The problem is not that individual action is not useful, it’s that governments and companies are actively discouraging it, because every success for climate change is a bad news item. People buying less cars? Climate change win, economic problem. People buying less stuff, consumption down? Huge climate change win, very bad economic news. Even on progressive news outlets they’re doing it.
Here in Europe even before Trump’s second mandate it was clear governments didn’t really want individual action to take off. And it’s even worse now. Because short and mid term it’s a choice between climate and GDP. And western governments and companies are fundamentally incapable of long term action that is painful short term.
