This is a pretty good discussion of the sustainability component of it. I apologize up front for just posting the video connection and not much more. I am terrible at posting videos.

Dave Hamilton (author)
David John Hamilton (born 1974) British author, Journalist, Gardener and Forager.[1][2] Born in Northampton he now lives in Totnes, Devon.
He attended Weston Favell School in Northampton where he slipped through the education system graduating with only three G.C.S.E’s above C grade including English language.
He has lived all over the UK and amongst other things has worked as a market trader in Camden Stables Market and in Anjuna India, a postman and a gardener in Oxford and a driver’s mate and factory worker in Northampton.[3]
He later returned to education and whilst studying a BSc in Nutrition and Food Science at Oxford Brookes he began growing his own food.[4] Realising there were still bills to and full self-sufficiency was very difficult he coined the term ‘Self-Sufficientish’ which later was adopted by the website he runs with his twin brother.[5]
The website led to the publishing of his first book, with Andy Hamilton, The Self Sufficient-ish Bible: An Eco-living Guide for the 21st Century (ISBN 978-0340951026) [6]
He now lives in Devon where he is following another of his passions, that of plants, by training to be a sustainable horticulturist at the Dutchy College run course at the Schumacher College in Dartington. Along with fellow students on the course Dave has started up a sustainable bee keeping group using methods championed by Phil Chandler.[7]
He occasionally appears on TV and radio and writes a regular column for Alan Moores underground magazine Dodgem Logic.[8] He also contributes to Grow It Magazine and Country Small Holder.
