Multiple choice

What is the primary cause of biodiversity loss?

  1. Habitat loss.

  2. Pollution.

  3. Climate change.

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

Habitat loss, pollution, and climate change are all major causes of biodiversity loss. Habitat loss occurs when natural habitats are converted to other uses, such as agriculture or development. Pollution can contaminate habitats and make them uninhabitable for wildlife. Climate change can alter habitats and make them unsuitable for certain species.
