Types of pollution are-

1.Air Pollution.

2.Water Pollution.

3.Noise Pollution.

4.Land Pollution.

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

1.Smoke from chimneys of factories.The Police - Synchronicity 2 - YouTube2.Smoke from Vehicles.

Discuss L.A, TORONTO, LONDON’S MOTHS , Beijing

3.Smoke from fires.

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

1.We should share vehicles for going to office.

2.We should get a regular pollution check of our vehicle. (RETIRE YOUR RIDE, CASH FOR CLUNKERS)

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.

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

1.Factories throw their waste in water bodies.

2.People bathe and wash clothes in water bodies.

3.Some oil ships drown in water which hardly effects the aquatic life.

4.Smoke from vehicles let the river to dry.

Page 5: Types of pollution are- 1.Air Pollution. 2.Water Pollution. 3.Noise Pollution. 4.Land Pollution.

1.Factories should not throw their waste in water bodies.

2.People should not bathe and wash clothes in rivers or lakes.

3.People should not take their animals to take baths in rivers or lakes.

Page 6: Types of pollution are- 1.Air Pollution. 2.Water Pollution. 3.Noise Pollution. 4.Land Pollution.

1.Jet planes.

2.Loud speakers and other loud speaking things.

3.Cinema halls.

4.Factories

5.Road traffic

Page 7: Types of pollution are- 1.Air Pollution. 2.Water Pollution. 3.Noise Pollution. 4.Land Pollution.

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.

Page 8: Types of pollution are- 1.Air Pollution. 2.Water Pollution. 3.Noise Pollution. 4.Land Pollution.

1.People Cut forest for furniture.

2.Plastic is the main source of land pollution (and sea).

3.People throw house garbage on roads.

4.Some industries throw their waste on land.

Page 9: Types of pollution are- 1.Air Pollution. 2.Water Pollution. 3.Noise Pollution. 4.Land Pollution.

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.

•“Since only 3% of oil sands oil has been used to date…”game over” for environment if we burn it all.”-Keystone xl rejected by State dept and Obama- “Big Oil’s” first REAL loss usually $ talks

• Obama says still wants US to move away from foreign oil -Environmentalists, scientists and native groups won. -Republicans demanded a decision before November election and forced Obama to rush-play to his constituents

• Trans Canada can reapply. Harper unhappy. Will sell to China.
