"Ethics, Economics and Posterity," presented to the Virginia Tech Worldwatch Symposium, November 8, 1991. The symposium series was started in response to the Worldwatch State of the World Report in 1990 that gave us 40 years to put earth on an enviromentally sustainable basis. It seems to have been right on target, as a 2018 UN report gives us only 12 years, and wonders if it is now too late. This paper constitutes my response to the economist's view of the world.
