Causes:
▪Human-Made Causes:
▪Industrial Discharges:
▪Factories and industrial plants release pollutants such as heavy metals, toxic chemicals, and organic
waste directly into water bodies.
▪Agricultural Runoff:
▪Use of pesticides, herbicides, and fertilizers in agriculture can wash into nearby water bodies,
causing nutrient pollution and chemical contamination.
▪Sewage and Wastewater:
▪Untreated or inadequately treated sewage and wastewater from households and industries can
introduce harmful microorganisms, nutrients, and chemicals into water bodies.
▪Plastic and Solid Waste:
▪Improper disposal of plastic products and other solid waste leads to pollution in rivers, lakes, and
oceans.

10. ▪Natural Causes:
▪Sedimentation:
▪Natural Erosion And Sediment Runoff Can Increase Turbidity And Reduce Water Quality.
▪Natural Disasters:
▪Events Such As Floods And Hurricanes Can Wash Pollutants Into Water Bodies.

of public transportation to reduce traffic noise. Improve road infrastructure to minimize
noise from vehicles.
❖Public Awareness and Education: Educate the public about the impacts of noise pollution
and encourage behaviors that reduce noise, such as using headphones instead of speakers
and maintaining vehicles and machinery.

16. Land pollution:
Land pollution is the degradation of the Earth's land surfaces
caused by the accumulation of solid and liquid waste materials,
chemicals, and other harmful substances. This pollution can result
from human activities such as industrial operations, agricultural
practices, mining, deforestation, and improper waste disposal.
Land pollution leads to the contamination of soil and groundwater,
loss of arable land, disruption of ecosystems, and adverse effects
on human health and wildlife.

17. Major causes of land pollution:
The Major Causes Of Land Pollution Are Largely Due To Human Activities. Here Are The Key
Contributors:
▪Industrial Activities:
▪Waste Disposal: Improper Disposal Of Industrial Waste, Including Chemicals, Metals, And Toxic By-products.
▪Manufacturing Processes: Release Of Pollutants During Production Processes.
▪Agricultural Practices:
▪Pesticides And Fertilizers: Overuse Of Chemical Pesticides And Fertilizers Can Contaminate Soil And Water.
▪Animal Waste: Large-scale Livestock Farming Produces Significant Amounts Of Waste.
▪Mining Activities:
▪Extraction Processes: Disruption Of Land Surfaces And Contamination Of Soil And Water Through Mining
Activities.
▪Waste Products: Accumulation Of Mining Waste, Including Tailings And Slag.

18. ▪ Urbanization and Construction:
▪Deforestation: Clearing of forests for urban development leads to soil erosion and loss of
biodiversity.
▪ Construction Waste: Debris and waste from construction sites.
▪ Waste Disposal and Landfills:
▪ Solid Waste: Improper disposal of household, commercial, and industrial waste in landfills.
▪ Hazardous Waste: Disposal of hazardous substances such as chemicals, batteries, and electronic
waste.
▪ Deforestation:
▪ Clearing of Forests: Removal of trees for agriculture, logging, and urban development leads to soil
erosion and loss of habitat.
