But you have to grapple with the counterfactual. The status quo of not building some of these projects is we keep pumping tons of coal soot and gas fumes into the air. We are currently on course to destroy the ecosystem of the entire planet.

I won't pretend that I know these projects are well-sited or they couldn't easily be done in a better way to lessen their impact. But, you can't use "it has a new harm" as an a priori veto of changes when the status quo is so deeply, deeply harmful.
