We are getting near the end of looking at Holmgren’s 12 Principles of Permaculture with this episode on Principle 11: Use Edges and Value the Marginal. After a brief introduction to what each one, numerous examples are given. There are a number of homework assignments as well. Give them a try and see what you learn in the process.
Also mentioned in this episode are Phytoremediation and the work of Paul Stamets, who is working with fungal mycelium as a way to handle pollutants. Here is more information on both for sources that I like.
Citizens Guide to Phytoremediation (PDF) This is a simple 2-page overview of the process and is good for letting people know this option is available.
If you go to: www.clu-in.org and search for Phytoremediation a number of articles are available.
This is his TED Talk. At 18 minutes long it is worth your time.
