Sustainable firewood

Sustainable firewood

A lot of activities get labelled as 'sustainable' these days, despite having a hidden subsidy of non-renewable resources or energy. The only truly sustainable energy source is the sun and the various manifestations of that energy such as biomass, wind etc. The rate and method (technology) used to harness or extract that energy determines it's long term sustainability. Wind turbines constructed from huge volumes of concrete, steel and carbon fibre are not sustainable while harvesting a tree with a stone axe is sustainable if practised at a rate that permits regrow under local ecological conditions.

Note: I used a pseudo sustainable electric chainsaw rather than a stone axe to dissect this manuka tree. It will be replaced by a five finger (Pseudopanax arboreus), already growing up out of the decaying stump.
