A world without fish?

I do not expect to be dead by 2048, so the documentary "The End of the Line" -- in which it's predicted our world will have nearly completely run out of fish -- scares me. It premiered at Sundance in January and will be shown in cinemas on World Ocean Day. (That's June 8, in case it's not on your calendar.) The trailer follows. Warning: It's powerful and difficult in spots. Get more info -- and an origami skate pattern! -- here.
