  4. List of Greenhouse Gases • Water Vapor- -most powerful • Carbon dioxide- -burning fossil fuels • Methane- -produced by decay of organic material in landfills, enteric fermentation in the digestive tracts of hooved animals such as cattle, goats, and sheep (feces) • Nitrous Oxide- -produced by fertilizer use
