I'm of the opinion that trying to politically solve any humanitarian issue while the socialeconomic situation is still a clusterfuck would only result in yellow vests burning down your capital while a Trump expy gets elected. Better start investing into sea walls and squirreling away endangered species DNA because it's going be years before we untangle this clusterfuck enough to start slowing the train down
