I really enjoyed this book! Having recently moved from a single family house that was poorly insulated into a smaller high rise, where you never even need to turn on the heat, it made a lot of sense to me. However, my moving here displaced someone else, so were there really any gains in sustainability? I've lived in NYC and Boston, both cities rank high on the green index, with NYC using the least amount of energy per capita. As energy prices rise, green building is going to be more affordable and desirable. As the author points out though, it is difficult to really be able to tell how much energy is being used to produce a certain product. Especially where food is concerned. People talk about buying locally, but a truckload of berries that travels across the country may be more efficient than driving 10 miles to a local farm stand.
Definitely recommended for ecologically minded readers!
