Paul Wheaton continues reviewing Sepp Holzer's Permaculture with Kelda Miller, reading chapter 2 on alternative way to keep livestock. Sepp likes old pig breeds, and talks about using pigs around fruit trees and how grazing animals help biodiversity. Paul shares about doing the paddock shift sytem with his pigs. He mentions Allan Savory's wagon wheel method, and how he prefers using more than one animal shelter. Paul mentions Helen Atthowe in his nitrogen fixing comments. The pigs help spread tubers, like jerusalem artichokes. They then talk about cattle, bison, yaks, and water buffalo, and how Sepp feeds them. Sepp talks about how having poisonous plants and mushrooms available to his animals keeps them healthy and away from needing to be wormed. You have to make sure there's enough edible plants around so they don't eat those plants out of hunger. Paul mentions the Wheaton Eco Scale, and how those a few points away from each other think the others are crazy. Kelda shares about the vegan food forest in Seattle. They are glad permaculture is getting some press.
