Multiple choice

Which of the following is a threat to mangrove forests?

  1. Deforestation

  2. Pollution

  3. Climate change

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

Mangrove forests are threatened by a number of human activities, including deforestation, pollution, and climate change.
