Great Barrier Reef at 'terminal stage'

I grew up on the coast of the Great Barrier Reef in North Queensland and I can say that the current state of the reef is almost unrecognisable to what it was 20-odd years ago.<p>While a large part of this damage has been caused by rising sea temperatures, another large component is due to the run-off from agriculture, refineries and mining. The latter being a directly contributed by the local population.<p>The region is currently in a economic recession and many of the mines and refineries have either slowed or ceased operation. Anecdotally, the sentiment of the population affected by (un)employment by these industries are either unaware or ignorant towards the damage that the industries are having on this sensitive ecosystem. Instead they are consumed by how they are going to make ends meet.<p>In this environment, it is unthinkable to allow Adani expand their Carmichael mine to further exacerbate the situation. Add to this, that a former Adani board member is appointed to evaluate the environmental impacts of the expansion. Adani is the biggest direct threat to Australia, both environmentally and economically and they are in talks with the government to be provided with a $1 billion tax-payer funded railway line. Adani and the Carmichael mine expansion are rifled with corruption.<p>The issue of the reef and climate-change in general is a fairly untouched issue in Australian politics. I&#x27;m not sure that we are going to get anywhere without foreign intervention.<p>If you are interested, I do urge you to read some material on Adani and the Carmichael coal mine expansion and perhaps donate to a &quot;StopAdani&quot; cause.<p>Wish us luck.

Many posts here about how sad and disgusted people are. Not much about people taking personal responsibility.<p>What do people think the carrying capacity of the planet means? Sustaining more humans means sacrificing other life that competes for our resources. It means pollution rising until it doesn&#x27;t quite kill us but is well above the levels of a pristine, clean environment.<p>Nobody wants to live near the carrying capacity because approaching it means sacrificing anything that doesn&#x27;t keep us alive.<p>Every round trip flight across the country you take contributes almost one year&#x27;s allotment from the Paris agreement for one person -- <a href="https:&#x2F;&#x2F;co2.myclimate.org&#x2F;en&#x2F;portfolios?calculation_id=719701" rel="nofollow">https:&#x2F;&#x2F;co2.myclimate.org&#x2F;en&#x2F;portfolios?calculation_id=71970...</a>. Flying first class and you&#x27;re well over it. Eating meat contributes a lot too. Having more kids in western cultures contributes significantly.<p>Who among us, reading this, hasn&#x27;t gone over their annual limit in just a few hours of flying, not to mention their regular life otherwise? How many have blown past their Paris limits already this year?<p>Some would say the damage was done by past generations. Okay, well what beautiful part of nature will our behavior destroy years from now? People keep posting to HN that since we can&#x27;t change that a lot will happen, it doesn&#x27;t matter any more, we should just enjoy ourselves, but there are different degrees of destruction.<p>Alternatively, we can fly less, drive less, eat much less meat, and have fewer kids. We don&#x27;t need to wait for legislation. In fact, it&#x27;s the fastest way to get legislation, since politicians follow voters.<p>In my experience, acting on all those things improved my life tremendously (including not flying for a year+ <a href="http:&#x2F;&#x2F;www.inc.com&#x2F;joshua-spodek&#x2F;365-days-without-flying.html" rel="nofollow">http:&#x2F;&#x2F;www.inc.com&#x2F;joshua-spodek&#x2F;365-days-without-flying.htm...</a>), more than almost anything else. I&#x27;m more fit, enjoy my neighborhood and neighbors, and spend less money and there&#x27;s nothing special about me.

Although I&#x27;ve never seen the Great Barrier Reef, I was recently in Belize and snorkeled around its Barrier Reef. It was painfully obvious that the reefs were extensively bleached(though still quite beautiful). It&#x27;s quite shocking to think that 30 years ago the reefs looked completely different from now and in another 30 years may not even be around. I hope that in the future we won&#x27;t be reduced to having to point to pictures in a book if people want to witness the beauty of nature but this seems increasingly inevitable. What a shame.

There are some excellent scientists and programs attempting to improve water quality (particularly catchments that flow into the reef) and the crown of thorns starfish.<p>Unfortunately these are badly underfunded, not coordinated at a national level as they should be, and do not address the biggest threat - climate change. The reef is doomed unless something is done about CO2 emissions. It&#x27;s probably already too late.<p>The loss of the GBR will see a collapse of tourism industries, and entire ecosystems will die off. There are going to be huge impacts in the next 15-20 years to come out of this.<p>A lot of low lying countries in the pacific will get the triple whammy of increased cyclone activity, rising sea levels and a loss of reefs and the fish populations that they subsist on. There are huge humanitarian disasters ahead.

