• The increasing acidity in ocean waters can significantly impact the living organisms within it.
• The ocean water on earth had a pH of 8.2. which has dropped to 8.1 in recent years.
• This transition could influence the ocean ecosystem in a way that the coral skeletons may become fragile due to increased acidity.
