Catch: Then, Now

Caption

The gray line represents the average trophic level of what was caught worldwide starting in 1950 according to a 1998 Science paper about fishing down the marine food web. Newly revised and updated information, the black line, shows that the average trophic level of what is being caught has, instead, been generally going up since the mid 1980s.
