Dolphins Are Forgetting
They remember us — but now, they are beginning to forget.
In waters clouded by our waste, dolphins—once symbols of memory and intelligence—are showing signs of something heartbreakingly human. Scientists have found amyloid plaques, tau tangles, and brain shrinkage in stranded bottlenose, Risso’s, and striped dolphins: the same hallmarks seen in Alzheimer’s disease.
The culprits drift unseen — BMAA toxins from algal blooms, mercury, PCBs, and a century’s worth of pollution dissolving into the sea. Each breath a dolphin takes carries traces of us — our chemicals, our carelessness, our memory loss made visible in another species.
Dolphins are the sentinels of the ocean, mirrors of its health and ours. And as their memories fade, they warn us that what poisons them may already be shaping our own fate.
When the ocean begins to forget, it doesn’t forget alone.
