us. Our rivers are our supermarket. They sustain us and provide a focal point for maintaining our culture.

I haven't been around that long, but even in my short life I have watched Koories and Murries down south despair at what's been done to the natural values of their country.

People that grew up being able to catch cod in the Murray can now only catch carp. Elders watching their sacred trees dying on the banks of the Darling or Murray because some greedy rice or cotton corporation lobbied the government and because they had no means to do the same.

You couldn't really call me the moderating voice on anything, but here I find myself stuck in the middle between those that would lock it all up and those that want open-slather development at any cost. I am pro mining - it's a means to an end. A means to get our kids educated, to get them off welfare and into jobs and assist our people to move into a modern economy and not be left behind.

But not at any cost. If we are to protect our country and culture, development needs to be undertaken with the strictest possible environmental and cultural regulations - which includes staying the hell away from the rivers, the arteries of country.

We don't want to end up with our version of an Ok Tedi mine where they stuff up river systems long term for the sake of short-term dollars. Likewise, let's look at some small-scale horticulture and irrigated agriculture, but let's not start down the path to another Murray-Darling disaster.

The Wild Rivers legislation is not a barrier to development. Development can occur under its provisions - in a sustainable manner. As well as the protections, the legislation brought ranger jobs for Aboriginal people out here. Campbell Newman committed to supporting the highly successful indigenous ranger program created by the Wild Rivers legislation and he's definitely on our Christmas card list for that reason.

However, some extremists in his government want to throw the environmental progress we have made in the last 20 years out the window. The LNP is proposing removing the Wild Rivers legislation protections from the Gulf country rivers, against the wishes of Aboriginal people here.

Waterbirds of the Archer River declared Wild River Area

Waterbirds of the Archer River declared Wild River Area

I also understand removal of this legislation is proposed in Queensland's Channel Country. Again - against the wishes of Aboriginal people. Removing this protection will allow miners into river channels and floodplains, into sensitive waterholes and wetlands.

The reality for the Gulf country is that it will allow big irrigators to extract massive amounts of water from fragile rivers without limit.

Campbell Newman has said that he believes Aboriginal people have not been consulted properly over Wild Rivers. I'm willing to take him at his word, and I invite him to come fishing with me, have a look at the rivers that are the lifeblood of our country out here.

I can work with reasonable development and I can work with Campbell Newman, but he needs to convince me he is listening to us, and will protect our rivers. Sitting out here on a riverbank or the causeway with a fishing rod is a great place for an honest conversation. How about it Mr Premier?

In just the last 27 years, Australia's Great Barrier Reef has lost half of its coral. And the future doesn't look much brighter. Global warming is a threat as is Australia's booming extraction industry. UNESCO is considering placing it on its "in danger" list. DPA.

Australia's Great Barrier Reef is rapidly losing its coral, to the point that UNESCO may soon place the natural wonder on its "in danger" list. Climate change is one culprit, but so is the country's booming extraction industry. Environmentalists warn that time is running out for the reef.

The man whose job it should be to protect the Great Barrier Reef is actually afraid of water. The vast ocean, with all the creatures it contains, makes him uneasy. Only once has he visited the reef, the world's largest and most beautiful. Just thinking about the visit makes his skin crawl.

Andrew Powell, 40, the environment minister of the Australian state of Queensland, is a stocky man with a boyish face. Sitting in the neon-lit cafeteria of the parliament building in the state capital Brisbane, he smiles at the memory of his ill-fated expedition to the reef. "I get seasick very quickly," Powell explains, "and I don't do sharks very well."As he was snorkeling over the reef, he says, a reef shark swam directly beneath him. The horrifying animal was at least twice as big as he is, Powell insists. "My wife says it wasn't more than a meter long," he admits, "but it was enough for me." He swam back to the boat and refused to go back into the water.

The reef is a place of vast biodiversity and is home to a quarter of all species that exist in the world's oceans.

The reef is a place of vast biodiversity and is home to a quarter of all species that exist in the world's oceans. DPA

The 2,300-kilometer (1,430-mile) Great Barrier Reef, off the coast of Queensland in northeastern Australia, is a natural wonder. It is home to a quarter of all species that exist in the world's oceans. In 1981, it became the first ocean region to be declared a UNESCO World Heritage site.

