Not sure what plastic sushi means but what’s hypocritical? Because proof of work networks, like Bitcoin, are energy intensive? Ethereum is in the process of converting its network to proof of stake (most newer blockchains are not proof of work so involve much less energy than, say, Google’s server farms, banks, Amazon, and such). Or do pictures of vaginas hurt the environment in ways I don’t grasp? I ask in all sincerity as I’m not sure I understand your question.
