Multiply and Subdue the Earth
Series Description

Series release date: C. 1967

Program Description

Views the problems of overcrowded cities, air pollution, and the danger of losing our food and water supply. Reveals that most of these problems are caused by unplanned, unwise uses of our natural environment, and the fact that suburban developments are being constructed with little regard for the natural life around them. Explains how 82% of midtown Manhattan’s population exhibits various degrees of mental illness thought to be partially caused by overcrowding, and that man must use ecological planning to seek a unity with nature. Features ecologist Ian McHarg.
