>The other thing I don't entirely get -- and I am not entirely sure I want to know -- is why penguins. The article highlights that they're a bad "oil" animal. Because they're so easy to catch. Also,the advantage (from a purely economic, not moral or ecological, point of view) of using wild marine animals for this is that you don't have to grow fodder for them or even set aside land for grazing. Penguin eggs are still eaten in the Falkland Islands, though AFAIK commercial harvesting is illegal. Apparently the white remains translucent even when hard-boiled.
