Susan Masino, a professor of neuroscience at Trinity College, stresses the link between healthy brain metabolism and nature. I don’t think there are many of us who would deny that joy that one feels by taking a walk in the woods. However, Susan explains to us how and why we need that type of experience to maintain our health and sanity. Forests are not something to be exploited for purely commercial gain. Forests, and nature preserves are a necessary component of a healthy society, and planet.
