Marianne Williamson, bestselling author and international speaker

We’re challenged at this critical moment in history to change our thoughts and behavior in significant ways. What we don’t know sometimes is exactly what to do and how to do it. That’s why I love The Sustainable World Sourcebook: it tells us everything we need to know to create a healthier, more just and more peaceful world. It’s a guidebook for going from unaware consumer to passionate world citizen.
