Cheap, durable, lightweight and malleable, plastic has revolutionised almost every aspect of our lives. But it has come at a staggering cost. Some 335 million tonnes of plastic is produced every year - and at least 8 million tonnes of it enters the world's oceans. It is already the commonest marine pollutant and recent estimates suggest, in terms of weight, oceans will contain more plastic than fish by 2050.
