  4. Tourism
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Climate change, particularly rising sea temperatures, is the primary cause of habitat destruction in coral reefs, leading to coral bleaching and death.

Multiple choice

Which factor contributes to habitat destruction in wetlands?

  1. Dams and Levees

  2. Invasive Species

  3. Water Pollution

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

Habitat destruction in wetlands can be caused by dams and levees altering water flow, invasive species outcompeting native species, and water pollution degrading the ecosystem.

Multiple choice

The Tragedy of the Commons is primarily concerned with:

  1. The overuse of renewable resources.

  2. The overuse of non-renewable resources.

  3. The overuse of both renewable and non-renewable resources.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
