Learning to Glide, When Flying High is No Longer Possible

For a long time now, we have been flying high, as individuals and as a society. Metaphorically, in the sense of living well while drawing down the earth's ecosystems; and literally, in the way we just hop on a plane for the smallest of reasons. How much longer can we or should be flying so high, and what might we gain from learning to glide instead?
