I picked this up on a whim from the library since it reminded me a lot of a friend's dissertation topic - I enjoyed returning to some of those thoughts. Chapman's book brings together thoughts on design, sustainability and psychology. His thesis is that consumerism damages the environment because of how prone people are to throwing away products. The physical durability of our products isn't the problem - plastic will last for thousands of years. Instead, it's the emotional durability of our products that is letting us down. Chapman believes that designers should design their products with features that are conducive to evoking our empathy. By fostering relationships, with spontaneity and mutual fulfilment, we would be less likely to discard functioning objects.
Chapman belabours the point from time to time but I think his thesis is correct. Either way, his program has great potential for inventive design that is also beneficial for the environment. There's images and descriptions of existing designs that exemplify his principles scattered throughout - but he doesn't discuss any of them which I feel was a missed opportunity. BUT - I think any anyone interested in creative pursuits should read this.
