When trash accumulates and begins to break down, carbon dioxide and methane are produced. These gases can be taken out, filtered out, and used for energy production. In the United States, landfills serve as the third source of methane production.
How do landfills benefit the environment?

The most potent of these, perhaps, is leachate, which can contaminate underground water sources. … In short, they are not a sustainable form of waste management, as future generations will have to address the landfill problem that we are creating today.

How do landfills affect humans?
Previous research shows that people living closer to landfill sites suffer from medical conditions such as asthma, cuts, diarrhoea, stomach pain, reoccurring flu, cholera, malaria, cough, skin irritation, cholera, diarrhoea and tuberculosis more than the people living far away from landfill sites [31,32,33,34,35,36].
How do landfills contribute to global warming?
Soil is needed to cover fresh waste every day, and once the landfill has reached its capacity, the waste is covered with more clay and another plastic sheet. Since this waste is simply “stored” as opposed to broken down, it releases methane gas, the greenhouse gas that contributes to climate change.
How do landfills affect the environment?
Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.
