I think you have a bit of a point though you know very well that most people will never voluntarily choose your lifestyle and you make some contentious statements. However - we do have the largest population of humans ever, often located in dense cities and we've covered our Earth in concrete and asphalt to an extent such that its mass (since 2020) now exceeds the total biomass on Earth including ourselves (our bodies). https://doi.org/10.1038/s41586-020-3010-5. Our attention to the problems of providing appropriate infrastructure to support this desired expansion is evidently very patchy. That's certainly true for instance with the issue of the water shortage in the UK which is certainly a political failure. In view of the above why do we expect the environment to adjust itself with a view to our best interests and why are we shocked when it doesn't?

The "puzzles" will keep pilling up. One year there will be no insects, the next year it will be a horror movie. Global human-made mass now exceeds all living biomass [0]. We are basically simply pushing the rest of the biosphere to a corner. It responds as the immensely complex, adaptive, system that it is: unpredictably.

They didn't even try to imagine it though. According to the linked article[1] there's about 1.1 Tt of concrete on the planet. At a density of 2.4t/m³ that's 458 billion m³ or 458km³. That'd be a cube of with a side length of 7.71km or about the height of Mount Jannu[2] from ocean level.

Not on the right order of magnitude. We need to reduce our material consumption and energy consumption, even keeping them to the present level would not be sufficient, so for what you're talking about we'd need absolute decoupling, and that won't happen through efficiency gains, I'm willing to take that bet any day (and without even invoking Jeavons' paradox). https://eeb.org/decoupling-debunked1/ PS: this was this week's latest paper that helps comprehend what exponential growth means: https://www.nature.com/articles/s41586-020-3010-5

So if it isn't plastic made from fossil fuels, what do you suggest? Apparently the global human mass excluding humans themselves who comprise 0.01% of the global biomass but including our constructions in concrete, asphalt, aggregates, bricks, plastic & glass exceeded the global biomass back in 2020. The same report claims that this anthropogenic mass doubles every 20 years. I wonder what the thermal capacity of all this is let alone other manifest concerns. https://doi.org/10.1038/s41586-020-3010-5
