The whole world needs to realize that populations and economies can't keep GROWING as if the planet is infinitely large. Most of those dreaded "sacrifices" involve acknowledging limits to growth, and they'd be intelligent choices, not losses. But greed wins over intellect most of the time.

We've gotten away with growthism for over a century but it's just not physically possible for it to continue, especially as fossil fuels peak and decline (not a matter of if, but when). This also includes "clean" energy which needs fossil fuels to exist and can never match the scale of fossil fuels alone. Just as importantly, it ends up ruining vast areas of land and sea, e.g. industrial wind turbines.

Want an actual solution? Look into a steady-state economy.
