[SMH] Great reef catastrophe ; Half of great barrier reef now gone

post #1 of 71
Thread Starter 
Quote:
Half the Great Barrier Reef's coral has disappeared in the past 27 years and less than a quarter could be left within a decade unless action is taken, a landmark study has found.

A long-term investigation of the reef by scientists at Townsville's Australian Institute of Marine Science found coral had been wiped out by intense tropical cyclones, a native species of starfish and coral bleaching.

Good to know that they can actually come back to life and grow again.

Just like all the species that have gone extinct in the last 100 years? Some things will not just "be fine" without a bit of proactive conservation.

Half of the reef has disappeared in the last 35 years, and at this rate in another 15 years another half of what is currently there will be gone. Global warming only intensifies the cyclones that help destroy it, and the acidification of the water from air pollution also contributes. Unless a huge effort to restore the reef occurs I'm not sure how it will survive.

It seems the problems aren't as much the weather, but the starfish that thrive on the coral;
Quote:
"If we could stop crown of thorn outbreaks tomorrow then we could get the coral cover on the reef back to 1985 condition in less than 20 years," said Dr Doherty.

Although the weather is still breaking it up. But that's pretty much why the great reef is there, to serve as a barrier from storms.

Acidification is something most people don't even consider. At my college I went to a seminar of a marine biologist and she showed pictures or a reef she studies over the past 20 or 30 years.
She stood at the exact same spot and took pictures underwater. The decay and loss of life there over time is heartbreaking when you see how awesome it used to look.
