We all know that burning fossil fuels is fueling climate change, which is making extreme weather events like heat waves, wildfires, hurricanes, floods and droughts more frequent and more severe. But did you know that air pollution from fossil fuel combustion is also cutting the lifespan of the average person by up to 2.3 years? That's according to the latest Air Quality Life Index from the Energy Policy Institute at the University of Chicago, which found that burning fossil fuels is reducing life expectancy globally more than major causes of death like alcohol use, unsafe water, car crashes or HIV/AIDS. Sign the petition urging world leaders to stop burning fossil fuels and instead invest in clean, renewable sources of energy like solar and wind.
