Air

Pollution

Station 1

Causes of Air Pollution

• Features surrounding an area.• For example, if a city is surrounded by mountains it

traps the polluted air. • Human activity is a major cause of air pollution,

especially in large cities. • Factory smoke• Car and Airplane smoke

• Burning Fossil Fuels • Fossil fuels include coal, oil, and natural gas.

• Smoke + Fog = Smog

Effects of Air Pollution

• Acid Rain• Asthma and pneumonia are linked to vehicle emissions.• It burns the lungs, nose, and eyes, and endangers

human life.• It also blackens buildings and harms wildlife.

City surrounded by Mountains

Solutions for

Air Pollution

• Alternative fuel sources for cars.• Building factories that don’t pollute the air.• Laws that require cars to produce less pollution.• Encouraging people to walk or ride bikes/buses, rather

than driving.

Acid

Rain

Station 2

What is Acid Rain?

• Toxins in Air Pollution get absorbed into clouds and it creates acid rain.

• It’s not acidic enough to burn your skin, but it is very harmful for the environment.

Causes of Acid Rain?

• Smoke from factories • Burning fuels like natural gas, coal, & oil.• The economy depends on these factories.

• Cars & buses also produce harmful gases.

Effects of Acid Rain?

• Destroys nutrients and minerals in the soil.

• Damage or kill trees. • Pollute lakes enough to kill fish.• Houses, buildings, and statues can also

be damaged.

environment.

Before After

Solutions for Acid Rain?

• Building factories that don’t pollute the air.

• Laws that require cars to produce less pollution.

• Encouraging people to walk or ride bikes/buses, rather than driving.

Water

Pollution

Station 3

According to this cartoon, What causes water Pollution? (There is more than one answer!!!!!!)

Causes of

Water Pollution

• Sewage.• Pesticides and fertilizers from farms. • Waste from factories.• Trash from people littering. • Acid Rain. • Oil spills.

Effects of

Water

Pollution

• Bacteria in the water can develop.

• Can destroy marine habitats.

• Drinking dirty, polluted water can make humans sick. It can make people so sick that they can die.

Solutions

for

Water

Pollution

• Reducing the amount of wastes dumped into water source.

• Reducing air pollution.

• Enforcing regulations for oil industries.

Over-

Extraction

of Resources

Station 4

What is

Over-Extraction

• The extraction (removal) of minerals and metals from earth.

What do you think

this cartoon is

saying about

mining?

Causes of

Over-Extraction

• Some countries economies rely heavily on their natural resources.

• Removing too many natural resources.

Effects of

Over-Extraction

• Mining is very destructive to the environment.

• Causes deforestation. • In order to mine, trees and

vegetation are cleared and burned. • Causes water pollution. • Chemicals that are used for mining

are discharged into rivers, streams, bays, and oceans.

Solutions for

Over-Extraction

• New mining laws.• Reduce pollution to water sources.• Limit deforestation.

• Reuse and recycle products. • That means we will have less to mine

from the Earth.• Conserve energy because then we won't

have to mine so much oil, gas, and coal.

Deforestation

Station 5

What is

Deforestation?

• The cutting, clearing, and removal of forest.

Causes of Deforestation

• Logging• Mining• Oil and gas extraction• Cattle ranching• Agriculture: Cash crops

Effects of

Deforestation

• Loss of animal habitats • Extinctions of plants, insects, animals, indigenous

peoples, etc. • Desertification

• Soil erosion occurs when trees and plants are removed and top soil is blown away.

• Creating dry land that slowly turns into deserts • Climate change • Pollution

Solutions for Deforestation

• Seedlings are planted each year.• Passing laws on cutting down too many trees.• What else do you think can be done?

Oil

Pollution

Station 6

Causes of

Oil

Pollution

• Some countries economies rely on oil drilling. • Accidents• Equipment

breaks down.• Natural

disasters can damage equipment or oil holding facilities.

Effects of

Oil Pollution

• Kills wildlife.• Hurts fishing industry.

• Pollutes bodies of water.

Solutions for

Oil Pollution

• Use renewable energy sources. • Clean-up and prevention of oil spills.
