The devastation caused by wildfires makes headlines every year and continues to worsen. Wildfires cause not only enormous humanitarian and economic hardship but also have a massive environmental impact. In addition to destroying animal and plant life, wildfires emit between 5 and 30 tons of carbon per hectare. All of the land that burns globally in an average year adds 13 billion metric tons of additional carbon to the atmosphere annually, a significant contribution to climate change.
