I've been a life long advocate of organics and sustainable survival this would include Permaculture. It seems to me the fundamental issue at stake at the moment is to reconnect with the natural rhythms of life which also includes an everyday culture which reinforces this connection.
As someone once said 'Downsizing the screen doesn't change the movie' and though reducing your carbon footprint is commendable there has to be more depth than just that.
I currently live on a property near Murwillumbah which is on the edge of the Northern Rivers in NSW and am developing (hopefully) a system of living with the land and not just on it or off it!
My main interest is discovering/developing systems which are easily implemented that imbibe the natural systems already existing in the locality so an example would be growing plants that suit the particular climate of the locality in an actual spot that is the optimum site for that plant's survival.
Soil conditioners such as bio char mulch, wood chip etc are used if easily available or made. Every site has it's plus aspect and of course a downside so study of the landscape for about a year is highly advocated, this helps to reduce plant failure.
The property I am currently on is very stoney so initially it was difficult to garden but the plus side was I built the foundation for a hundred metre track with the thousands of stones I pulled out of the ground
