2. Which of the following best explains how clearcutting contributes to climate change on a global scale?

• (A) Clearcutting requires prescribed burning or setting controlled forest fires to reduce the occurrence of natural fires.
• (B) Clearcutting results in a loss of biodiversity and adds to the problems of endangered species and extinctions.
