The main cause of coral reef death is bleaching. Corals are colonial symbiotic organisms – the coral’s polyps provide a home for zooxanthellae (photosynthetic algae), which in turn provide the coral with oxygen, and the products of photosynthesis (glucose, glycerol, and amino acids) and help with waste removal. What causes coral reefs to die? That slows their growth and makes them vulnerable to algae, disease, and death.
Increased ocean acidification caused by the absorption of carbon dioxide causes bleaching , too. The same conditions can be seen in the Caribbean and other sites around the world. The bleaching of these reefs occurs when rising water temperatures cause corals to expel algae living in their tissue. This turns the corals completely white. When the algae-like single cell protozoa are expelled from the corals, they stop growing and die off.
The symbiotic relationship between the two are crucial to coral survival. Great barrier reef dead. Huge sections of the great barrier reef stretching across hundreds of miles of its most pristine northern sector were recently found to be dead killed last year by overheated seawater.
Scientists have officially declared the great barrier reef to be dead. Once the coral is dea the reefs will also die and erode , destroying important marine life spawning and feeding grounds. Animals that rely on coral for protection and cover, such as grouper, snapper, oysters and clams, would also be negatively impacted. Part is the mystique, because most of the tourists who come are not scuba divers.
Bleaching Is not immediately fatal for the corals. After expelling the algae, the corals can survive for some time. Without coral reefs, there could be a rippling ecosystem collapse in the oceans, with devastating effects on the planet. If the temperatures remain high , the corals can die.
For coral reefs around the worl time is running out. With so many different species living on the reef , it’s easy to assume that the extinction of just one or two won’t matter to the reef ’s overall health. The death of the reef is caused by coral bleaching, something that happens when the water is too warm. The effect is akin to a forest after a devastating fire.
Months of monitoring will now be needed to assess the ongoing damage. The world’s largest coral reef is in serious danger. Coral bleaching happens due to increased water temperatures. As coral continue to be assailed from all sides, the question becomes: what happens to a coral reef when the coral disappear?
To get an idea, says University of Queensland ecologist Peter Mumby, look to Jamaica. In their place grew seaweed forests. And some experts even believe that unless drastic action is taken, coral reefs. The impact if this happens would be catastrophic. Whilst most people see the reef as simply a tourist attraction, the effect it would have on marine life and even coastal towns in Queensland would be huge.
But fixing that problem will require remaking the energy. Although it generates more than billion dollars annually for the Australian economy, it has many negative effects on the reef. Tourism operators, educators, multimedia professionals, marine biologists, scuba divers, engineers – people who work out there and could really see that we could make a big difference really quickly if we band together.
