On the other side: Eco systems are permanently changing. We have had cold and warm periods in the middle ages. Most changes are inevitable because bigger systems like the sun play a role. Life forms adapt and find an equilibrium in new eco systems. Nature is stable because it permanently changes. People adapt too, building desalination plants, dams, or isolate their homes for example. Adaption needs energy. The CO2 discussion is about energy: Who is allowed to use energy in the future and at what price. The losers with a low energy budget cannot travel, will freeze in their homes, and will have no purified water. The middle class will pay energy taxes until there is no middle class anymore. The rich will travel around in their private jets and show us in the metaverse how they protect the wilderness.
