I just watched The Cove about the annual slaughter of dolphins in Taiji, Japan. Please watch it. It's the story of a group of rogue environmentalists waging a guerrilla campaign in enemy territory to expose Japan's dirty little secret.
I used to think this South Park episode (full episode at link, relevant clip below) was a joke, or at least overstated. It's not.
Taiji was hit to a small extent by the tsunami, but none of the dolphin killers' boats was destroyed and the slaughter is expected to resume this fall.
