Fish are shrinking around the world. The average body weight of nearly three-quarters of marine fish populations sampled dropped between 1960 and 2020, a recent study suggests.

no one can agree why

I think most people can agree it’s a combination of pollution, overfishing and climate change. Probably just unclear which one of those factors in the most.

Crazy idea, but what about fishing-driven evolutionary pressure. If all the biggest fish are getting caught and killed, won’t that give smaller fish an evolutionary advantage?
