In this two-part documentary, Oxford Professor Richard Dawkins examines how religious faith is gaining ground in the face of rational, scientific truth. The program takes you to some of the world's religious hot-spots, both in America and the Middle East. Dawkins meets with religious leaders and their followers, as well as scientists and sceptics to examine the power of religion. Interviews with former Pastor Ted Haggard, the novelist Ian McEwan, the former Bishop of Oxford, and others offer valuable insights into the global impact and consequences of faith in the 21st century. Along with his million-copy bestseller The God Delusion, Richard Dawkins' Root of All Evil? has helped inspire people of reason worldwide to say "Enough is enough!" Our modern world is the product of a long march from ignorance and fear to the Enlightenment and beyond, always guided by the power of science and reason. To now abandon our endeavour toward progress and knowledge for faith and superstition puts humanity in peril.
