Landfills have a tendency to emit a host of toxic gases into the air, and by toxic gases we actually mean cytotoxic or carcinogenic gases, like benzene and vinyl chloride. They also leak into the surrounding soils and water sources.
Furthermore, landfills produce methane -- rather, microbes produce it as they devour anything they can and emit methane as a waste product. Being lighter than air, methane works its way out of the air and into the soils or the atmosphere. Methane has a very high global warming potential (GWP), about 12 times as high as carbon dioxide.
