The latest research shows that humans are the leading cause of wildfires in the United States. As global warming leads to longer fire seasons and larger wildfires, human activity is causing wildfires to happen at times of the year when they would not be happening naturally.

Listen to learn more about humans’ role in increasing wildfires, and what ecologists believe must be done to reverse this trend.
