This book re-writes the script. Studying a degree in Product Design at Central St Martin's completely convinced me that designers are all moral-less, capitalists twits and this book actually made me reconsider that view!
The basic premise is this: We can design ANYTHING we need to be COMPLETELY sustainable.

Now that just about re-writes the design brief of everything that has ever been made and implies if it isn't 100% sustainable it has failed the fundamental design challenge.
