Question

An environmental problem caused by landfills are

• A. Methane production
• B. Groundwater pollution
• C. Incomplete decomposition
• D. All of the above

Answer 1

The correct option is D

All of the above

The environmental problems caused by landfills are numerous. The methane produced by the rotting organic matter in unmanaged landfills is 20 times more effective than carbon dioxide at trapping heat from the sun. Landfills also create a toxic soup of industrial and home-cleaning chemicals. These chemicals accumulate and are washed away periodically by rain, potentially dragging them toward municipal water supplies and contaminating ground water .Incomplete decomposition in a land fill releases foul gases which is one of the causes of air pollution too.
