How would you like to live in world where we humans produce an abundance of food and revitalize the life around us? A world where our species plays a key role in increasing rather than decreasing biodiversity, where we store more carbon than we emit? Where we reverse dead-zones and topsoil loss, and where diet-related diseases become exceptions, not the norm?

This world is not a fantasy: it is the future. All over the northern hemisphere, humans once tended nut trees like oaks, chestnuts, and hazelnuts to produce abundant food and in doing so created thriving ecosystems for countless other species. Join Elspeth Hay, author of Feed Us with Trees: Nuts and the Future of Food, to learn why it's time to bring these nut trees back as staple crops, and how in tending our keystone nut trees, we can revitalize our world.
