Ocean absorbs approximately 30% of human-made CO2 changing the chemistry of seawater to become more acidic. This first affects marine life like coral and plankton being able to form shells and skeletons and ends with some groups of small fish with a loss of habitat and food supply. It results in the less life span of the numerous organisms as well as marine life is also very badly affected by it. Acidic water is dangerous for the living organisms as fishes and many other marine organisms can’t survive in very acidic water.
