How do brush fires affect the environment?
Brush fires start an endless cycle where they are adding to climate change and its effects. According to the NOAA and the Greenhouse Gas Reference Network, a large fire that destroys 500,000 acres has the potential to emit the same amount of CO2 as six large coal-fired power plants in one year.
What happened to Southern California’s wildfires?
