Is the Great Barrier Reef now truly beyond saving?
Closed Tuesday, May 30, 2017, 17:39 – The Great Barrier Reef underwent major laundering of events, but it is the largest coral reef system in the world, really beyond all hope of ransom, as recently proclaimed Some titles
2016 and 2017 were very bad for the Great Barrier Reef. Due to rising ocean temperatures, the reef system, which lies along the northeastern coast of Australia, underwent two major whitening events in the last two years. As a result, the overall health of this important ecosystem has been threatened as a result, and further losses are expected in 2017.
The discoloration is the term used to describe how the warm waters of the ocean are like the corals expel the colored algae that provide them with a food source, so the white coral. This makes them vulnerable to diseases of corals, invasive algae species that do not benefit them, invasive populations of star coral and horn thorns unless ocean temperatures are beneficial enough that cold algae return opportunistic corals can starve.
The Australian government has launched since March 2015, the long-term 2050 Coral Sustainability Plan, which, at its core, a statement of how the “exceptional universal value” of the reef (as defined by the World Heritage Convention ) Was to increase every decade between the introduction of the plan and by the year 2050.
Recent scientific reef manifestations, however, were somewhat surprising.
Many caused damage to the reefs by these consecutive whitening events that the Coral 2050 plan simply is not enough to prevent the health of the reef system from continuing to decline.

This does not mean that scientists have placed the Great Barrier Reef in palliative care, waiting for the moment when it has died and gone.
First, for any sustainability plan for the reef at work, experts say the plan should take climate change into account and include measures to combat it. Currently, the Coral 2050 plan does not.
A panel of experts who assessed the level of Coral 2050 in early May, said:
“Members agreed that, in our lives and in our clocks, large areas of the Great Barrier Reef and surrounding ecosystems are significant long-term damage that may be irreversible if action is not taken now. Science informs us we are unprecedented in the history of mankind.Although this is in itself can be a cause of action, the extraordinary speed of the changes we observe makes the one action even more urgent. ”
“The Committee believes that measures to reduce greenhouse gas emissions should be essential to the response.This should be accompanied by increased efforts to improve the resilience of coral and other ecosystems that make up the Great Barrier Reef “On managing reefs to maintain the benefits offered by the reef.
At the recent Coral Summit, Townsville, Australia, these scientists have echoed this call to action.
“The last two years underscore the need to take urgent action to curb the decline of corals,” said Dr. Russell Reichelt, president of the Great Barrier Reef Marine Park Authority. “The Great Barrier Reef is a large, rugged system that has previously been shown to be capable of rebounding, but the current changes are undermining the reef’s resilience.”
“The Summit expressed deep concern about the need for global action to reduce greenhouse gas emissions, the engine of climate change.”
Second, however, while the Coral 2050 plan can not achieve its main objective, according to The Guardian, experts call for a much more achievable goal – maintaining the ecological function of the reef system.
