We all take for granted the idea that being in nature makes us feel better. But if you were a skeptic who wanted hard scientific evidence for this idea, where would you look? And how would that evidence be gathered? It wasn't until Dr. Kathy Willis was asked to contribute to an international project looking for the societal benefits we gain from plants that she stumbled across a study that radically changed the way she saw the natural world. In the study there was clear proof that patients recovering from gall bladder operations recovered more quickly if they were looking at trees. In fact, in the last decade there has been an explosion of "proof" that incredible things happen to our bodies and our minds when our senses interact with the natural world. In Good Nature, Kathy Willis takes the listener on a journey with her to dig out all the experiments around the world that are looking for this evidence. What is remarkable about this book is how its revelations should be commonsense—schools should let children play in nature to improve their health and concentration; urban streets should have trees—and yet it reveals just how difficult it is to prove this to businesses and governments. As Kathy Willis says in her narrative, "Nature is far more than just something that is useful for our health. It is not a dispensable commodity. It is an inherent part of us."
