I think MrSmith said it earlier in the thread... if you're truly serious about limiting your footprint on this plant, cut to the chase and kill yourself. Anything less than that is selfish to some degree, so really the point is that no-one living is really doing everything possible to limit the impact of their existence. So that leaves every single person grappling with ethical debates about where the line is acceptable (to them) between damaging the world by living, and actually living a comfortable lifestyle (you can hurt the world less by not requiring a house to live in).
Close.
Not consuming is where it's at.
