The difference between disextensification (better name urgently needed) and degrowth is the difference between “doing more with less” and “doing less with less”. The former views the un–sustainability of economic expansion as primarily a practical, the latter as primarily a moral problem, and that in turn reflects the question of what value we place on human life and welfare. Also, is “building the world’s largest aeroplane for a single narrowly–defined purpose” an invariable sign of an idea that has been taken too far, and fallen into absurdity?
