Landfills are a common method of waste management, but they can have a detrimental impact on the environment and human health. Landfills contribute to land pollution, which is the degradation of the Earth's land surfaces and groundwater by outside contaminants.
Landfills are often the final destination for our trash, even after recycling. When not managed properly, landfills can contaminate the soil and water with hazardous materials, heavy metals, and chemicals. This is known as leachate and can be toxic to humans and animals, causing various health issues. The creation of landfills also often means destroying natural habitats for wildlife, and the gases emitted from landfills contribute to climate change and air pollution.
While landfills are a necessary part of waste management, there are ways to reduce their impact, such as recycling, avoiding single-use plastics, and composting.
| Characteristics | Values |
|---|---|
| Climate change | Landfills are one of the causes of climate change as they generate and release biogas into the atmosphere. Biogas is a mixture of methane gas and carbon dioxide, two of the gases that cause climate change and an increase in the planet's temperature. |
| Explosions and fires | Sometimes methane produced by waste from landfill sites can cause explosions and fires. |
| Contamination of soil and water | Landfill sites are often responsible for the contamination of soil and groundwater, as the contaminating materials (such as heavy materials like lead and mercury) that the stored waste may contain can spread to the soil and water near the plant. |
| Alteration of fauna | Landfill sites have particularly negative effects on bird migration. Some birds feed from landfill sites, inevitably ingesting plastic, aluminium, gypsum and other materials that are common among waste, which can even prove fatal. |
| Reduction in property value | The bad smells that emanate from landfill sites reach nearby populations. Property prices are reduced in areas located near to these waste stores, which further perpetuates the devaluation of disadvantaged areas. |
| Accidents | In March 2017, the Addis Ababa landfill site in Ethiopia collapsed, causing an estimated 113 deaths. Only a month later, the Meethotamulla landfill site in Sri Lanka suffered a landslide, leaving more than 30 people dead. |
What You'll Learn
Landfills contribute to climate change
Moreover, organic material sent to landfills is expected to increase, leading to higher emissions of greenhouse gases. In addition, landfills can cause air pollution through the suspension of particles and the release of odors from decomposing waste. The decomposition process also results in the release of carbon dioxide and carbon monoxide, further contributing to climate change.
Another way landfills contribute to climate change is by altering the fauna. Landfills negatively impact bird migration, as some birds feed on the waste, ingesting harmful substances such as plastic and aluminum. Additionally, landfills can change migratory behavior, with some species choosing to nest near landfill sites due to the abundant food supply. This disruption in bird migration can have cascading effects on ecosystems.
Furthermore, landfills contribute to climate change through their impact on water systems. The leaching of organic and inorganic substances from landfills can contaminate groundwater and surface water sources, affecting both human and aquatic life. The release of toxic chemicals and heavy metals into water bodies can have far-reaching consequences for the environment and human health.
Lastly, landfills are often associated with uncontrolled fires and explosions due to the accumulation of methane gas. These fires release dioxin emissions, which are extremely harmful to the environment and can have long-lasting effects on aquifers and water systems. Overall, landfills play a significant role in contributing to climate change, and mitigating their impact is crucial for a sustainable future.

They contaminate soil and water
Landfills contaminate soil and water through the release of harmful chemicals and toxins.
Landfills are often responsible for the contamination of soil and groundwater. This is due to the presence of hazardous materials in the waste, which can spread to the surrounding soil and water. These contaminants include heavy metals such as lead and mercury, as well as other toxins such as ammonia, nitrate, and mercury.
The creation of landfills often involves the destruction of natural habitats for wildlife, with the average landfill size being 600 acres. This results in a loss of biodiversity and can alter migratory patterns, as some species are drawn to the endless food supply provided by landfills.
While landfills are required to have plastic or clay liners to prevent leakage, these liners often have leaks, resulting in the contamination of nearby water sources. This further damages ecosystems and poses risks to human health. Leachate, a liquid produced by landfill sites, can contain high levels of ammonia, which can cause eutrophication in nearby water sources, creating "dead zones" where animals cannot survive due to a lack of oxygen.
The impact of landfill contamination extends beyond the immediate environment, affecting human health and well-being. Emissions from landfills, including methane and other gases, pose health risks to those living and working nearby. Studies have found increased rates of respiratory issues, congenital malformations, and other health problems in populations close to landfill sites.
To mitigate the impact of landfills on soil and water contamination, proper waste management practices, such as recycling and composting, are essential. These practices can reduce the amount of waste sent to landfills, minimizing the release of harmful contaminants.

They alter fauna
Landfills alter fauna in a variety of ways. Firstly, they can disrupt bird migration patterns, as some species opt to nest near landfill sites due to the abundance of food available. This can prove fatal for birds, as they inevitably ingest plastic, aluminium, gypsum, and other materials commonly found in landfills.

They reduce the value of surrounding areas
Landfills can reduce the value of the surrounding areas in several ways. Firstly, the foul odours that emanate from landfill sites can reach nearby populations, causing a nuisance and negatively impacting the quality of life for residents. These unpleasant smells are difficult to control and can lead to a decrease in property prices in the surrounding areas. This further perpetuates the devaluation of disadvantaged areas.
In addition, the presence of a landfill can affect the natural habitats of wildlife, leading to a loss of biodiversity. The average landfill size is 600 acres, and with over 3,000 active landfills in the United States alone, a significant amount of wildlife habitat has been lost. This disruption to ecosystems can have far-reaching consequences, including the displacement of animal species and a negative impact on migration patterns.
The visual impact of landfills can also contribute to the reduction in land value. Large landfills are unsightly and can detract from the aesthetic appeal of an area. This can make the surrounding areas less desirable for potential residents or businesses, leading to a decrease in property values and a potential decline in economic activity.
Furthermore, the potential health risks associated with living near a landfill can also influence the value of surrounding areas. Studies have shown that emissions from landfills can pose health hazards, with increased risks of respiratory issues, congenital malformations, and certain types of cancer. The presence of these health risks may deter people from wanting to live or invest in properties close to landfill sites, thereby reducing the desirability and value of the surrounding areas.
