The Vice-President of the Conservation Foundation in Washington, DC and renowned ecologist Sir Frank Fraser Darling explores the concept of Man's responsibility for his natural environment in his Reith series entitled 'Wilderness and Plenty'. In his third lecture entitled 'The Technological Exponential', Sir Frank Fraser Darling examines the ecological consequences of technology since the industrial evolution. He reflects on the way the rapid guzzle of oil, coal and nuclear materials has affected the environment and touches on what this technology has done to Man as well. He scrutinises the enveloping character of advanced technology, and the choking side-effect of pollution.
