The Dust Bowl · US History

How did the Dust Bowl affect the biodiversity of the Great Plains?

  1. It led to a massive increase in the population of bison
  2. It forced nearly all surviving animals in the region to permanently migrate north to Canada
  3. It caused massive die-offs of livestock and native wildlife due to lack of food and water
  4. It had no effect on animal life because they lived underground
Show answer and explanation

Correct answer: It caused massive die-offs of livestock and native wildlife due to lack of food and water

The ecological collapse affected the entire food chain. Birds, rabbits, and cattle died from starvation or 'dust fever,' and the loss of vegetation destroyed the habitats that supported the region's wildlife.
