Horizon - Man and Science today

The farms and factories of the thrusting western nations have doubled and trebled their output in a decade. But many scientists warn that increasing production and increasing population threaten the world we live in. Waste products, already a nuisance in densely populated areas, could be a danger in the foreseeable future, poisoning the air we breathe and the water we drink.
A Horizon unit has filmed scenes in parts of Britain where pollution is a problem now, and a possible menace tomorrow. In the studio, representatives of science, industry, and government discuss their attitudes to these examples of an environment under attack.
