John Wilson explores the reasons why some artists use rubbish in their work.
Picasso, Dali, Georges Braque and Joan Miro all used discarded objects in their art, and in the last few decades there has been an explosion of artists using 'found objects' in their work to communicate many different messages about waste, consumerism and the dispensability of modern life.
Some artists are campaigners and artists in equal measure. John meets Fran Crowe, who creates installations and engages in performance art with the rubbish she finds on the beaches near her Suffolk home. He also talks to Sir Peter Blake, who celebrates litter and tries to create something of aesthetic value from it, and sculptor Gavin Turk, who looks for the beauty in objects that have been thrown away.
