When it was launched, plastic was a miracle, the undisputed material of the future. Wood, stone and cloth were all finite, so a new, cheap and easy-to-handle material was needed to manufacture goods. More than a century later, it would be impossible to imagine our society without plastic. The miraculous material isn't only the raw material for goods and packaging, but also for art. On a trip that spanned three years and five continents, Ian Connacher investigated the impact of so much plastic. After all, the material has a major drawback, as it isn't biodegradable and doesn't get recycled in most countries. This means that the majority of the plastic made in the past century is still stored somewhere on earth. Connacher reveals that traces of the material are even to be found in the stomachs of marine animals, which means that plastic ends up in the food chain. We also learn that plastic might not be as harmless as people originally thought. But there is hope, as a number of companies are putting a completely biodegradable plastic on the market. Nevertheless, the traditional plastic industry is powerful and won't give up its position without a fight.
