Alice Waters and shark fin soup

Alice Waters has gotten into pr trouble by stating that she’d want her last meal to be shark fin soup – apparently unaware that sharks are caught, had their fins cut off and then are thrown back into the sea to die. Now that she knows, she’s changed her mind.

It seems a bit surprising that she wouldn’t know about the horrible treatment of sharks in the first place, but then again – how much of the food we consume is from animals that have been horribly treated? Sometimes I think the only ethical choice is to be a vegetarian – too bad I don’t like vegetables.
