The last public message recorded by Sir Arthur C. Clarke

This was the final public message recorded by the late Sir Arthur C Clarke, which closed the global launch of the International Year of Planet Earth, at UNESCO Headquarters in Paris on 13 February 2008. In his unique style, Sir Arthur connects the local with global, and traces the influence of space exploration on the global environmental movement. He ends calling for humanity to listen to the planet's distress call, and respond with knowledge, understanding and imagination.
