Here’s a short interview with Sea Shepherd Captain and Whale Wars star Paul Watson, which includes this response:
I run my ship as a vegan vessel. It’s not for animal rights reasons but to set an example and to try and get people to think about the connection between what they eat and what we’re doing to the oceans, because it’s quite simple, really.
The interview concludes with recipes for three Sea Shepherd mainstays: pancakes, banana bread, and chili. Link.
