AIR RESOURCES

neno, michelle, jovil, ryan

INTRO Take atmosphere for granted

Release waste in atmosphere

Damage the air qualityFrom burning coal, industrial, &

transportCause health issuesEffects vegetationAnimal life

Acid Rain

ACID RAIN DEFINITION

Precipitation containing high amount of acids due to industrial gas emission sulfur dioxide and nitrogen oxides

CAUSE OF ACID RAIN

When industries release too much SO2 and NOx in the atmosphereBurning of fossil fuels

EFFECTS OF ACID RAIN Forest: Affects root system of trees

Slows growthkills vegetationSoil degradation

Lakes and Rivers: Affect water cycleKills aquatic lifeFish die and eggs no hatch Migrate

EFFECTS OF ACID RAIN CON’T Farming: Root system of crops unable to

absorb nutrients damage the crops that grow in the soilLose millions of dollars

Buildings and Vehicles - Causes corrosion

Health issues – Can cause death Respiratory disease

ACID RAIN REDUCTION

Burn less fossil fuels globally

Stricter laws to reduce SO2 and NOx emissionsEspecially in developing countries

OZONE DEPLETION DEFINITION

Destruction of the stratospheric ozone layer which shields the earth from ultraviolet radiation harmful to life

http://www.brainpop.com/science/earthsystem/ozonelayer/

OZONE DEPLETION CAUSES

chlorine and nitric acid in the atmosphere.Most of the chlorine comes from CFC’s

OZONE DEPLETION EFFECTS

Ultraviolet Rays can cause Skin cancerEye damagesDamage immune system Damage plant growth

Fish stocks decline ‘cause algae damaged lead to marine life dying off

STOPPING OZONE DEPLETION

24 nations signed Montreal Protocol they pledged to reduce ozone depleting gasses

Replace use of CFC’s for chemical companies

Easier to protect ozone layer ‘cause it causes skin cancer and damages eye and it is easier to stop it by reducing CFC

Ozone regulation has had an affect Montreal Protocol: reduction in CFCs seems to be

working

NATURAL GREENHOUSE EFFECT

warming of the atmosphere by the trapping of long wave radiation going upC02 most important

GLOBAL WARMING DEFINITION

an increase of Earth’s temperature that change the climate may result from green house effect

Global Warming

CAUSES OF GLOBAL WARMING

Increase in greenhouse effect

Burn of fossil fuels Release CO2 in

air Methane gass CFC’s threat to

the ozone layer

EFFECTS OF GLOBAL WARMING

Rise in sea level Cause of melting of ice in Arctic and Antarctic

Climate change Forest fires Changes in fish migration Plants

Increase in tempt problem for food growth Farm

Increase in tempt, ruin crop belts Dry out crops

STOPPING GLOBAL WARMING

Reduce CO2 emission in air

Plant tress Stop

deforestation Takes in CO2

STOPPING GLOBAL WARMING Kyoto protocol

Countries agree to reduce emission of six green house gases that contribute to Global Warming

setback when U.S. withdrew from the Kyoto Protocol ‘cause they release most green house gasses

Developing nations don’t agree cause slow or stop their economic development.

Easier to stop ozone then climate change Cause

QUIZ

ANSWERS1. A2. C3. D4. B5. D

6) Ozone Depletiona) CFC’s in airb) Damage eye, skin cancer, damage immune

system c) i)use CFC friendly products

ii) strict laws on factories limit CFC use

Climate Change:1) Forestry

• Rise tempt dry out crops• Rise tempt cause forest fires

2) Fishing • Acid rain kill fishies, eggs no hatch • Rise tempt cause fish to migrate

3) Tourism• Snow condition affect tourism for skiing etc.• Kill biodiversity as some animals need cold
