I’m so blown away by the work of John Todd. He works on a huge scale cleaning horrendous toxins out of water. I suspect he knows a bit about permaculture. I saw Bill Mollison’s book listed on one of his websites.
Above is a video that I think gives amazing insight on using plants (and even snails) to clean toxins from water.
John Todd is a genius! Here’s a video we made about him some years back when he was a guest at our PDC where we built a small scale living machine:

Great Video on a wonderful subject. Thanks
Andrew Millison, I love the video you posted. That has been one of my favorites for the last year. Before I watched it, I had no idea that you could test water with living planton to determine the amount of pollution in the water.
