Causes of Atmospheric Pollution

Unit 3.2: page 125 in the Textbook

Carbon Dioxide: http://www.epa.gov/climatechange/emissions/co2_human.html

Sources:

1. Deforestation and burning wood

2. Burning fossil fuels

Effects: 

1. Traps more of the heat radiated from the surface

2. Increases Earth's atmosphere, causing Global Warming

3. Rising sea levels

4. Changes in world weather

Sources: 

1. Propellants in aerosol spray cans - hair spray, deodorants, insect killers

2. Coolants used in refirgerators and air-conditioning systems

Effects:1. Persist in the atmospehre for a long time, causing the breakdown of the Ozone System (hole in the ozone layer over Antartica)

Page 135: Methane http://epa.gov/methane/sources.html

Sources:

1. Deforestation

2. Decomposition of waste

3. Rice and cattle farming (rotting vegetation)

Effects:

1. Contributes to Greenhouse gases, leading to:

Rising sea levels, changes in world weather and global warming
