The birth of modern plastic began in 1907 with the invention of Bakelite, one of the first plastics to be made from entirely synthetic components. But plastic in a particular form was being used many thousands of years ago by the Olmec, the earliest known civilisation in Mexico, who played with balls made of a natural polymer - rubber. Over the years the plastics industry has grown from the work of a handful of inventors to a global player whose products reach into almost every corner of our lives. Plastic has been at the heart of one of the most important changes in virtually all societies since the second world war: the consumer revolution.
But while it is a force for good in many areas and a highly versatile material that appears in the most surprising places, plastic today is a major environmental preoccupation. Can we modify our use towards this wonder material, or can scientists rise to the challenge of creating a plastic that will break down completely when it has reached the end of its useful life?Rajan Datar is joined by nanoscientist Professor Ajay Mishra, chemist Professor Andrea Sella and journalist Susan Freinkel to explore the story of plastic.Photo: Plastic bottles on a production line (Getty Images)
