Sadly I can'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.
Most of the damage is part of climate change in general, so real action to protect the reef involves the world drastically cutting carbon emissions. Meanwhile, we can't even prevent things like this happening right next to the reef:
I was trying to subtly hint at how absolutely fucking unacceptable it is that something like the Abbot Point coal terminal was approved. How hard is it?
I don't think the average Australian cares, at least not enough for it to influence the way they act/vote.
Of course if you ask anyone on the street if they are in favor of protecting the reef they'd say yes, but when they see the price tag they would probably lose interest.
It's not so much about the price tag, but more that there are other issues nearer and dearer to their hearts. A strong majority of Australians want gay marriage laws passed, for example, but the two major parties can dodge the issue because other issues are more important to their voters.
Contrary to environmental preservation, a gay marriage law costs nothing. So if a strong majority supports it, why don't they enact it to get a free popularity boost?
I think you're wrong. I think that the Great Barrier Reef is something that average Australian really does care about. I think it's one of the few things that is capable of making people go 'oh my god, no, we have to do something'.
The thought that I've probably managed to miss my only opportunity in my life to see it is heartbreaking to me, and I'm a Kiwi, not an Australian. It's a national treasure. It's like, to me, the total destruction of the Pink And White Terraces in NZ. I will never, ever see them. Nobody will. And my future kids will never see the Great Barrier Reef.
I wonder if there is any possibility of restoring the reef after we've gotten carbon in the atmosphere back down to livable levels for it. I'm sure it's basically impossible, but if we're approaching the point of no return maybe we can invest in preserving as much of the reef as we can in aquariums to make an attempt down the road.
See my comments elsewhere in the thread for an example of people/organisations that are involved in some fairly serious activism around these issues. They do exist.
