FAQs on Ocean Acidification Video Lecture - Environment for UPSC CSE
| 1. What is ocean acidification? |  |
Ans. Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the absorption of carbon dioxide (CO2) from the atmosphere. This process leads to increased acidity in the water, which can have detrimental effects on marine life and ecosystems.
| 2. How does ocean acidification occur? | |
Ans. Ocean acidification occurs when carbon dioxide is absorbed by seawater, which then reacts with water molecules to form carbonic acid. This acidification process reduces the concentration of carbonate ions in the water, making it more difficult for marine organisms like corals, shellfish, and plankton to build their shells and skeletons.
| 3. What are the main consequences of ocean acidification? | |
Ans. The main consequences of ocean acidification include the potential disruption of marine food webs, as many species rely on shell-building organisms for their survival. It can also lead to coral bleaching and the degradation of coral reefs, which are important habitats for countless marine species. Additionally, ocean acidification can affect the behavior and reproduction of certain fish species, ultimately impacting the entire marine ecosystem.
| 4. How does ocean acidification relate to climate change? | |
Ans. Ocean acidification is closely linked to climate change, as both processes are driven by the increase in atmospheric carbon dioxide concentrations. The same human activities that contribute to the release of greenhouse gases, such as burning fossil fuels and deforestation, also result in higher levels of carbon dioxide in the atmosphere. This excess CO2 is then absorbed by the oceans, leading to acidification.
| 5. Can anything be done to mitigate ocean acidification? | |
Ans. While it may not be possible to completely reverse ocean acidification, reducing carbon dioxide emissions can help slow down the process. Implementing climate change mitigation strategies, such as transitioning to renewable energy sources and promoting sustainable land use practices, can help reduce the amount of CO2 released into the atmosphere. Additionally, protecting and conserving marine ecosystems can help enhance their resilience to ocean acidification.
