Summary: The text discusses the impact of ocean acidification on marine ecosystems and organisms, highlighting the challenges and potential consequences associated with this phenomenon. Ocean acidification is caused by the absorption of excess carbon dioxide from the atmosphere, leading to a decrease in pH levels in seawater. This process can have detrimental effects on calcifying organisms such as corals, shellfish, and plankton, as it hinders their ability to build and maintain their calcium carbonate shells and structures. The increasing acidity of the ocean also poses a threat to marine food webs and biodiversity, as it can disrupt the balance of marine ecosystems and alter the physiology of various species. Researchers are studying the effects of ocean acidification on marine life, with a focus on finding solutions to mitigate its impact and protect vulnerable species and habitats in the face of ongoing climate change.
