Study Notes
Land Pollution
- Land pollution is the deterioration of the earth's surface, both at and below ground level, caused by accumulated solid and liquid waste.
- This waste contaminates groundwater and soil.
- Municipal solid waste (MSW) includes hazardous and non-hazardous materials.
- Pollutants like heavy metals, pesticides, plastics, litter, and pharmaceuticals damage soil composition.
- Pollutants can transform into secondary pollutants.
- Soil permeability affects the risk of land pollution.
- Extreme weather (hurricanes, floods) can spread or concentrate pollutants.
Main Causes of Land Pollution
- Litter (improper disposal of waste) is a major cause.
- Cleanup costs for litter in the US are estimated at over $11.5 billion annually.
- U.S. roadways and waterways contain an estimated 50 billion pieces of litter.
- Illegal dumping (waste in unauthorized locations) is another major contributor.
- Dumped waste includes asbestos, cars, and recyclable materials.
- Urbanization and construction produce large amounts of waste.
- Mining and extraction damage the environment and produce waste.
- Acid mine drainage is used in coal mining and pollutes waterways.
- Agriculture (pesticides, fertilizers, animal waste) contributes greatly to land pollution.
- Unsustainable farming practices strip the land of nutrients.
Effects of Land Pollution
- Contaminated drinking water sources.
- Loss of fertile land for agriculture reducing food supplies.
- Climate change (increased floods and other natural disasters)
- Threatening wildlife habitats and increasing endangerment.
- Reduced biodiversity and habitat shifting.
- Increased wildfires.
- Air pollution.
- Soil pollution causing health issues in humans and animals.
Preventing Land Pollution
- Sustainable agricultural practices (alternative farming practices, local farmers' markets, support sustainable farms) can reduce farm waste.
- Reforestation (replanting trees) supports soil stability and reduces land erosion.
- Solid waste treatment (methods like neutralization) helps to reduce toxic chemical levels.
Reduce, Reuse, Recycle
- Reducing waste creation and reuse of items are important actions to limit land pollution.
- Composting is another method to reduce land pollution.
- Food scraps and yard waste make up a large percentage of waste.
- Composting is a way to repurpose these materials.
