http://en.wikipedia.org/wiki/Landfill#Problems
Advantage:
1. Efficient waste management: Landfills provide a centralized location for waste disposal, allowing for efficient collection and containment of solid waste. They offer a convenient option for communities to manage and dispose of their waste while ensuring public health and environmental safety to an extent.
Disadvantage:
1. Environmental impact: One major disadvantage of landfills is their negative impact on the environment. As waste decomposes, it releases harmful greenhouse gases, such as methane, contributing to climate change. Landfills can pollute nearby soil and groundwater with leachate, a liquid that forms as waste decomposes, potentially contaminating local ecosystems if not managed properly.
