I came across a fascinating essay about permaculture and energy descent in Mexico that introduces me for the first time to the existence of so-called permaculture punks in Mexico City. Its author, Holger Hieronimi, has spent the last seven years developing a permaculture based homestead there- so he knows the difference between theory and practise. The picture above, which shows a stage in the construction of an anaerobic digester, is just one among a whole sequence of fascinating visual stories. I also never heard of bocashi composting, either, until today.
