In 2011 the world's population exceeded 7 billion. Each year we add nearly 80 million people and by mid-century we will require twice as much food and double the energy we use today. Australia will be deeply affected by these trends - we have the fastest growing population of any developed nation. These are the staggering facts that confronted Dick Smith. They set him on his crusade to alert us to the dangers of unsustainable growth. They are the facts that have convinced him that if we are to ensure the survival of our civilisation and the health of the planet then we must put a stop to population growth, now. As our cities continue their unrestrained growth, as we battle daily on crowded public transport and clogged freeways, and as we confront the reality of water and power shortages, Dick challenges the long-held myth that growth is good for us. But more importantly he offers ways for us to reinvent our economy, to reassess the way we live and to at least slow down that ticking clock. This is a provocative, powerful and urgent call to arms.
