Fish are losing their sense of smell because of increasingly acidic oceans caused by rising levels of carbon dioxide (CO2) in the atmosphere, new research shows.
When carbon dioxide is absorbed by seawater carbonic acid is formed, making the water more acidic. Since the Industrial Revolution, oceanic CO2 has risen by 43% and is predicted to be two and a half times current levels by the end of this century.
Fish use their sense of smell (olfaction) to find food, safe habitats, avoid predators, recognize each other and find suitable spawning grounds…
