Interpretation
Environmental Impact Interpretation
We are a world-building civilization whose most essential modern ingredient, alumina, comes with the utterly absurd business card of being 95% reliant on a process that, for every ton of product, also produces up to three tons of permanently toxic red mud and requires a global industry CO2 bill of over a billion tons annually, yet we are somehow also clever enough to be recycling most of our water, recovering most of our energy, and even beginning to turn that insidious waste back against itself by using CO2 to tame it.
