As someone who is incredibly interested in sustainability and design ethics, I initially will mention that I stopped reading after two chapters out of boredom. Fry talks about things most well-versed designers are already aware of. As someone with a degree in design, I found the information more suited for those entering the design world and its process. The majority of what I read was all rhetoric. A case study every 20 pages (with a jarring switch from serif to sans on the copy) is not enough to make a convincing argument. I found it ironic that Fry pressured readers to think holistically and non-linearly, while he himself would list all the world's sustainability issues and ignore their complexity - things that cannot just be "fixed" with the design profession saying, "Okay"! I sincerely hope this changed further into the book and that people lasted longer than I did while trying to get through the beginning.
This book was published in 2009 and I fear it was four decades too late. Victor Papanek's classic "Design for the Real World" was far more beneficial and well-written. It was less about rhetoric and more about evidence, context and hypothesis. If you have an interdisciplinary design education, "Design Futuring" is probably something you need to pass on.
