...Interesting interview with Tristram Stuart. Sounds like a very interesting book...
From interview:
Q Do you have a favorite vegetarian?
A Yes, Thomas Tryon . He grew up in the Cromwellian revolution and in 1680 began reading about India, where millions of people were following what he regarded as the original law of God: Do not kill your fellow creatures. He extended that in so many ways that we can recognize now: lamenting deforestation in America; becoming antislavery well before his time; worrying about the pollution of rivers affecting fish and poisoning humans, about soil erosion and cash-cropping in Barbados, where he lived for a while. He is an astonishing character, yet there's no biography of him and virtually no research. I discovered a number of books which had been lost or not identified as his just sitting in library archives.http://chaosinthehouseofcat.blogspot.com/2007/01/vegetarian-evolution-case-of-west.html
