Don't you just love that word... Stromatalites... I don't get the chance to use it that often so i like to savour the opportunities when I do. I used a pic of them, these strange shapeless rocky nodules growing on a shallow sea in a talk I give on the Introduction to permaculutre course at the Workhouse the other weekend. They are not exactly the oldest living organisam on the planet, but they are crucially the very first ones to breath in Co2 and breath out oxygen. They turn up in the fossil record about 3 1/2 billion years ago, and were widespread around the globe. You can still find them in certain special places, like off Western Autralia. Before them there was no oxygen in the planet's atmosphere, we have a lot to thank them for, as oxygen breathing organisms ourselves.
I want to thank everyone who came on the Permaculture course at the Workhouse, the first of what I hope will be many we do there. Its kind of interesting running one in the shell of an empty building, right at the beginning of a new project. A blank canvas to apply your imagination to.
we are planning another permaculture weekend in March, and a yurt making weekend course in April, again both at the Workhouse. I am currently posting information about m courses and project on the Sector39 website, the which is the permaculture design team i work with to develop courses and permaculture projects.
