Reducing the Margin

Bill McKinnen, in A Question of Margin:

One way to think about the climate crisis is that we are systematically reducing the margin on which we live on this planet. There were always places where humans couldn’t live: the Antarctic, the centers of the great deserts, the high mountains. But now we’re systematically adding to that list, as places become dangerously combustible, or overrun by rising seas, or just plain too hot. We’re shrinking the board on which we play the sublime game of being human.

McKibben is among the smartest and clearest communicators about the climate crisis.