But now UNESCO is threatening to add the Great Barrier Reef to its list of protected sites that are "in danger." The authors of a report presented to the World Heritage Committee in June are "extremely concerned" about the condition of the reef. UNESCO wants the Australian government to demonstrate that it is serious about saving the reef, or else it will be officially classified in 2014.

'Five Minutes to Midnight'

"When a place is recognized as a World Heritage site," says Fanny Douvere, the lead author of the report, "it is both a recognition and a responsibility." UNESCO, she adds, is essentially saying to Australia: "Look, it's five minutes to midnight."

She is far from the only one concerned. Australian scientists have calculated that the Great Barrier Reef, the earth's largest living organism, has lost half of its coral in the last 27 years, and coral death is only accelerating.

One reason is that Australia feels the effects of climate change earlier and more strongly than elsewhere. Not only do rising water temperatures lead to coral bleaching in the summer, but increased levels of carbon dioxide in the atmosphere also raise ocean acidity, which damages the coral.

But storms and floods also flush mud, pesticides and fertilizers from farmland into the ocean, creating conditions under which a type of starfish that eats coral can thrive. And without healthy coral, fish, crabs, mollusks, sea turtles, manatees, dolphins, skates and sharks also disappear.

Man is also threatening the reef in a very direct way. Australia has the world's largest reserves of uranium, zinc and lead. It also has rich deposits of bauxite, iron ore, copper, gold, manganese and nickel, and no other country in the world has exported as much coal in recent years.

Mining companies have dug enormous open-pit mines in the country's interior, creating moonscapes covering a total of hundreds of square kilometers. Analysts also expect that in a few years Australia will produce more natural gas than Qatar, currently the world's largest exporter. Much of Australia's coal and natural gas reserves are in Queensland.

Coal from Australia, most of which is burned in Asia, is fueling climate change, which in turn is detrimental to the reefs. International energy companies are investing many billions of dollars in new mega-mines and infrastructure projects.

To double its coal exports, Australia is deepening and expanding ports, or building new ones, even in previously untouched protected areas. The silt from excavation is dumped into the ocean, polluting the reef.

 

Plans call for several ports near the reef to be built or expanded in the coming years, with ship traffic through the reef expected to double in the next few years. The dangers posed to the reef by tankers were highlighted in 2010 when this Chinese-registered coal tanker ran aground.

'We Are in the Coal Business'

If all goes according to plan, twice as many freighters could soon be passing through the World Heritage site than do so today. And with increased traffic comes an increased risk of accidents such as the one three years ago which saw a Chinese freighter crash into the reef.

UNESCO is particularly alarmed about the plans of mine operators, which have also sparked growing resistance among scientists and environmentalists. The environment organization Greenpeace is collecting signatures to support a campaign of "civil disobedience to stop coal exports from Australia." In April, activists occupied a ship loaded with coal bound for South Korea.

"We are in the coal business," Queensland Prime Minister Campbell Newman said in response to UNESCO criticism. "If you want decent hospitals, schools and police on the beat, we all need to understand that."

The reef's designation as a UNESCO site is up for review, with the organization threatening to place the reef on its

Such a designation would be an embarrassment for Australia. Getty Images

But if current trends continue, the unthinkable could happen: the Great Barrier Reef could die.

The reef looks endless when seen from the vantage point of a helicopter. The ocean shimmers in every shade of blue, turning clear and turquoise-colored where the coral grows. Clouds cast dramatic shadows onto the water.

Of course the reef is near and dear to him, says Environment Minister Powell. "We wouldn't be Queensland without the Great Barrier Reef at our doorstep." The reef generates close to €5 billion ($6.5 billion) a year for the local tourism industry.

Powell has five children, he says. The youngest is three and the eldest 10, "and I want to leave them the Great Barrier Reef in better condition than it's in today." But the real question is what will remain of the Great Barrier Reef when Powell's children are adults.

"Our government was voted into office with the mandate to stimulate the economy," says the environment minister. "That's why we support the mining industry, construction and agriculture, as well as tourism."

And the reef?

Role Model Australia?

In keeping with UNESCO's wishes, Queensland is currently working on a strategy to develop its coastline in an environmentally sustainable way, says Powell. The national government in Canberra, he adds, is also developing plans for a marine park off the coast. The government expects to complete the overall concept to save the reef and present it to UNESCO by 2015, Powell explains.

