Ocean acidification causes a decrease in the pH concentration of the oceans, mostly arises as a result of the entry of carbon dioxide from the atmosphere.
A fisherman noticing a shellfish's shell being very small and lack the thick hard shell may be due to Ocean acidification (option A).
- Ocean acidification is mainly caused by fossil fuels and leads to a decrease in the water's pH.
