During the 20th century, humankind has managed to do the impossible: we have brought famine, plague and war under control. Today, more people die from obesity than from starvation; more people die from old age than from infectious diseases; and more people commit suicide than are killed in war. We are the only species in earth's long history that has single-handedly changed the entire planet, and we no longer expect any higher being to shape our destinies for us. As the self-made gods of planet earth, which projects should we undertake, and how will we protect this fragile planet and humankind itself from our own destructive powers? Yuval Noah Harari examines the implications of our newly acquired divine capabilities, from our desperate pursuit of happiness to our dogged quest for immortality. As our gods take a back seat, and Homo Sapiens becomes Homo Deus, what are we going to do with ourselves? How do we set the agenda for our own future without pushing our species - and the rest of the world - beyond its limits? This book examines the implications of our newly upgraded condition, from our dogged pursuit of status and happiness to our constant quest to overcome death by pushing the boundaries of science. It explores how Homo Sapiens conquered the world, our creation of today's human-centred environment, our current predicament and our possible future. And, above all, he asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers?