Canberra will invest $200 million in the next five years to reduce pollution from agriculture and fight the coral-eating starfish. Queensland is contributing $35 million a year to the effort.

"I believe that we are doing everything we can to satisfy UNESCO's expectations," says Powell, leaning back in his chair. "Look, if Australia doesn't manage to have a healthy economy and simultaneously protect something as special as the Great Barrier Reef, who will?"

In this respect, Powell is right. Most tropical coral reefs are off the coasts of developing nations, whereas Australia is a prosperous country. In addition, climate change is not some abstract idea; the country has been suffering from the painful effects of global warming for some time. In other words, the Australians are in an ideal position to serve as role models.

"It would be a total embarrassment for us if the reef were placed on the list of World Heritage sites in danger," says Larissa Waters, 36. She isn't buying the environment minister's arguments. In her opinion, the government is being coopted by the extractive industry and isn't taking UNESCO's warnings seriously.

Larissa Waters

There are many in Australia who are trying to stop the degradation of the reef, including Larissa Waters. She is the first, and thus far only, member of the Green Party to be voted into the traditionally conservative Queensland Legislative Assembly. "UNESCO has concrete concerns that are simply being ignored," says Waters. "First, no ports in untouched regions; second, no port expansions that could impair the value of the reef; and third, a moratorium on port projects until 2015." Harrison Saragossi/ DER SPIEGEL

Waters is also a politician, though in a somewhat lonely position. She is the first and only member of the Green Party to be voted into the traditionally conservative Queensland Legislative Assembly. In office since 2010, she says that she hardly has any time left these days for issues other than the reef."UNESCO has concrete concerns that are simply being ignored," says Waters. "First, no ports in untouched regions; second, no port expansions that could impair the universal value of the reef; and third, a moratorium on port projects until 2015."

Her goal is to convince the state parliament to write UNESCO's recommendations into law. It's a futile struggle, and yet Waters remains optimistic. "I refuse to accept the idea that we will lose the reef," she says. "Australians have enough imagination and courage to prevent that from happening."

On a May afternoon, several hundred members of the Mining & Energy Services Council of Australia, an interest group representing the mining industry, meet at a golf club in the upscale Brisbane suburb of St. Lucia. Except for a few employees handing out name cards, the room is almost entirely filled with men.

They have come to listen to a speech by Paul Mulder, managing director for coal and infrastructure with the Australian-Indian energy giant GVK Hancock Coal. Mulder is there to present his current project: three new coal mines in Queensland's undeveloped Galilee Basin, together with a 500-kilometer rail line to the coast and a dedicated coal terminal.

While Mulder rattles off the superlatives of his project at the podium, a storm is brewing outside. Birds screech, and the wind howls through the windows, shaking the screens next to the podium. But Mulder, who is not tall but broad-shouldered, remains undaunted as he gets to the real subject of his presentation: The environmental activists who, as he claims, are damaging Australia's economy.

"I see a bunch of these activists jumping up and down, saying that we are destroying the reef," says Mulder. "They have no idea what they're talking about." According to Mulder, storms, starfish and coral bleaching are the reasons the reef is suffering. His coal has nothing to do with it, he says.

Besides, Mulder notes, coal is indispensable, providing 80 percent of electricity in Australia and China, 57 percent in India and 42 percent worldwide. "What sort of a society would we have without electricity?" Mulder asks. He says it is unfair of the anti-coal activists to deprive the "poor people in the Third World" of the kind of comfortable life they themselves enjoy.

Those who would obstruct the coal industry, according to Mulder's logic, are merely granting other resource-rich countries a competitive advantage, thereby weakening the Australian economy. As such, he explains, it is necessary for the government to eliminate bureaucratic hurdles and simplify approval procedures. The men in the room nod in agreement.

No Regulation, No Taxes

Mulder's words offer an insight into the mindset of his boss, the richest person in Australia and, depending on what happens to commodity prices, perhaps in the entire world soon -- a woman who wants people to see things her way. Gina Rinehart, 59, heir to the Hancock Prospecting mining empire, is worth about €23 billion. Rinehart doesn't speak with journalists but does pay some of their salaries. In addition to coal mining, she is also a major shareholder in Australia's leading media company, Fairfax Media Limited. And she is on the board of a television network group.

