would have had some foresight regarding an non-replenishable resource. Stretch out and conserve its use, ban wasteful retrieval, production and usage, forecast the point of rational profitability and heat sink damage.
If we had even curbed the economic vampirism and general usage to last easily a few hundred years, perhaps the climate change scenario would have been slowed or even entirely mitigated. Certainly it would have given humans time to evolve and handle the problem and historically- if not genetically- change.
Instead, in a mere century of brutal waste and economic decadence we have blown through the easy stuff with unfortunately just enough tech advancement to squeeze more damage and keep full denial and the giant economic gas bubble. Climate change moves parallel to economic apocalypse maybe at a slower but more inevitable pace. Also when an easy alternative energy and carbon resource might be needed it will simply be gone for eons.
The big picture shows a relatively fast and relatively unchanged(even that which is theoretically under human control) catastrophe that to a large extent has already happened.
