First, 90 percent of all wildfires are started by humans, whether from arson, careless behavior, or lack of fire safety. Weather factors, such as lightning and drought conditions, also contribute to wildfires. According to National Geographic, more than 100,000 wildfires clear between four and five million acres of land in the U.S. each year – sometimes up to nine million acres in a single year.
