One of the problems with industrialism is that it's based on the premise of more and more. It has to keep expanding to keep going. More and more television sets. More and more cars. More and more steel, and more and more pollution. We don't question whether we need any more or what we'll do with them. We just have to keep on making more and more if we are to keep going. Sooner or later it's going to collapse. ... Look what we have done already with the principle of more and more when it comes to nuclear weapons.
