fish.

“Everything in the ocean depends on them,” explained Ellen Pikitch, the executive director of the Institute for Ocean Conservation Science at Stony Brook University. Specifically, underwater ecosystems rely heavily on “forage fish,” which include sardines, anchovies, herring, and more. But according to a report released by Pikitch’s solemnly named Forage Fish Task Force, many of these species are dying out. This is because they’re sensitive to changes in the environment and over-pursued by fishermen, who can easily scoop up densely packed schools.

Salmon, penguins, whales, and many kinds of birds depend on these species as prey, and when the tiny creatures die out, so do their predators.
