Marc Berman is out to start a revolution. I am already a convert to his cause – and you may be too, having read in New Scientist about the extraordinary benefits of a nature walk, the healing power of plants and the magic of urban green spaces. If so, perhaps you will think there is nothing to be gained from a book about Berman's research. Nature and the Mind is for everyone from the adept to the uninitiated – it isn't simply written to educate and entertain, it is a call to action. This is the story of how an anxious boy, warned off studying medicine by his mother, a nurse, and law by his father, a lawyer, enrolled as an undergraduate in engineering and then went on to establish the revolutionary field of environmental neuroscience.
