My daughter recently announced over lunch that she would no longer eat any fish. She explained to our raised eyebrows that if people keep up the rate at which they consume the world's fish, the oceans would more or less empty within the coming fifty years.

(Thank you to Jon Rawlinson, who filmed this in one go in Japan, and advises that you give it some time to load before playing to ensure smooth playback. That is, click on play, then click it again so it pauses, and just give the film several minutes to finish loading. My advice is watch it in HD, large screen, to really see these creatures that are grace incarnate. Song: "Please Don't Go" by Barcelona).
