A year or so ago I saw a video where Geoff Lawton (I think?) went down to Haiti (I think?) and helped with disaster relief after a massive hurricane left thousands of people homeless & without water or sanitation. He built round huts out of plastic bottles and cob, somehow including water cachement. It was an inspiring demonstration of reusing waste in a productive and helpful way.
But I've googled til my eyes bleed and I can't find it anywhere - anyone know where it is, or the title at least? Is it one of Lawton's own videos, but under a title I might not associate with the subject?
My architect dad is very interested and I've spent all evening sharing Lawton's other videos and informing him of other basic permaculture principles.
