James Martin, one of the world's most widely respected authorities on the impact of technology on society, argues that we are living at a turning point in human history. 'We are travelling at breakneck speed into an era of extremes - extremes of wealth and poverty, extremes in technology, extremes in globalization. If we are to survive, we must learn how to manage them all.' Although we face huge challenges and conflicts, Martin argues that it is in the scientific breakthroughs of the new century that we will find new hope. In a clear, penetrating and insightful style he addresses the key questions of our age and proposes an interconnected set of solutions to its problems.
