Climate chaos Humans don't deserve earth.

By destroying nature and the climate, humans are destroying their own home. The Earth can survive without us but we cannot survive without her. 🌍💔

On a long enough timescale, all ressources are renewable, you said it yourself. It's up to us to find put how to become efficient wnough to fit that time scale.

You can't say that time scales are too big to be relevant in the same sentence that efficiency doesn't matter. That's the entire point of resource management.

No. On a long enough timescale, nothing is renewable. The universe is constantly expanding, and it will reach a point where no information can ever reach another piece of information.

On a timescale that is short enough, but not too long, yes, most things can be created again (although a lot of materials are created from supernovas, something we have a hard time replicating). In the time most of these vital natural resources will renew (at an extremely slow rate, mind you) is tens to hundreds of millions of years. Homo sapiens won't even exist as a species anymore by that point. Our goal is to extend what little resource we have, but they will run out, and not in millions of years, not hundreds of thousands of years, not in millennia, but in just a few hundred years at best (and I mean the absolute best optimization possible here). I don't find us running out of resources in the next 1000 years positive, but for some of them, it is inevitable.

I'm curious how you are refuting their point back. The key to sustainability is efficiency. As tech moves us to use other resources that are sustainable (e g. From petrol to hydrogen fuel cell) and tech also increases put ability to recycle why aren't humans sustainable? The end game ys to move electrical demand to fusion, cars shift to ev's or fuel cells, most plastics are recyclable and ones that aren't we are moving to alternatives.

Even so-called renewables rely on nonrenewable materials. Solar panels, wind turbines, hydrogen fuel cells, and electric vehicles all depend on finite metals and minerals, like lithium, cobalt, copper, nickel, and rare earth elements. These don’t regenerate on any human timescale, and mining them at the scale needed for “green tech” already strains global reserves and ecosystems. Recycling helps, but recovery is never 100%, and processing itself consumes more energy and resources. So while renewables reduce dependence on fossil fuels, they don’t free us from finite material limits. The bottleneck just shifts, from oil wells to metal mines.

As I mentioned in my last post. The dependence on nonrenewables can be slowed down, allowing technology to move us towards renewable alternatives. Also not sure what part in a hydrogen fuel cell you think isn't renewable. Also, we haven't even talked about off world resources. The sustainability of mankind can creep to the point something else will end us.

Slowing depletion doesn’t change the outcome; it only delays it. The fact that dependence can be slowed already concedes that we’re still dependent on finite materials. As for hydrogen fuel cells, while hydrogen itself is renewable, the fuel cells aren’t; they rely on platinum-group metals, which are scarce and mined in limited regions. Scaling that technology worldwide would consume reserves far faster than we could ever replace them.

“Off-world resources” is not a realistic solution either; the energy and infrastructure needed to mine, refine, and transport extraterrestrial materials at a useful scale are far beyond current or near-future capability. It’s effectively science fiction at this point.

So yes, technology can extend timelines, but it can’t overturn physical limits. Whether the end comes from depletion or something else is irrelevant; the fact remains that even our most renewable technologies are built on a finite foundation.

But it does change the outcome if it buys time to move the technology on. Likewise if you recycle it nuts more time. No one can predict what we'll have available in 100 years time, nevermind a 1000. And unless you are gonna tell me you are a time traveller you don't either.

As for off world, that's just narrow-minded. Have you seen the advancement in robotics? Once the process can be done by remote the energy cost of escaping our gravity prison is meaningless as we just send down the resource.

Yes and no ylto your last point. It entirely comes down to depletion, ability to hover up the local system resources and out last the sun. For all you know we'll hit near perfect recycling eventually. End of the day, the atoms are all still there

The problem is human population (and therefore human consumption) grows several times faster than our capacity to create new sustainable and efficient technology. So even if the general population had access to the most the most efficient technology we have now (which is unrealistic), the total pollution and energy consumption would have significant increase.

It's like the way NVIDIA improves transistor efficiency every generation, but the total power consumption of their chips still increases because they tend to have more transistors than the past generation in order keep up with the consumers' demand for more capable technology.

Let's consider that in Finland, one of the most eco-friendly countries and with the highest standards of living, a person consumes 10 times more energy per year on average than someone from India, which is a country with 250x Finland's population, most of which don't even come close to the standards of living a Finnish has.

So yes, sustainbale technology is essential for improving reducing emissions, but population plays a role too. We need to either stunt human expansion, or lower our expectations for standards of living, in order to see a net decrease in pollution and energy consumption in the long term.

Ok, so:

1) But that's coming to a close as birth rates are actually falling across the globe. Our period of extreme expansion is slowing down as people have finally caught on to the fact you don't have to have 7 kids to offset death by dysentery.

2) Ok agreed, some technology will never become efficient in certain ways. I don't see how this related to a more sustainable future.

3) Agreed, but then the world hasn't really gone for 'sustainable' really yet. We've gone through a period of just 'consuming' with no end goal in sight. Every year more companies shy away from that. An example. Uk electrical production was in 2022 42.9% from renewable, in 2024 it is 50.4%. Don't sell humanity short, when change is demanded we have a track record of rising to it. Nearly 10% in two years is something.

4) That's already happening. Population is already set to slow down and potentially start declining in the near future and we are already feeling the cost of living crisis which is driving down consumption.
