Cradle to Cradle

Cradle to Cradle introduces the transformation of human-centered activity to the environmental-centered activity. They have lists of things that people could do in order to improve the environment. They also proposes "upcycling"--making used materials more valueable--instead of "downcycling"--what we are doing right now. I think that the book contains a lot of good points. However, at the same time, I also think that they did not include the explanation of well-designed strategies that illustrates the process of these proposals. In other words, they did not state clearly that "how are they going to do these?" Thus, it seems to me that the proposal is a utopian concept. However, I still feel that the proposal is do-able under such high-technology. They need more interpretation, variation, and experimentation to improve.
