THE DROWNED WORLD by J. G. Ballard
In a future in which solar flares have wreaked havoc with the earth's atmosphere, Dr. Robert Keran leads a scientific mission to survey the drowned citites in what was once the temperate zone before they are abandoned for good. The de-evolution that the ecological crises has provoked seems to have affected the expedition's crew. Keras, alongside his enigmattic lover Beatrice, is trying to make sense of the disappearance of a crew member who has succumbed to the lure of the emerging new water world. Ballard's vivid futurescape imagines the surreal results of Darwin's theories going into reverse. A BBC Radio Drama.
