  1. Climate change

  2. Pollution

  3. Overfishing

  4. Habitat loss
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Multiple choice

How does desertification lead to migration?

  1. Loss of agricultural productivity forces people to migrate in search of food

  2. Loss of biodiversity reduces the availability of resources for people to use

  3. Increased poverty makes it difficult for people to stay in their homes

  4. All of the above

  5. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Desertification leads to migration because it causes loss of agricultural productivity, loss of biodiversity, and increased poverty. These factors make it difficult for people to stay in their homes, and they are forced to migrate in search of better opportunities.
