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.

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.
![Page 12: Air Pollution · 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](https://reader033.fdocuments.us/reader033/viewer/2022052718/5f04bf9e7e708231d40f827f/html5/thumbnails/12.jpg)

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.
![Page 14: Air Pollution · 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](https://reader033.fdocuments.us/reader033/viewer/2022052718/5f04bf9e7e708231d40f827f/html5/thumbnails/14.jpg)
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.

• The extraction (removal) of minerals and metals from earth.
What do you think
this cartoon is
saying about
mining?
![Page 27: Air Pollution · 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](https://reader033.fdocuments.us/reader033/viewer/2022052718/5f04bf9e7e708231d40f827f/html5/thumbnails/27.jpg)
Causes of
Over-Extraction
• Some countries economies rely heavily on their natural resources.
• Removing too many natural resources.
![Page 28: Air Pollution · 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](https://reader033.fdocuments.us/reader033/viewer/2022052718/5f04bf9e7e708231d40f827f/html5/thumbnails/28.jpg)
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.
![Page 29: Air Pollution · 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](https://reader033.fdocuments.us/reader033/viewer/2022052718/5f04bf9e7e708231d40f827f/html5/thumbnails/29.jpg)

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.
