Cradle to Cradle

The ideas of William McDonough and Michael Braungart are extremely innovative and pragmatic, but I believe the picture is a bit too rosy. However, while I do believe that their visions are not realistic in the near future, in 25 years these ideas may become more and more of a reality. Originally, I was a bit surprised by the studies used in the book that pointed to everyday household items which were suspected to carry chemicals and toxins that were not only harmful to animals and other living organisms, but were suspected to toxins that were suspected to cause cancer in humans. It made me wonder exactly what the effects of sitting by a computer for hours every day could have on my health in the future.
Setting these ideas up in the beginning and explaining how they can be practically erased (example with the 3 books, gardens on the roof buildings) had me convinced from the beginning. The books methods for reforming companies to transform them from the "cradle to grave" approach to the "cradle to cradle" way of business. The five steps companies could take in order to achieve eco- effectiveness were very interesting proposals and seem like achievable goals in the future.
Although I was impressed with the ideas in the book, I wish the author's would have gone a bit more in depth regarding obstacles to achieving this seemingly ideal society. How exactly would we get by the impediments of those who are content with the current status quo? It seems that many different companies and government officials see no need for change and will hold onto the system that makes them rich. Overall, the proposals seem like realistic goals as long as we can get past those who are committed to the current ways of doing business.
