Climate change is damaging fish brains and causing them to lose their survival instinct, researchers warn.

Carbon dioxide released into the atmosphere is absorbed into ocean waters, where it dissolves and lowers the pH of the water. Fishes sensory systems were impaired by the change, causing neurons in the brain to misfire and they were unble to distinguish predators.

‘These results verify our laboratory findings,’ said Danielle Dixson, an assistant professor in the School of Biology at the Georgia Institute of Technology in Atlanta.
