An image to highlight the need for the sensitive use of all materials particularly those that have been discarded as waste . As the world increasingly grapples with the problems of diminishing resources and the ever increasing demands for food, energy, water and clean air, we need to make radical changes to the way we live in order to create a sustainable model. This image uses the nest as a symbol for the home ; it is made from mud and straw but also interwoven with electrical cables , copper wire and plastic. The eggs are a promise of a future on the blue planet .
