This is a book to accompany the BBC Series of the same name and if you had all the resources, particularly the land, to start with, you too could do some of this. It has some interesting ideas and some bits and pieces that almost anyone could implement but a lot of it requires resources, particularly that of people. Doing the TV series helped the Strawbridge family in their quest to live a more eco-friendly life but also their boundless enthuaism and ability to think laterally.
More of a diary than anything else it's a fun read that almost sounds like Dick Strawbridge does on TV (I haven't seen this series but I have seen him, and his son on other programs). It has hints but if you're looking for ideas to move that way yourself unless you have land and resources it's not that useful. Entertaining yes, educational not so much.
