ABSTRACT
Civilisation is now so advanced that it is possible to study in considerable detail the Earth and the Universe, an exciting and stimulating endeavour. Scientists can examine the Earth at all scales, from the subatomic using high-energy particle physics to cosmic scales using the most sophisticated telescopes and spacecraft. Images of Earth from Space are now familiar to all (Plate 1). Sophisticated global climate modelling and predictions about future climate change are becoming commonplace. With such technological advances and the wealth of opportunities for monitoring the natural world there is little excuse for any profligate use of raw materials and environmental degradation.
