Reef ecologist Jeremy Jackson's April 2010 TEDTalk illustrates blindingly the fact of overfishing, if we still needed evidence to convince us to stop ripping the guts out of the world's oceans.

The trophy board at Key West in Florida shown here in the 1950s and in the present should do the trick, right?

The bottom photo was taken, say, 55 years ago "from the same boat, in the same place, on the same board, on the same dock. The trophy fish were so big that you couldn't put any of those small fish up on it".

The video was recorded on the Mission Blue Voyage on the National Geographic Endeavor, the Galápagos Islands, Ecuador.

TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts.
