 - videocassette (VHS)(32 min.) : sd., col. 1/2 in. 
<br/><br/> Virtually everything we take for granted is of quite recent origin. A hundred years ago the modern world had no steel, no electricity, no cement worth talking about. Even thirty years ago, the whole scale of our economic activities was relatively harmless, non-destructive. It's really only in the last thirty years that all our natural assets have been threatened. Economist Dr. E. F. Schumacher, author of 'Small is beautiful', presents this programme on the necessity of maintaining the health of our forests.
