Have we ever as a species successfully changed our behavior on a scale needed to address something like climate change and underwater oxygen loss? What would be the closest “we’ve got to change or perish” moment we’ve successfully navigated?

Historically speaking over over a billion years almost every species has consumed one thing and output another to the point of extinction while another species that consumes that grows and repeats the cycle. Climate change has been the story of evolution since life appeared on earth and aglae filled the atmosphere with gasses.

I mean yes but where does that get us? The great oxygenation event wasn't exactly good for the organisms that were alive at the time.

True, but most people don't think about why that is the case. They'll blame slavery (abolished over 160 years ago), or the "exploitation" by capitalists (that produce wealth for all). Some may claim that the US has more natural resources, but The US is rich because of the freedoms and rights that our citizens have. Look at the poverty of the Soviet Union or Mao's China, or in Cuba today. I cannot for the life of me u…

Let's consider the economies of Communist nations. I suggest we take into account a bit of regional history. North Korea is a basket case. But after three generations of tyrants it is arguably a monarchy. China is a success story, end of. By any measure, China has come a long way since the Communist regime took over in 1949. You could say something similar about Soviet Russia. By the 1980s it had stagnated, but the a…

Note that I referred to Mao Zedong's China and not the China of today, which has embraced a "controlled capitalism" after their flirtation with communism failed miserably (as it always does).

Can you trust the USSR lifespan statistics? I wouldn't.

You cite other countries, none of which are under a purely communist government, because that has never worked out for anyone other than the dictators that ruled them.

Do people have to know about what generates their electricity? They get input now, but we could probably just stop taking public input on new infrastructure and that would avoid poorly motivated protests of wind farms or nuclear.

They do not need to know what generates there electricity but... - when what generates the power changes the landscape they can see, many people get upset, however irrationally - many people are emotionally attached to lifestyle objects that use fossil fuels, i.e. cars, boats, planes, etc - even where there are good options, most people are not willing to spend one extra penny - even when there are options that cost…

Perhaps more importantly than any of those, often people react out of fear of what they think other people will think.

Maybe everyone bitches about gas prices, but we would all get over it pretty fast if politicians just pulled the band-aid off. Instead they use it as an opportunity to pull down any crab that tries to save us from the bucket.

I don't think statistics are the issue, or what the exact definition of a communist is. For what it's worth, self-described communists are still in charge in all of the countries I mentioned, with the obvious exception of Soviet Russia.

Let's step back for a moment. I think you should acknowledge that you have constructed a world in your head where communists do battle with capitalists, and capitalists are the good guys.

That idea is outdated and increasingly ridiculous. Clearly it is a narrative that serves the interests of billionaires in West Palm Beach. I don't know that working people buy it. It wasn't communists who put them on a zero hours contract.

We did a reasonable job with ozone depletion, but that has much lower costs. https://en.wikipedia.org/wiki/Ozone_depletion

Indeed. But still amazed we did anything about it, since it didn’t immediately affect population centers or cause economic impacts.

I just can’t see the same happening in today’s political climate…

Ozone, leaded motor vehicle fuels, asbestos, acid rain, DDT, commercial whaling, atmospheric nuclear testing.

(Not all of these were existential to humans necessarily, but all have been largely successes.)

Oxigen is ALSO, and perhaps in vast quantities produced at the bottom of the ocean, by lumps of metal that react with sea water (aka Dark Oxygen). Interestingly, there are now massive marine harvesting operations targeting that very ore. https://www.smithsonianmag.com/smart-news/scientists-discove...

Deep-sea mining has been studied and foreseen for at least 50 years, but it's never been economical. It is possible that current technology will allow for mining of nodules, but this still seems unlikely to me. https://en.wikipedia.org/wiki/Deep_sea_mining#History

but this still seems unlikely to me.

It is already underway and going live soon:

Below, our current progress report:

COMPLETED: Sponsorship Agreement COMPLETED: Exploration Contract COMPLETED: SK1300 NORI Technical Resource Statement; SK-1300 NORI-D Project Initial Assessment (PEA)(Excel tables) SUBMITTED: Collector Test Environmental and Social Impact Assessment APPROVED: Pilot Nodule Collector System Test COMPLETED: Pilot Nodule Collector System Test COMPLETED: Collector Test and Monitoring June 27, 2025: Exploitation contract application submission expected
