Definition
Ocean acidification refers to the process by which the pH of ocean water decreases due to the absorption of excess atmospheric carbon dioxide, leading to increased acidity. This phenomenon can adversely affect marine organisms, particularly those with calcium carbonate structures, such as corals and shellfish.
Summary
Ocean acidification is a significant environmental issue caused by the absorption of excess carbon dioxide from the atmosphere into the oceans. This process lowers the pH of seawater, making it more acidic, which can have detrimental effects on marine life, particularly organisms that rely on calcium carbonate for their shells and skeletons, such as corals and shellfish. As the ocean becomes more acidic, it disrupts the delicate balance of marine ecosystems, leading to potential declines in biodiversity and changes in food webs. The implications of ocean acidification extend beyond marine life; they also affect human activities, particularly fisheries and tourism, which are vital for many coastal communities. Mitigation strategies, such as reducing carbon emissions and protecting marine habitats, are essential to combat this issue. Understanding ocean acidification is crucial for developing effective policies and practices to safeguard marine ecosystems and the livelihoods that depend on them.
Key Takeaways
Ocean pH is Decreasing
The ocean's pH has dropped by about 0.1 units since the Industrial Revolution, indicating increased acidity.
highImpact on Marine Life
Many marine organisms, especially corals and shellfish, struggle to survive in more acidic waters.
highHuman Economic Impact
Ocean acidification can affect fisheries and tourism, leading to economic challenges for coastal communities.
mediumMitigation is Possible
Reducing carbon emissions and protecting marine habitats can help mitigate the effects of ocean acidification.
