1. Plastics https://www.youtube.com/watch?v=Se12y9hSOM0

2. Energy Sources Non-renewable
-Ancient remains of plants and animals that took millions of years to form.
-Limited supply
-Fossil fuels
Ex: Petroleum, Natural Gas, Coal
-Sources of pollution: CO2, CO, SO2, Lead, Arsenic, NO2
Renewable
Infinite supply
Little to no pollution
Examples:
Wind, Solar, Geothermal, Biomass, Hydroelectric

4. Acid Rain
pH below 6
Results from the burning of fossil fuels (Oil, Natural gas, Coal).
Gases produced (NOx, SO2) combine with water vapor and form Nitric or Sulfuric Acid. This will fall as rain.
Harms plants and aquatic organisms by changing the soil and water pH.
Reduction in the amount since CAA 1990 amendment.

5. ACID RAIN/ACID DEPOSITION
- Acid rain has a pH 5.6 and below

6. ACID RAIN

8. Primary Pollutants
Secondary Pollutants

Natural
Stationary CO
CO2
SO2 NO
NO2
Most hydrocarbons
Most suspended

SO4 2

9. Ozone (O3)
In the Stratosphere, O3 filters harmful UV light= good for organisms.
In the Troposphere, excess O3 is created by the burning of fossil fuels= bad.
Depletion in stratosphere caused by Chloroflurocarbons.
1 Cl atom can break apart 100,000 O3

10. Greenhouse Effect
Natural heating of the earth’s surface with greenhouse gases (H2O, CO2, CH4…)

11. Global Warming
The planet’s temperature is slowly increasing as a result of excess CO2
Some scientists predict that:
1. Polar ice caps will melt and cause
flooding.
2. Severe storms will become more
common.
3. Serious droughts will occur.

12. How do we stop it? Reduce combustion of fossil fuels. Drive less cars.
No Coal, Oil, or Natural gas power plants.
Reduce your personal electricity consumption.
Recycle manufactured materials.
Write your congressman, Protest!

13. Invasive Species: Non-Native Species enter an ecosystem
Invasive Species, Alien Species, Non-Native Species are all the same.
Compete with native species and WIN!
Makes native species endangered or extinct.

14. Water Loss Lost by human consumption: Results in Salinization and
Drinking Water for giant cities
Irrigation for crops
Industry use and pollution
Farm Pollution
Results in Salinization and
Desertification.
Loss of Biodiversity

15. Monoculture Growing of one variety of plant.
Loss of organic nutrients that would be recycled.
Run-Off pollutes drinking water and aquatic ecosystems with fertilizer and pesticides.
Loss of natural habitat = loss of biodiversity = extinct species

16. Deforestation
Cut trees down for lumber, agriculture, and human settlements.
Destroys habitat for organisms- #1 cause for species becoming endangered
Removes CO2 absorbing trees that stop global warming.
Results in massive soil erosion.

17. E-waste(Technological Waste)
Electronic trash builds up.
Leaching of heavy metals and carcinogenic chemicals into the water and air.
Use up non-renewable resources.
