ANS: B
Solid waste landfills accumulate methane gas, a by-product of decomposing organic wastes. Without proper venting, this volatile gas can move through soil and cause fires and explosions in nearby areas. Waste incineration is not the best solution because it causes particulate air pollution. Illegal dumping of garbage and purchasing additional land for more landfills are concerns related to the disposal of trash from private residents, but methane gas explosions is of primary concern.
