"it is still far from hopeless"

Sorry - it is hopeless. Earth is (as David Suzuki makes clear) akin to a test tube of a culture medium and we humans are the rapidly multiplying bacteria producing excrement.

And the driver behind it all? - the shareholders' dividend. Only when the last shareholder is poisoned off, will the destruction stop.

I can't help but feel depressed in reading this very well articulated article by Dr Veron ringing the alarm bells.

What's more depressing? The 'deniers' and 'naysayers' with their collective heads stuck in the mud and their collective minds entrenched in the past.

What else is dependent on the Great Barrier Reef? Think about it.

“Over the past decades there have been many stories in the media about the plight of the Great Barrier Reef.”

And the current scare campaign is just another of the “many stories” being put about. A marine scientist, this author admits that he was wrong in the past; he can just as easily be wrong this time, too.

However, right or wrong, he and the rest of us mere humans can do nothing about it – just continue to listen to guff and have politicians dig deeper into our pockets to pay for solutions that don’t exist.

The arrogance of some people who think that they can ‘remedy’ nature is mind-boggling.

The world has COOLED for the last 8 years. Even the IPCC has admitted this. They have even now rewritten their forecasts to say, cooling for 10 years.

The oceans have COOLED for the last 3 years, when serious measurement has been taken.

The AGWs must be getting worried that they are about to get kicked off the gravey train to have this sort of rubbish being pushed.

The IPCC has no idea , & this bloke has even less. Lets just hope the sinking gravey train does not pollute the reef, now we know that the nonexistrnt AGW won't.

"The arrogance of some people who think that they can ‘remedy’ nature is mind-boggling."

We cannot of course remedy the natural cycles in nature but of course we can remedy nature insofar as our impact apon it. If we have the capability of destroying we are also capable of saving it.

Just one very simple example: Sharks eat small fish, fish eat phytoplankton, phytoplankton absorbs CO2. If we kill too many sharks there are more small fish and less phytoplankton to absorb CO2. Human remedy is to adopt a sustainable fishing policy.

When will the anti-green lobby understand that the earth's resources are not finite and that we can have great influence, good and bad, over the environment we live in. Humans do not live in a vacuum separate from other living organisms.

Yes the jury is still out on AGW but we can't ignore the fact that we might are partly responsible even if we can't agree on the percentages.

Mr Right has said so, therefore it obviously must be right.
