Distributed Wastewater Management: The More Sustainable Strategy

摘要

What do we mean by sustain-ability? Clearly, nothing is sustainable in an absolute sense. Even life on Earth, which will end in about 5 billion years, according to the best science now available, when the sun, expanding in its death throes, leaves Earth as a lifeless cinder. Much closer at hand, the specter of "peak oil" implies that many practices of our oil-fueled society cannot be sustained. So it is clear that nothing is absolutely sustainable - entropy never sleeps.
