I'm still very excited with the concept of permaculture - as Geoff Lawton, one of the leaders of the permaculture movement, says "you can solve all the problems of the world with a garden".
I discovered his videos which are fascinating and very inspiring.
Here is a video tour of the permaculture farm that he manages – it's paradise!
He also offers a series of free videos that introduce the concepts of permaculture that he teaches in his courses:
You can find them at http://geofflawton.com
You might need to enter your first name and email address to access the series of free videos, but I find it well worth it – he definitely doesn't spam you or anything.... Just sends you a glorious new free video every week!
