How to rebuild the world from scratch (Lewis Dartnell)

Maybe an asteroid hit Earth. Perhaps a nuclear war reduced our cities to radioactive rubble. Or an avian flu killed almost everyone on Earth. However it happened, the world as we know it is over and we must start again. So how do we set about rebuilding our world from scratch? How do you grow food and make clothes? Or generate energy and develop medicines? Lewis Dartnell will help us, as the survivors, reconnect with the basic skills and knowledge which our lives and world depend upon. By taking us on a journey of rediscovery, he will transform our understanding of the world.