I saw a bleaching event in Thailand last year, it really is depressing to see. This year, the same sites have seemingly recovered and I&#x27;m really happy about that. But seeing the pictures of completely bleached white corals in the article and knowing that&#x27;s probably the future for a lot of these reefs breaks my heart. Coral reefs are magical places and we&#x27;re destroying them for future generations, maybe even the current one.

Sadly I can&#x27;t remember the last time we had any real action to protect the reef, and our current government is all too willing to put businesses above the environment.

My cousin Sam[0] runs the environmental side of things at GetUp and is putting a lot of time and effort into raising awareness about the reef. They&#x27;re currently fundraising[1] for a targeted campaign in 12 Liberal electorates with the aim of encouraging MPs to break their silence and listen to their constituents on the issues surrounding Adani and the GBR.<p>Full disclosure: GetUp is a politically partisan organisation with strong left leanings. But I think the work they&#x27;re doing around these issues is rooted more in common sense than politics.<p>Is anyone else involved in any grassroots-level efforts to save the reef? I&#x27;d be interested to hear about them.<p>[0] <a href="https:&#x2F;&#x2F;twitter.com&#x2F;samregester" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;samregester</a><p>[1] <a href="https:&#x2F;&#x2F;www.getup.org.au&#x2F;campaigns&#x2F;great-barrier-reef--3&#x2F;the-white-death-of-the-reef&#x2F;turnbull-schmoozes-while-the-reef-is-dying" rel="nofollow">https:&#x2F;&#x2F;www.getup.org.au&#x2F;campaigns&#x2F;great-barrier-reef--3&#x2F;the...</a>

This is what keeps me up at night. If we don&#x27;t find an efficient way to extract CO2 and methane from the atmosphere, I fear that mankind might go extinct.

The sad fact is that even these devastating developments do not make us change systemically to the extent required to counterfeit them.

This really saddens me.<p>I spent a week or so on Lady Elliot Island more than a decade ago, snorkelling every day. Because it is a protected area, the fauna are unafraid of people. I would dive down into these cavernous bowls of coral and be surrounded by schools of fish, rays, turtles. It was amazing.<p>I live in Europe now, but I always hoped to take my children there to see it one day. Seems there won&#x27;t be much to see.

The real culprit for coral bleaching? A swift fall in mean sea level during a major El Nino event. See: <a href="http:&#x2F;&#x2F;www.biogeosciences.net&#x2F;14&#x2F;817&#x2F;2017&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.biogeosciences.net&#x2F;14&#x2F;817&#x2F;2017&#x2F;</a>

&gt; Coral bleaches when the water it’s in is too warm for too long. The coral polyps gets stressed and spit out the algae that live in inside them. Without the colourful algae, the coral flesh becomes transparent, revealing the stark white skeleton beneath.

This is merely the inevitable outcome of what we&#x27;ve known has been coming for a while, even if many haven&#x27;t wanted to acknowledge that the corals were effectively already dead. <a href="http:&#x2F;&#x2F;www.nytimes.com&#x2F;2012&#x2F;07&#x2F;14&#x2F;opinion&#x2F;a-world-without-coral-reefs.html" rel="nofollow">http:&#x2F;&#x2F;www.nytimes.com&#x2F;2012&#x2F;07&#x2F;14&#x2F;opinion&#x2F;a-world-without-co...</a>

Is improving water quality the decided-upon method for preventing (or even reversing) bleaching of coral reefs?<p>It seems like that ship has sailed, and now more technological advances are required.<p>Speaking from zero expertise or experience in marine biology, is it not possible to manufacture massive quantities of synthetic coral that somehow corrects for the changing water quality to enable coral life to flourish?

So ... when do we shoot some rockets high up and spray something reflecting sunlight, changing earths albedo? Plan B?

Pauline Hanson &amp; Malcolm Roberts will pose in front of the coral display at the Townsville Aquarium and tell us it&#x27;s all a beat-up.

I&#x27;ve been hearing the reef is at death&#x27;s door for 30 years. When I go, it looks amazing. Still. Maybe this scare campaign is different to all the other ones. Maybe this time as they cry wolf there really is a wolf. Maybe... If so it&#x27;s a perfect example of the environmental movement destroying their own credibility so that not many in Australia, among those who love the reef, care what they&#x27;re saying this week. People need to call bullshit on bullshit whether that bullshit is in the service of great justice or not. It&#x27;s still bullshit and it still trashes credibility. Outrage fatigue is far worse when you know you&#x27;ve been had.
