The document discusses four main types of pollution: air, water, noise, and land pollution. It provides examples and causes of each type of pollution, as well as suggestions for preventing or reducing each type of pollution, such as using public transportation and bicycles to reduce air pollution from vehicles, proper waste disposal to prevent water and land pollution, and limiting loud noises and sounds.

1. Types of pollution are-
1.Air Pollution.
2.Water Pollution.
3.Noise Pollution.
4.Land Pollution.

2. Air Pollution
 Air pollution is the human introduction into the
atmosphere of chemicals, particulate matter, or
biological materials that cause harm or discomfort to
humans or other living organisms, or damage the
environment .
 Examples of air pollution :
Smog
Acid rain
Indoor air pollution
Dust particles

3. 1.Smoke from chimneys of factories.
2.Smoke from Vehicles.
3.Smoke from burning of fire.

4. 1.We should share vehicles for going to office.
2.We should get a regular pollution check of our
vehicle.
3.We should use a bicycle for going to near by places.
4.Chimneys of factories should be fitted with proper
filters to prevent smokes from coming out and effect
atmosphere.

5. Water Pollution
Water pollution is the introduction into fresh or ocean
waters of chemical, physical, or biological material
that degrades the quality of the water and affects the
organisms living in it.
Examples of Water pollution :
Industrial affluents
Mining and Agricultural Wastes
Sewage Disposal and Domestic Wastes

6. 1.Factories throw their waste in water bodies.
2.People bath and wash clothes in water bodies.
3.Some oil ships drown in water which hardly
effects the aquatic life.
4.Smoke from vehicles lets the river to dry.

7. 1.Factories should not throw there waste in water
bodies.
2.People should not bath and wash clothes in rivers or
lakes.
3.People should not take there animals to take bath in
rivers or lakes.

8. Noise Pollution
Noise pollution is unwanted human-
created sound that disrupts the
environment. The dominant form of noise
pollution is from transportation sources,
principally motor vehicles, referred to as
environmental noise.
Examples of Noise Pollution:
Loudspeakers
Aircrafts

9. 1.Jet planes.
2.Loud speakers and other loud speaking things.
3.Cinema halls.
4.Factories
5.Road traffic

10. 1.We should not use loud speakers.
2.Factories should be made out of the city.
3.There should be not more noise making
vehicles on the roads.

11. Land Pollution
Land pollution is the degradation of the Earth's land
surface through misuse of the soil by poor
agricultural practices, mineral exploitation, industrial
waste dumping, and indiscriminate disposal of urban
wastes .
Examples of Land pollution :
Soil Pollution
Waste Disposal

12. 1.People Cut forest for furniture.
2.Plastic is the main source of land pollution.
3.People throw house garbage on roads.
4.Some industries throw their waste on land.

13. 1.People should not cut trees for making furniture.
2.People should not throw garbage on land.
3.Plastic bags should be avoided for prevention of land
pollution.
4.Industries should not throw there waste on land.
