Multiple choice

What are the primary consequences of deforestation?

  1. Loss of biodiversity

  2. Climate change

  3. Soil erosion

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

Deforestation leads to the loss of biodiversity, as many species rely on forests for their survival. It also contributes to climate change by releasing carbon dioxide into the atmosphere and reducing the Earth's ability to absorb carbon dioxide.
