INTRO Take atmosphere for granted
Release waste in atmosphere
Damage the air qualityFrom burning coal, industrial, &
transportCause health issuesEffects vegetationAnimal life
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
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 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
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
