I'm not from Australia but some give this friendly shortcut to their country. I believe it's about the World of Oz book reference, way to say it's big area but strangly isolated in the same time (my understanding)...but we are seing it's not isolated and we are all both responsible at our own individual scale and all interdependent
If I have not understand correctly Oz shortcut, australians correct me please. Maybe it's less in use today ?

Don't forget that all-important towel, as well.
Ancient Rome had some useful advice too (first image).
The second image summarizes our current situation. It's taken from a 2017 state-of-the-planet research summary put together and signed by some fifteen thousand scientists from one hundred and eighty four countries ( https://www.cbc.ca/news/technology/15000-scientists-warning-to-humanity-1.4395767 ).
The only good news in that image is at the top left corner. Everything else is a disaster, for example, 60% of all vertebrate life on planet earth has disappeared during the 55 years from 1960 to 2016.
And here's a very similar, even more recent (Nov 2019) research paper: eleven thousand scientists issued a warning that we are facing a climate emergency: World Scientists’ Warning of a Climate Emergency | BioScience | Oxford Academic

Now I have a mental image of a roomful of sad kangaroos, with patches of singed fur, sitting around in a bar, dimly lit by flickering red and blue neon lights, staring forlornly into their beer-mugs, and talking about the good old days before their country was on fire.

No, it is not.
Beer generates a lot of CO2 during fermentation. Same goes for wine (I should know that being a winemaker).
There is a brewery in Melbourne that now grows algae to eat all the CO2 that they generate.
Yeah right!
With all the deforestation for farming the Kangaroos are in their element and are more plentiful than ever. We should eat them rather than cattle.And where did that carbon in the CO2 come from in the first place?
Well, it was pulled out of the environment by the plants when the hops, barley, etc were grown, and used to make the organic compounds out of which the plant(s) made the barley, hops, etc. This happened recently, most likely within the last year or less (nobody uses million-year-old barley.)
When the beer ferments, it's returning that same carbon back to the environment.
Therefore, there is negligible increase in global CO2 levels as a result of this sort of process. It's a bit like taking a teaspoon of sugar out of one side of the sugar jar, and putting it back in on the other side of the same jar.
When you burn a two hundred year old tree, the situation is somewhat worse; carbon that was pulled out of the atmosphere two hundred years ago to build the tree's tissues is being put back into the air now, in the present. And, of course, the now-dead tree stops sucking still more carbon out of the atmosphere, as living trees do.
On the other hand, petroleum takes some 50 million years to form in the earth's crust, so "new" petroleum is at least that old; most oil deposits are between 60 million and 250 million years old, with some upto 500 million years old. Petroleum comes from mostly plant and marine fossils, creatures which took carbon out of the air 50 million to 500 million years ago to build their bodies.
And that's why burning fossil fuels (petroleum and its numerous products) is so bad; we're spewing CO2 that was sucked out of the atmosphere hundreds of millions of years ago back into the atmosphere, and we're doing this at an incredibly fast rate.
We humans only began using petroleum in quantity around 1850 or so, and in less than two hundred years, we've burned up an enormous amount of petroleum that took tens of millions of years to form. We're putting that carbon back into the air at a rate hundreds of thousands of times faster than it was originally pulled out of the air by the plants and tiny marine animals that eventually fossilized and turned into petroleum.
Enjoy your beer guilt-free (unless you're an alcoholic and it's ruining your life, obviously.) Beer is not the thing that's destroying our livable atmosphere.
What is destroying our atmosphere is the hundred million barrels of petroleum the world is burning every single day. (The number was estimated at 99.2 million barrels per day in 2018, and projected to be 100.6 million barrels per day in 2019. )

It is by comparison.
The BBC chart to which I referred takes into account the production processes.

Yes gnobuddy, you are right, beer production is not responsible for the situation we are in right now. At least not as much as the fossil fuel industries.
Your simplistic explanation is just that, simplistic.
But read this before making some loaded comments:
Carbon produced by winemaking ‘five times more concentrated than planes’
Just a small snipet:
“We should be capturing carbon in wineries so they become carbon neutral. Carbon from the winemaking process is five times more concentrated than planes and cars. A litre of juice produces 60 litres of carbon dioxide. Why aren’t we trapping it?”

I don't see it simplistic, rather realistic.
The discussion of beer seems inconsequential, it would be like arguing that you should not make female tampons or disposable diapers for babies because they are made of cellulose (wood pulp, because it is a highly absorbent material) among others.
My mother washed cloth diapers and they were reused, there were no tampons.
Make a mental effort and you will see the relationship with the exposed by gnobuddy
And where do we get with that?
