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 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.
