What factors contribute to the urgent need for intervention in coral reef ecosystems?

• A. Increased recreational diving activities
• B. Decline in coral species diversity
• C. Climate change and pollution
• D. Government regulations on fishing

Answer: (C)

The urgent need for intervention in coral reef ecosystems is primarily driven by climate change and pollution. Climate change leads to elevated water temperatures, which can cause coral bleaching, a process where corals lose their symbiotic algae and, in turn, their color and food source. This makes them vulnerable to disease and mortality. Additionally, increased levels of carbon dioxide in the atmosphere result in ocean acidification, which adversely affects the ability of corals to build their calcium carbonate structures. Pollution further exacerbates the situation by introducing harmful substances such as nutrients, sediments, and plastics into marine environments. These pollutants can lead to harmful algal blooms, disrupt the delicate balance of reef ecosystems, and negatively impact the health of the corals themselves and the myriad of species that depend on them. While increased recreational diving activities and government regulations on fishing may play roles in the sustainability and health of coral reefs, they do not represent the systemic threats posed by climate change and pollution. Likewise, a decline in coral species diversity can be a consequence of these overarching issues rather than a direct cause that necessitates intervention. Addressing climate change and pollution is therefore critical for the long-term preservation of coral reef ecosystems.
