Causes of global worming

Do you believe that we are the main reason behind global worming? There are many causes of global warming and these are same of them. First, carbon dioxide emissions that stem from the burning of fossil fuels for the purpose of electricity generation, second, carbon dioxide emissions comes from the burning of gasoline in engines of cars and light trucks minivans, sport utility vehicles and pick-up trucks. Third, Methane is more than 20 times as effective as CO2 at trapping heat in the atmosphere which is derived from sources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel production. Last but no least is City gridlock, by cars starting and stopping to move few meters is not a way to improve the environment and it was found that drivers in Los Angeles and New York City alone wasted 600 million gallons of gas annually while just sitting in traffic.
