Give it to a group like Just Stop Oil or other direct action / sabotage focused climate activism group - they’re perpetually broke and could do a lot of good with that money.

Did someone say “One Big Union”? Sounds like the IWW would be right up your alley. It’s coming back to life again - definitely check if you have a local branch!

The IWW is an explicitly radical militant union devoted to overthrowing the tyranny of the wage system and settling the class war through full worker control of all enterprises. It’s an entirely different animal than the bloated business unions who settle for a “fair share” of the profits. The IWW asserts that all of the value produced by the labor of workers should go to workers, and the bosses can become workers like the rest of us.

Both Just Stop Oil and Extinction Rebellion are great, and protests should be disruptive, otherwise they’re just ignored. Maybe they’re not doing enough disruption and damage to force governments to listen. Or, maybe someone should go after energy/oil companies directly via sabotage or other means and cause enough economic damage that the cost of polluting and resource extraction becomes too high for them to profit from.
