Cradle to Cradle: Remaking the Way We Make Things
This is the most important book I've ever read. Cradle to Cradle is a philosophy that calls for humanity to start building and living in a way that is both modern and comfortable and green and ecological. There is no waste in nature, why is there in the way we do things? We should be looking to mimic nature's processes in how we build and do everything. I don't want to live in a cave and this book lays out the future for how we can all do that.
