Reducing Fossil Fuel Use Only Way to Save Dying Corals

Another important reason why continuing to burn more fossil fuels is very dangerous for all of us. Excerpts from July 2008 article — Stephen

The rapid decline of coral reefs around the world offers a potent warning that entire ecosystems can collapse due to human activities, although there is hope for reefs if immediate action is taken, coral experts agreed at the conclusion of a five-day international meeting Friday.

“Reefs are in serious trouble, but don’t write them off,” Terry Hughes, a marine ecologist at Australia’s James Cook University told 3,000 scientists, conservationists and policy makers attending at the 11th International Coral Reef Symposium (ICRS) in Fort Lauderdale, Florida.

“We can save reefs if we take immediate action,” Hughes said.

More than 20 percent of the world’s reefs have died, and large areas are failing due to a combination of climate change, overfishing, pollution and sea level rise. Most of the fabulous corals that attract tourists to the Caribbean are gone and half of remaining reefs in the U.S. are in serious decline.

We may be facing ocean deserts in the future,” said Guillermo Dias-Pulido of Australia’s University of Queensland.

Great Barrier Reef Hit Hard By Australian Flooding

 

Flood caused plankton plume Great Barrier Reef

Australia’s La Niña flooding is unprecedented. At least 20 people have died, with damage and losses estimated in the many billions of dollars.

Much of the flooding is in the northeastern state of Queensland, whose rivers flow into the Coral Sea, and is expected to have a major impact on the nearby Great Barrier Reef.

Enormous amounts of sediments and pollutants are being washed off the land and are likely to have “a huge impact” on the world’s largest coral reef system, said Charlie Veron, former chief scientist at the Australian Institute of Marine Science.

The very strong La Niña is certainly causing the floods, but climate change would seem to be enhancing the effects,” Veron wrote in an email.

Lose Corals and We Will be Fighting for Our Own Survival

Interview with Marine Scientist Roberto Iglesias-Prieto

By Stephen Leahy

FORT LAUDERDALE, Florida, U.S., Jul 31 (Tierramérica)

“There would be no white sands on the beaches of Cancún without the Mesoamerican reef,” Professor Roberto Iglesias-Prieto, a marine ecophysiologist working at the Institute of Marine Sciences and Limnology of the National Autonomous University of Mexico, told Tierramérica.

Tourism is Mexico’s third leading source of revenue, and the country needs to invest much more in protecting its valuable coral systems, says the expert. But to explain the problems that coral reefs face “it is not enough to be an ecologist; one has to be an economist and political scientist as well,” he adds.

The Mesoamerican reef, which is off the Yucatán Peninsula and is shared by Mexico, Belize, Guatemala and Honduras, extends 1,100 kilometres, making it the largest in the Atlantic Ocean and the second largest in the world, after the Great Barrier Reef east of Australia.

Corals are crucial for the health of oceans and are home to 25 to 33 percent of marine life. The livelihoods of one billion people rely on coral reefs, directly or indirectly.

But the reefs are dying as a result of excessive fishing, pollution and climate change, which is heating up the water and causing acidification.

Few coral reefs will be healthy beyond 2050 if significant reductions in emissions from the burning of fossil fuels do not occur in the near term, most experts in this field agree.

Tierramérica’s Stephen Leahy spoke with Iglesias-Prieto during the 11th International Coral Reef Symposium in July in Fort Lauderdale, Florida.
