  1. Sustainability: Environment Lesson 2

  2. Review: • 1. What chemical is the cause of ozone layer depletion? • 2. What is the main source of SO2 and NO2 pollution that causes acid rain? • 3. What are some of the causes of Carbon Dioxide emissions in the atmosphere? • 4. What region of the world suffers from high levels of skin cancer?

  3. Acidification of lakes, rivers = negative effects on fish/wildlife

  4. “His nose is missing”

  5. Ozone Hole ~ shrinking? Thanks to Montreal Protocol

  6. Climate Change Issue

  7. Carbon Cycle & Tetris • https://www.youtube.com/watch?v=ztWHqUFJRTs

  8. Causes Industrial Pollution ~ Coal Vehicle Emissions

  9. Deforestation ~ Amazon

  10. Melting of Permafrost“Drunk Trees”

  11. Emissions by Region of World • Highest greenhouse gas emissions are by countries in the developing world • Brazil (Amazon) • China (coal, factories) • India (coal, factories) • BUT ~ MOST POLLUTION IN DEVELOPING NATIONS IS ACTUALLY BY-PRODUCT OF NORTH AMERICAN CORPORATIONS WHO HAVE OUTSOURCED.. • But Canada ranks 3rd highest in world per capita due to oil sands production ~ with Kinder Morgan + Gateway, rates will skyrocket

  12. Time Lapse Photo ~ google Earth • http://world.time.com/timelapse/

  13. Human Causes • KEY ACTIONS: • Cars • Factory Emissions - this is the BIG ONE • Deforestation of “the lungs of the earth” • Cattle Ranching ~ production of meat • Coal Use ~ specific regions of world • Other Factors ~ melting of permafrost, releasing stores of carbon dioxide

  14. Effects of Warming on Environment • Melting ice caps – which adds freshwater to ocean decreasing its salinity – affects ocean currents ~ rising sea levels • Melting permafrost – storage basin for massive amounts of CO2 – tipping point • “Weird Weather” – increasing numbers of storms, floods, hurricanes, tornadoes • Shifts in Climate Zones and Vegetation Patterns • Disease ~ Pine Beetle, etc. • Species Extinction • Wildfires

  15. Devastating Effects

  16. Effects of Warming on Humans • Displaced peoples – currently 25 million environmental refugees • Destruction of property, infrastructure • Increased poverty, and competition for resources • Increased drought – more pressure on fresh water • Increased famine – crops do not grow

  17. Flooding in India - 2008

  18. Connection to Poverty • 25 million environmental refugees ~ more than number of political refugees from places of war and conflict • Major cause of poverty and stops people from being able to meet their basic needs

  19. Solutions ~ “REAL” • R = Realistic • E = Education • A = Alternatives & Innovation • L = Legislation, Laws and Policy

  20. What Can We Do? • Kyoto Protocol ~ accord signed to reduce Greenhouse gasses, Canada refused to re-sign • G15 countries have come together to try and figure out new solutions… very little progress • Millenium Goal ~ Environment **** Push for environmental protection from government

  21. Other Approaches • Education ~ Reduce, Reuse, Recycle ~ use less plastic! (oil) • Thinking outside the box • New Ideas • Alternatives ~ Renewable Energy Sources • PASSION + GETTING OUT AND EXPERIENCING NATURE.. SEEING OUR PLANET

  22. What are your ideas? • List possible solutions to dealing with climate change • INDIVIDUAL ACTIONS + COLLECTIVE ACTION

  23. ALTERNATIVES ~ Big Belly & Giant Jelly Fish • https://www.youtube.com/watch?v=Ervb3qX_xi8 • https://www.youtube.com/watch?v=u0I-3wkH37w

  24. Solar Roadways ~ USA • Glass solar panels~ couple has raised 1 million dollars for project • that will generate electricity and lower energy cost ~ will heat roads + provide light http://techcrunch.com/2014/05/25/the-crazy-genius-behind-solar-roadways/

  25. Why We Need to Save Our Planet… • Hope for the Future…. Political activism and organization.. • Case Study: Sacred Headwaters • http://www.ted.com/talks/wade_davis_gorgeous_photos_of_a_backyard_wilderness_worth_saving
