Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Overpopulation is not typically considered a direct threat to wildlife and natural habitats, although it can indirectly contribute to habitat loss and resource depletion.

Multiple choice

Which of the following is an example of a habitat that is threatened by climate change?

  1. Coral reefs

  2. Rainforests

  3. Arctic sea ice

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

Coral reefs, rainforests, and Arctic sea ice are all habitats that are threatened by climate change. Coral reefs are threatened by rising sea temperatures, which can cause coral bleaching and death. Rainforests are threatened by deforestation and climate change, which can lead to changes in precipitation patterns and increased temperatures. Arctic sea ice is threatened by rising temperatures, which is causing the ice to melt.

Multiple choice

What are some examples of the Tragedy of the Commons?

  1. The overgrazing of common pastures.

  2. The overfishing of fisheries.

  3. The pollution of the environment.

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

The Tragedy of the Commons can be seen in a variety of situations, including the overgrazing of common pastures, the overfishing of fisheries, and the pollution of the environment. In each of these cases, multiple individuals, acting independently and rationally according to their own self-interest, are depleting a shared resource even when it is in their collective interest to conserve it.
