What are the main threats to coral reefs?

  1. Climate change

  2. Overfishing

  3. Pollution

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Climate change, overfishing, and pollution are all major threats to coral reefs. Climate change is causing the ocean to become warmer and more acidic, which is harmful to coral. Overfishing can reduce the number of fish that graze on algae, which can lead to an overgrowth of algae that can smother coral. Pollution can also harm coral by introducing toxins into the water.
