What is mentioned as a driver of coral bleaching events worldwide?
A) Decreasing sea temperatures
B) Increasing ocean acidity
C) Reduced levels of pollution
D) Preservation of coral habitats


Sagot :

Final answer:

Ocean acidification and warming temperatures, driven by climate change, are major factors causing coral bleaching events globally.


Explanation:

Coral Bleaching and Its Drivers

Ocean acidification, primarily caused by increased atmospheric CO₂ levels, along with warmer temperatures, contributes to coral bleaching events worldwide. The process involves corals expelling algae crucial for photosynthesis due to stressors like temperature changes and high acidity.

  • Climate change impacts coral reefs through ocean acidification and elevated temperatures, leading to ecosystem destruction.
  • Corals' sensitivity to changes in ocean pH makes them susceptible to bleaching events triggered by global warming and anthropogenic influences.
  • Continued habitat changes due to ocean acidification pose a significant threat to coral reefs' survival, highlighting the urgency of addressing climate change impacts.
