While it's true that all that wasted energy and squandered precious rare earth elements and belching coal smoke and CO2 greenhouse gasses and climate change and cancer and lung disease you create by making NFTs are something bigger than yourself, they're not necessarily what you want to be remembered by.
And any person receiving some random amount of money donation from Facebook in exchange for NOT making an NFT probably cares.
Or is your whole point "who cares about the environment"?
