On our 52nd podcast we hear from Harold Brown, who came to Philadelphia to speak about the global water crisis, and how livestock and citizens, respectively, figure into the equation. Excerpts from his talk, sponsored by Club Veg, are supplemented with a Vegcast question and answer. Then there is a new track from Christina Louise Dicker, the kickass Australian chanteuse, and a Science Fact about the Fountain of Youth, which is another way of saying veganism and exercise.
