Our overwhelming societal depression issues are causing increases in antidepressants in the ocean which are causing shrimp to swim up to higher waters (closer to sunlight), making them more likely to get eaten by predators! So because we live in a world that forces us to be unhappy all the time where the only escape is constant medication, they are getting drugged into a blissful "find the light" kind of state where they end up dying. It's kind of sad, if you think about it. Or ironic? Probably not ironic. Probably just sad. Or unexpected, anyways.
I wonder what other sea life is blissing out to our meds?
