  Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles.

  There’s also 1.5 billion cows in the world that scientists think can produce as much methane (a greenhouse gas) as an average car in a day!
