This book addresses the survival of humankind. Our world is the best it has ever been, but it is not sustainable. It is self-destructive; it is marked by war, which can destroy the world in a single day, the destruction of natural and human capital within 10 years, and technologies which could be both beneficial and destructive. We have no future if we continue living as we do currently, and even if we do nothing. This book highlights the kinds of changes which are required. Wars are not biologically necessary and are useless; the culture that established wars can eliminate them. Poverty, hunger and inequality destroy human capital. These destructions can be overcome by changing economic and political paradigms and our mindset. Empathy, freedom, curiosity and wisdom are required.
