Perhaps slightly dated in its presentation, Bill Mollison's 'In Grave Danger of Falling Food' is still one of the best educational permaculture video's.
"When the western world see's food drops to the starving of Africa, you think it will never happen to us but there is a man in Australia who says that that's where headed"
In this film, the co-founder of Permaculture looks at the modern agricultural systems that put our food security in danger. He then explains the foundations and principles of permaculture and how it can be used to combat a system that it predominantly based on making money rather than producing food.
A classic film!
