Lesson Content/Board Summary

Types Of Environmental Pollution

Air Pollution

Air pollution occurs when harmful substances such as gases, smoke, or dust contaminate the atmosphere, making it unhealthy for humans, animals, and plants.
The following are the major causes of air pollution:

Emissions from vehicles and industries.
Smoke from burning of fossil fuels and waste.
Deforestation leading to increased dust and carbon dioxide.

Water Pollution

Water pollution is the contamination of water bodies by harmful substances, affecting aquatic life and human health.
These include:

Discharge of industrial effluents into rivers and lakes.
Oil spills and chemical runoff from farms.
Improper disposal of domestic waste and sewage.

Soil Pollution

Soil pollution occurs when chemicals, pesticides, or waste contaminate the soil, reducing its fertility and harming plants.
They are:

Excessive use of chemical fertilizers and pesticides.
Dumping of industrial and domestic waste on land.
Oil and chemical spills from factories and transportation.

Noise Pollution

Noise pollution is unwanted or harmful sound that affects human and animal health.
Examples are:

Loud music, traffic, and construction activities.
Industrial machinery and generators.
Noise from airports and public events.

Light Pollution

Light pollution is excessive or misdirected artificial light that disrupts natural cycles.
The following are common sources:

Streetlights and neon signs.
Residential and commercial lighting left on unnecessarily.
Vehicle headlights in urban areas.

Effects of Environmental Pollution

Environmental pollution can cause health problems, damage ecosystems, and reduce quality of life.
They include:

Respiratory diseases from air pollution.
Waterborne diseases from contaminated water.
Reduced soil fertility and crop yield.
Disturbance of natural habitats for animals.
Psychological stress from noise and light pollution.

Prevention of Environmental Pollution

Prevention involves actions to reduce pollution and protect the environment.
They include:

Proper disposal and recycling of waste materials.
Planting trees and maintaining green spaces.
Using public transport or cleaner energy sources.
