Wildfire is a natural process that takes place in forests and grasslands all over the world. In dry conditions, a single spark can rapidly transform into flames that stretch for miles and sweep across the landscape, burning away everything in their path. Although commonly seen as destructive and deadly, fire is a necessary part of ecosystems; they refresh the land and allow for new plant growth. Environmental scientist Ferin Davis Anderson and author Stephanie Sammartino McPherson examine how Indigenous people, farmers, and forestry departments have used fire to manage resources; why climate change is impacting the frequency and intensity of wildfires; and what the future of fire might look like.
