Swedish contribution to an ecologically sustainable society

Abstract

The conventional water supply and sewage-system needs a change at both a technical and mental level. System ecological thinking is required in order gradually to convert to an ecologically sustainable society, as well as more humility among decision-makers. The Earth is five billion years old. Mankind has been found on this planet for only a couple of million years, but over the last 100 years we have polluted nature and the environment at such a rate that we are approaching a global catastrophe.
