Study Notes

Land Pollution

Land pollution is the deterioration of Earth’s land features and soil, caused by human activities and the misuse of land resources.
It often leads to undesirable changes in land, like soil erosion.
Land pollution lessens the quality and/or productivity of the land for agriculture, forestation, and other uses.

Causes of Land Pollution

Deforestation and Soil Erosion: Converting land to dry or barren land can make it permanently infertile.
Agricultural Activities: Overuse of toxic fertilizers and pesticides contaminate and poison soil.
Mining Activities: Extraction and mining activities leave spaces beneath the surface, which can lead to land caving in.
Overcrowded Landfills: Garbage that cannot be recycled fills landfills, harming the environment and the city's aesthetics.
Industrialization: Increased demand for goods leads to more waste and deforestation, and industrial development contributes to soil contamination.
Urbanization: Significant changes to the landscape can cause land pollution in various subtle and not-so-subtle ways.
Construction Activities: Large quantities of waste materials from construction activities pollute the environment.
Nuclear Waste: Leftover radioactive material contains toxic chemicals that can harm human health and are often dumped underground to avoid casualties.
Sewage Treatment: Treated sewage still produces solid waste, which is often sent to landfills and can pollute the environment.
Littering: Throwing garbage on the ground without consideration for the environment.

Disastrous Effects of Land Pollution

Groundwater Poisoning
Drinking Water Problems
Climate Change
Human Health Problems
Air Pollution
Wildfires
Biodiversity Loss

Soil

Soils are complex mixtures of minerals, water, air, organic matter, and organisms (decaying remains of once-living things).
Soil is the "skin of the Earth" and supports plant life, vital to life on Earth.

Soil Types

Sand: Used in construction materials, landscaping, glass manufacturing, and metal casting.
Clay: Has very small particles, allowing little drainage. When wet, it becomes sticky and heavy, making it difficult for some plants to grow. Used in construction (adobe bricks), ceramics, and sculptures.
Silt: One of the most fertile soil types, with rich nutrients and good drainage.
Loam: A combination of sand, silt, and clay, providing a good balance of drainage and nutrient retention.

Soil Horizon

C Horizon - Parent Rock: Made up of broken-up bedrock, making it hard and difficult for plant roots to penetrate.
R Horizon - Bedrock: Consists of un-weathered igneous, sedimentary, and metamorphic rocks. Highly compact, making up bedrock.

Solid Waste

Solid waste includes useless or unwanted waste from human and animal activities that is normally solid.

Types of Solid Waste

Industrial Waste: Produced by mines, farms, and industries.
Municipal Solid Waste: Garbage or trash from homes, institutions, businesses, workplaces (excluding factories).

Sources of Solid Waste

Residential: Non-hazardous waste from households, such as kitchen waste.
Agricultural: Solid waste produced by agricultural activities, including food residues, animal dung, and crop residues.
Commercial: Non-hazardous waste from business establishments like shops and food establishments.
Industrial Wastes: Wastes from industrial processes, often including toxic and hazardous materials.
Institutional Solid Waste: Non-hazardous waste from public and government institutions, such as offices, religious institutes, schools, and universities.
Hospital Solid Waste: Includes both non-hazardous and hazardous waste from hospitals.

Solid Waste Disposal

Open Dumping: Waste is spread over a large area, attracting pests like flies and rats.
Controlled Tipping/Burial Sanitary Landfill System: Waste is placed in a trench, compacted, and covered with earth at the end of each work day.
Incineration: Burning combustible waste components at high temperatures to destroy contaminants, reducing waste volume by 20-30%.

Mining

The extraction of valuable minerals or geological materials from the Earth's surface or subsurface.
Mining products have high economic value and are essential to mankind, including metals like copper, gold, zinc, and gems like rubies, sapphires, and diamonds.

Importance of Mining

Supplies materials for a wide range of applications, including construction, automobiles, houses, computers, satellites, electricity generation, and components for various gadgets.
Gems have high economic value and are considered status symbols.
An economically important industry for regions and countries with mineral resources.

Types of Mining

Surface Mining: Removing shallow mineral deposits by clearing vegetation, soil, and rock (overburden), which is then deposited in piles of waste material called "spoils." Used to extract about 90% of non-fuel mineral resources.
