Question

A fisherman collecting shellfish notices that many are very small and lack the thick hard shell he is accustomed to seeing in the species. Which statement best explains what may be impacting the shellfish population?
- Ocean acidification
- Ocean warming
- Coral bleaching
- Climate change

Answer 1

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.
• It also causes a reduction in the amount of carbonate, a building block of shells and skeletons in seawater.
• This makes it very difficult for marine organisms, such as shell fish and corals, to form their shells and skeletons, and those with existing shells may begin to dissolve.
