I can answer to your question as to why. Real environment action would require ungrowth and bankers don't like ungrowth. It means they have less toys. Since the left nowadays is owned by the high finance, they push for shit that makes the environment worse but there wallets happy. Example : let's build more cars than ever with more toxic shit inside than ever and harder to maintain and keep on the road than ever and in the end similar enviro footprints than normal cars but we will call them electrics and green and people will buy them. Other example, and funny fact, ONE passenger on a transatlantic flight consumes as much fuel as 62% of a cars annual fuel usage. So each of this constant and constant travelling by all those people telling me I should bike to work makes me feel unashamed of driving a V8 car. I laugh at the tesla people who think they are part of the environment or something. If you care about the environment you should buy used stuff or things made close to home. Instead of shit that has travelled 5 times across the globe before getting to you.
