Permaculture is a harmonious method of working with the environment using sustainable agricultural designs.  Geoff Lawton from Australia is a permaculture genius.  After watching one of his videos posted on You Tube, we became convinced that permaculture is the answer to many of the world’s food and environmental problems.  We have heard this term now for many years, but had many questions about why it is a brilliant method to grow food.  Geoff Lawton’s videos have answered many of our questions and have caused us to do further research into this method of growing food.  Mr. Lawton is a permaculture teacher who travels the world to educate people how to grow food–even in deserts.  If you would like to visit Australia, he offers classes there too.
