Most of this section is about the 'software' of life: how we behave, as opposed to the technical 'hardware'. The different emphasis on 'technical fixes' and 'lifestyle change' is one of the greatest fault-lines of the environmental movement, and I have been exploring it for several decades.

There are two categories here. One is about the theoretical basis of changing the ways we live, the other about trials and experiments I have carried out myself as a participant observer, which I call 'techno-anthropology' , as if I am a member of some strange modern tribe whose behaviour needs recording, measuring and interpreting.

Having been considering this topic for a long time, it appears that most of the measures required have long been known and to some extent explored by 'enthusiasts'. As a result much of the material here is quite old, because there's not a great deal to add.

Having said this, in recent years there has been much greater interest from the formal research community, and this is extremely welcome. It is sometimes exasperating however, to find academics ignoring decades of actual experience, and starting from scratch as if they just had the whole idea themselves. Oh well, better late than never.
