Bob, a regular guy from the present, finds himself back in the eighteenth, nineteenth and twentieth century, when humanity was facing some of its most daunting challenges. They hinged on life-and-death issues such as insufficient food for a rocketing global population; the exhaustion of the coal reserves driving the Industrial Revolution; the ever-growing filth and pollution from horse-drawn transport; and, more recently, the increasing likelihood of a new ice-age by the year 2000.Can Bob convince people that this is not the end of the road? Or will he come across as crazy?Nine parts fact and one part fiction, CONVERSATIONS WITH BOB is a witty, clever take on society's enduring fascination with doomsday scenarios. It puts a fresh, historical twist on the challenges of our own time – from poverty and disease to global warming – and leaves us feeling far more hopeful about the future of the planet.
