What is a significant characteristic of methane produced in landfills?

Methane produced in landfills is a potent greenhouse gas, which makes its contribution to global warming and climate change significant. When organic waste decomposes in landfills, it does so anaerobically, meaning without oxygen, leading to the production of methane as a byproduct. This gas is much more effective than carbon dioxide at trapping heat in the atmosphere, making it a critical concern from an environmental perspective.

The characteristic distinction of methane as a greenhouse gas highlights the challenges associated with waste management and the need for effective landfill gas capture and management systems to mitigate its impact. Methane's contribution to greenhouse gases is not only important for understanding climate dynamics but also informs strategies for waste reduction and pollution control in public health and environmental sanitation practices.
