56. Paragraph F

Another strategy is to burn as much methane as possible. This adds CO2 to the air, but since methane traps

twenty times as much heat as CO2 the net result is worthwhile. The gas in many garbage landfills is already

being used in a number of places around the United States. It is being used to heat thousands of homes.
