  1. Air Resources neno, michelle, jovil, ryan

  2. Intro • Take atmosphere for granted • Release waste in atmosphere • Damage the air quality • From burning coal, industrial, & transport • Cause health issues • Effects vegetation • Animal life

  3. Acid Rain

  4. Acid Rain Definition • Precipitation containing high amount of acids due to industrial gas emission • sulfur dioxide and nitrogen oxides

  5. Cause of Acid Rain • When industries release too much SO2 and NOx in the atmosphere • Burning of fossil fuels

  6. Effects of Acid Rain • Forest: Affects root system of trees • Slows growth • kills vegetation • Soil degradation • Lakes and Rivers: Affect water cycle • Kills aquatic life • Fish die and eggs no hatch • Migrate

  7. Effects of Acid Rain Con’t • Farming: Root system of crops unable to absorb nutrients • damage the crops that grow in the soil • Lose millions of dollars • Buildings and Vehicles - Causes corrosion • Health issues – Can cause death • Respiratory disease

  8. Acid Rain Reduction • Burn less fossil fuels globally • Stricter laws to reduce SO2 and NOx emissions • Especially in developing countries

  9. 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/

  10. Ozone Depletion Causes • chlorine and nitric acid in the atmosphere. • Most of the chlorine comes from CFC’s

  11. Ozone Depletion Effects • Ultraviolet Rays can cause • Skin cancer • Eye damages • Damage immune system • Damage plant growth • Fish stocks decline ‘cause algae damaged • lead to marine life dying off

  12. 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

  13. Natural Greenhouse Effect • warming of the atmosphere by the trapping of long wave radiation going up • C02 most important http://www.brainpop.com/science/ourfragileenvironment/globalwarming/

  14. Global Warming Definition • an increase of Earth’s temperature that change the climate • may result from green house effect

  15. Global Warming

  16. 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

  17. 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

  18. Stopping Global Warming • Reduce CO2 emission in air • Plant tress • Stop deforestation • Takes in CO2

  19. 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

  20. QUIZ

  21. answers 6) Ozone Depletion CFC’s in air Damage eye, skin cancer, damage immune system i)use CFC friendly products ii) strict laws on factories limit CFC use • A • C • D • B • D • Climate Change: • 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 conditions
