An economic system that is predicated on perpetual growth and resource extraction will eventually collapse as there is no more growth or resources to extract. Everyone is tapped out and there is nothing more you can squeeze. So it’s not surprising that the people on the lower end of the economic pole are taking what they need to survive, if the economy can’t provide for your basic needs then fuck the economy.
Agreed geoengineering is bad science/engineering IMO. You can’t know what the long term effects would be until after its been deployed. The safest bet would be to just ditch fossil fuels but that’s not as sexy.
