Ocean acidification is a significant environmental issue that affects marine ecosystems around the world. It occurs when carbon dioxide (CO2) is absorbed by the ocean, leading to a decrease in pH levels. This process can have detrimental effects on various marine organisms, including corals, shellfish, and plankton.
Key Points
- CO2 Emissions: The primary cause of ocean acidification is the increase in CO2 emissions from human activities such as burning fossil fuels.
- pH Levels: The pH of the ocean has decreased by 0.1 since the beginning of the Industrial Revolution, making it more acidic.
- Impacts on Marine Life: Ocean acidification can hinder the growth and development of marine organisms, leading to a decline in biodiversity.
Impacts on Marine Organisms
- Coral Reefs: Corals are particularly vulnerable to ocean acidification. They rely on calcium carbonate to build their skeletons, and the increased acidity can dissolve these structures.
- Shellfish: Shellfish, such as oysters and clams, also face challenges due to ocean acidification. The increased acidity can make it difficult for them to produce and maintain their shells.
- Plankton: Plankton forms the base of the marine food web. Ocean acidification can impact plankton populations, which can have cascading effects on the entire ecosystem.
