Multiple choice

What is the primary cause of human-wildlife conflict?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Overpopulation

  4. Pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Habitat loss and fragmentation are the primary causes of human-wildlife conflict as they reduce the availability of resources for wildlife, forcing them to come into contact with humans more frequently.

Multiple choice

Which of the following is NOT a consequence of human-wildlife conflict?

  1. Loss of biodiversity

  2. Economic losses

  3. Increased risk of disease transmission

  4. Improved human-wildlife coexistence
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Improved human-wildlife coexistence is not a consequence of human-wildlife conflict. It is a goal that can be achieved through effective conflict mitigation strategies.

Multiple choice

Which of the following is NOT a factor that contributes to retaliatory killing?

  1. Loss of livestock

  2. Crop damage

  3. Fear of predators

  4. Cultural beliefs
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cultural beliefs are not a factor that contributes to retaliatory killing. Retaliatory killing is primarily driven by economic losses and fear of predators.

Multiple choice

What are some of the negative consequences of retaliatory killing?

  1. Increased human-wildlife conflict

  2. Loss of biodiversity

  3. Economic losses

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

Retaliatory killing can lead to increased human-wildlife conflict, loss of biodiversity, and economic losses.

Multiple choice