Her vision is a radical one: She wants an Australia in which the interests of the extractive industry are paramount, a place with little regulation, no taxes on natural resources or CO2, but massive numbers of low-wage guest workers from Asia, so that planned mega-projects can be implemented as quickly as possible. Rinehart uses her money and influence to make the voices of climate change deniers heard, and she has developed a following of like-minded billionaires and politicians. One of her fans is opposition leader Tony Abbott, who polls suggest could win the September election to become the next prime minister.

Abbott, the leader of the center-right Liberal Party, has characterized scientific conclusions about climate change as "absolute crap" and he successfully fought a planned special tax for the mining industry. Abbott has said that if he wins the election he will immediately abolish the CO2 tax introduced last year.

Wayne Swan, finance minister in the current Labor government, has called Rinehart and those who are like-minded a threat to democracy.

Is the Great Barrier Reef the price Australia will have to pay if Rinehart's worldview prevails?

Do Not Feed the Animals

Visitors to the natural wonder must first travel to Cairns, 1,350 kilometers north of Brisbane. The city's downtown area is filled with restaurants, souvenir shops and travel agencies. There are various ways to reach the reef: by sea, on multi-deck ships or sailboats, or by air, with small planes or helicopters that take passengers to islands or floating platforms above the reef. Once there, visitors can dive, snorkel or walk along the sea floor wearing a device that looks like an astronaut's helmet. There are warnings everywhere, admonishing visitors not to step on coral, feed animals, litter, use soap or urinate into the water.

Pale staghorn coral towers above the sea floor like a forest of bones, interspersed with sponge-like stony corals, large chunks of centuries-old coral and fat sea cucumbers resting on sandy spots. Schools of blue-and-white, yellow and striped fish swim past, and occasionally a larger fish peeps out from the forest of coral.

Russell Reichelt, 59, is paid to ensure that everything remains as it is. Head of the Great Barrier Reef Marine Park Authority, he has been tasked with investigating the impact of the natural resource boom. Reichelt is sitting in his office, with a view of the marina in Townsville, 300 kilometers south of Cairns. He looks at a map of the coast and says: "There's that old saying: death by a thousand cuts." He is referring to the deleterious effects of construction and pollution on the reef.

What Australia needs, says Reichelt, is a consensus that there is a breaking point for the reef that cannot be exceeded. "In my view, UNESCO's interest is welcome," says the reef administrator, "especially in this time of growing pressure."

The reef is also suffering from human activity in other ways. Storms and floods flush mud, pesticides and fertilizers from farmland into the ocean, creating conditions under which the crown-of-thorns starfish can thrive. The starfish spend most of their lives eating coral and have decimated parts of the Great Barrier Reef.

For the time being, his staff is focused on fighting the invasion of coral-eating crown-of-thorns starfish. The animals hide during the day, and at night they extrude their stomachs over the corals and digest them. To kill the starfish, divers inject multiple doses of sodium bisulfate into the middle of their bodies. Hundreds of thousands, possibly millions, of the coral-eaters populate the reef, making the divers' work a Sisyphean task. But at least it represents something the conservationists can do to protect the reefs.

The Great Barrier Reef remains a vital source of income for Australia, generating over six billion tourist dollars each year.

Drinking Binges and Brawls

The heart of the coal industry can be found between Townsville and Brisbane. The town of Gladstone consists of a port stretching for 30 kilometers along the coast, surrounded by power plants, coalfields, scrap heaps and flat-roofed buildings. The air is filled with the roar of machinery. Workers fly in and out of Gladstone, where the local paper reports on nightly drinking binges and brawls.

Jan Arens, 56, also works for the coal industry, as an engineer for a company that produces wastewater treatment chemicals. He can't stop thinking about the activities he has witnessed in his job. He claims that the industry dumps toxic substances into the ocean and ignores regulations. "We have laws to protect the environment, but we bend and break them wherever we can," says Arens, a big-boned man with the coarse hands of laborer. "I'm not against the industry, but I am against such dishonesty."

Two years ago, Arens founded the city's only environmental protection organization, the Gladstone Conservation Council. The group has about 50 members, he says. They distribute flyers and take out ads in the paper. But the response has been modest. "I want my children to be able to say one day that at least their old man tried to do something," says Arens.

Energy companies are currently investing $33 billion in new coal and gas projects around the port of Gladstone alone. The projects are scheduled for completion in 2015, which will coincide with the Australian's government's completion of its plan to save the reef.
