In this expanded version of an inspiring speech delivered in December 2009, David Suzuki reflects on how we got where we are today and presents his vision for a better future. In his living memory, Suzuki has witnessed cataclysmic changes in society and our relationship with the planet: the doubling of the world’s population, our increased ecological footprint, and massive technological growth.

Today we are in a state of crisis, and we must join together to respond to that crisis. If we do so, Suzuki envisions a future in which we understand that we are the Earth and live accordingly. All it takes is imagination and a determination to live within our, and the planet's, means. This book is the culmination of David Suzuki’s amazing life and all of his knowledge, experience, and passion — it is his legacy.
