Episode description

The story of how the search for a material to replace ivory changed our lives forever. In the 19th century a billiard ball company placed an advert in a newspaper offering $10,000 to anyone who could come up with a substitute for ivory. There was growing concern that companies were hunting elephants into extinction so they could use their ivory for billiard balls, buttons and umbrella handles. The story that follows takes us from explosive factories that often went up in smoke to the modern world we find ourselves in today. How did plastics go from being a saviour of the environment to a cause for concern? How did we get hooked on plastic?
