This is an audio link to the 2nd hour of the Diane Rehm show on NPR today. While it is not explicitly vegan-oriented, it's an important piece to listen to and relative to animal rights/liberation theory, as well as containing other social/political issues(gender-ie "manliness", environmental, health, etc.)

Click on link below. Scroll down to "11:00 Environmental Outlook: Freshwater Fish" and choose either Real Audio or Windows Media to listen. It's an hour long.
