In this program, James Lovelock explains the development and evolution of his Gaia hypothesis, which considers the Earth as an intimately linked system of physical, chemical, and biological processes, interacting in a self-regulating way to maintain the conditions necessary for life. He discusses counterarguments proposed by scientists including Richard Dawkins. The Daisyworld climatic prototype is explained in detail through scientific computer graphics and animation. Produced by the Open University. (25 minutes)
