If There Were A Decrease In The PH (increase In Acidity) Of The Ocean, What Would Happen To Growing Corals? What Would Happen To The Reef Overall?
The Impact of Ocean Acidification on Coral Reefs: A Threat to Marine Biodiversity
Introduction
The world's oceans play a vital role in regulating the Earth's climate, providing a source of food for millions of people, and supporting a vast array of marine life. However, the oceans are facing a significant threat in the form of ocean acidification, which is caused by an increase in the concentration of carbon dioxide (CO2) in the atmosphere. This increase in CO2 leads to a decrease in the pH of the ocean, making it more acidic. In this article, we will explore the impact of ocean acidification on growing corals and the overall health of coral reefs.
What is Ocean Acidification?
Ocean acidification is the decrease in the pH of the ocean due to the absorption of CO2 from the atmosphere. This process is known as the ocean's "carbon sink." The ocean absorbs approximately 25% of the CO2 released into the atmosphere, which reacts with water to form carbonic acid. This reaction reduces the pH of the ocean, making it more acidic.
The Impact of Ocean Acidification on Coral Reefs
Coral reefs are one of the most diverse and complex ecosystems on the planet, supporting a vast array of marine life. However, coral reefs are highly sensitive to changes in the ocean's chemistry, particularly the pH. When the pH of the ocean decreases, it becomes more difficult for corals to build their skeletons, which are made of calcium carbonate. This is because the decrease in pH reduces the availability of carbonate ions, which are necessary for coral growth.
The Effects of Ocean Acidification on Coral Growth
Studies have shown that corals are able to grow and thrive in a pH range of 8.1 to 8.3. However, when the pH of the ocean decreases to 7.9 or lower, coral growth is significantly impaired. This is because the decrease in pH reduces the availability of carbonate ions, making it more difficult for corals to build their skeletons.
- Reduced Coral Growth: Ocean acidification can lead to reduced coral growth, making it more difficult for corals to build their skeletons and maintain their structure.
- Increased Coral Mortality: The decrease in pH can also lead to increased coral mortality, as corals are more susceptible to disease and stress.
- Changes in Coral Community Composition: Ocean acidification can lead to changes in the composition of coral communities, as some species are more resilient to the decrease in pH than others.
The Impact of Ocean Acidification on the Reef Overall
The impact of ocean acidification on coral reefs is not limited to the corals themselves. The decrease in pH can also have a significant impact on the overall health of the reef.
- Reduced Biodiversity: Ocean acidification can lead to reduced biodiversity on coral reefs, as some species are more resilient to the decrease in pH than others.
- Changes in Food Webs: The decrease in pH can also lead to changes in food webs, as some species are more susceptible to the decrease in pH than others.
- Economic Impacts: The impact of ocean acidification on coral reefs can also have significant economic impacts, particularly in areas where coral reefs are a major source of income.
Conclusion
Ocean acidification is a significant threat to coral reefs, and the impact of this process on growing corals and the overall health of the reef is well-documented. The decrease in pH makes it more difficult for corals to build their skeletons, leading to reduced coral growth and increased coral mortality. The impact of ocean acidification on the reef overall is also significant, leading to reduced biodiversity, changes in food webs, and economic impacts. It is essential that we take action to reduce the amount of CO2 released into the atmosphere and mitigate the effects of ocean acidification on coral reefs.

Frequently Asked Questions: Ocean Acidification and Coral Reefs
Q: What is ocean acidification, and how does it affect coral reefs?
A: Ocean acidification is the decrease in the pH of the ocean due to the absorption of CO2 from the atmosphere. This process makes it more difficult for corals to build their skeletons, leading to reduced coral growth and increased coral mortality.
Q: How does ocean acidification affect coral growth?
A: Ocean acidification can lead to reduced coral growth, making it more difficult for corals to build their skeletons and maintain their structure. This is because the decrease in pH reduces the availability of carbonate ions, which are necessary for coral growth.
Q: What are the economic impacts of ocean acidification on coral reefs?
A: The impact of ocean acidification on coral reefs can have significant economic impacts, particularly in areas where coral reefs are a major source of income. This can include reduced tourism revenue, decreased fishing yields, and loss of livelihoods.
Q: How can we mitigate the effects of ocean acidification on coral reefs?
