Cradle to Cradle Commentary I and home design

Cradle to Cradle is an excellent book for anyone to read would be interested in opening their perspectives into Zero Waste.  I have found it very similar to the information in the You Tube video "The story of stuff".  However it goes further in discussing the thought process behind producing products in an sustainable way. For instance Clay homes that have been built by other cultures that retain heat in the winter and coolness in the summer has never be considered into the design of homes in the U.S.  While it may not be practical for some climates, notably the much colder ones, just getting the thought process started as to how other cultures have dealt with extremes in climate while living sustainably, would be worth while for future home designers to consider in the evolution of home design going forward.
