As a teenage fisherman, I watched and followed terns to find fish. Later, I studied terns for my Ph.D.

From the happy-go-lucky days of oil exploration and drilling, when a lot of easy sources were being found and easily managed, we're gotten ourselves into this sort of apocalyptic time. We're willing to destroy almost everything, risk almost anything, and go ahead with techniques for which we have no way of responding to the known problems.

Several groups have information evaluating seafood sustainability. I wrote the first such guide, and seafood pocket-guides and detailed evaluations of different seafoods are available for download from the group I founded, Blue Ocean Institute.

When I was in high school in the early 1970s, we knew we were running out of oil; we knew that easy sources were being capped; we knew that diversifying would be much better; we knew that there were terrible dictators and horrible governments that we were enriching who hated us. We knew all that and we did really nothing.
