I’m pretty sure that’s not remotely true. Look at the state of the Ganges River or the visibility in any major Chinese Metropolitan area. Many countries just ignore these patently obvious ecological disasters. The notion that climate was in a pleasant homeostasis until European people arrived is absurd on its face and contrary to geological record.

You are being scammed. Billionaires just want an excuse to assert control over all human activity. Climate Doom is an eschatological religion for atheists. Conserve forests, control industrial waste, substitute toxic products, of course. But your breath is an existential threat to all life on Earth? It’s ridiculous and it has completely derailed productive environmental efforts with carbon-trade scams and a regulatory priesthood demanding sacrifice. Meanwhile serious people can barely get a hearing on aquifer depletion, topsoil loss, overfishing, food quality, or source water protection.

Exhalation accounts for maybe 10% of co2 activities. But our carbon comes from what we eat which is in a loop with photosynthesis. It does not accumulate in the same way emissions do.

Meanwhile we add 10x of that every in a system that does not have a drain for it.
