There is not much anyone can do TBH. Too much of the social/political/monetary systems we currently live in have exponential growth baked into their values. It's incredibly hard to turn that around. Now there is work being done on building a different economic system but its anyone's guess if the current system will bend itself into that direction or it just breaks and the new system fills the void. But either way capitalism is dying and there is no hope of saving it.

I recommend organizing and building up dual power.
