There is an entrenched system that extracts CO2 from the ground and pumps it into the atmosphere, one that results not from inherent human badness but from the choices of a few humans with power. Confronting that system will take work. We need to build things: wind turbines, solar panels, public transportation, denser cities, fairer societies. We don’t need purification. We don’t need absolution. We need to get to work.
