Social impact of technology power point

  1. 1. Technology is Destroying our Planet The Automobile and Global WarmingBy Brody Johnston
  2. 2. The Automobile The Automobile is the mostrevolutionary piece of technology toemerge from the field of transportation.The impact cars have had on our societyis tremendous. Allowing people to travellong distances in a very short amount oftime. It is estimated that there areabout 600 million vehicles in the world.From this it is obvious that theautomobile has impacted our society in aserious way; not just economically, orsocially, but also environmentally.
  3. 3. Pros of the Automobile Technology that revolutionized the way we trade, transport people and goods. The ability to travel where and when you want at a moments notice. Faster response time in emergencies (ambulance, police, fire trucks, etc.). Faster, more localized transportation of goods and services. Overall societal Independence
  4. 4. Cons of the Automobile Cars are expensive, (insurance, gas, maintenance fees, etc.). Can be deadly. Collisions in cars is the #1 cause of teenage deaths. Causing our society too be unhealthy and lazy due to lack of exercise. The increase in car users is causing a lot of congestion on the roads. Negative Impact on the environment:Cars exhaust fumes are causing global warming.
  5. 5. What is Global Warming? Global warming is defined as,“The progressive gradual rise ofthe earths surface temperaturethought to be caused by thegreenhouse effect andresponsible for changesin global climatepatterns” (Natsource).
  6. 6. The Effects of Global Warming Why is Global Warming such a big deal? Global warming is having a huge impact on our planets climate today. The increase of the Earths temperature, is slowly causing a variety of problems. Floods, and bigger and stronger storms are some of the smaller immediate issues. Global warming however, has the power to destroy our planet.
  7. 7. The Increase in3 Main Greenhouse Gas EmissionsCausesof GlobalWarmingGlobalDeforestation The Depletion of the Ozone Layer
  8. 8. Cars and Greenhouse Gases The majority of cars on Earth burn fossil fuels. (Gasoline, Diesel, oil, etc.). The combustion of theses fossil fuels releases pollutants into the atmosphere. These pollutants are known as Greenhouse gases, released from the cars muffler.
  9. 9. Greenhouse Gases Greenhouse gases are the number one cause for global warming. Released into the atmosphere primarily through the Combustion of fossil fuels in cars, factories, and electricity production. Greenhouse gases are made up of CO2, nitrous oxide, and methane (All released from automobiles exhaust). CO2 causes a greater temperature increase than any other gas.
  10. 10. Trees and Carbon Dioxide Animals produceCO2, and plantsproduce oxygen. Natural Harmony DeforestationDisrupts this process. Trees store CO2, they are a naturally occurring defence against the buildup of CO2 in our atmosphere from pollutants such as car exhaust.
  11. 11. Deforestation As we continue to become a more technologically advanced society, the amount of industry increases. More Cars = More Carbon Dioxide With more industry we are also seeing more deforestation. Less Trees = more Carbon Dioxide More CO2 = More damage to ozone layer
  12. 12. Ozone Depletion Ozone Depletion is the number one cause for the increase in temperatures world wide. Ozone Depletion is caused from the release of greenhouse gases. Holes in the ozone layer allow UV rays into our atmosphere. CO2 build up in our atmosphere traps heat(The suns UV rays)at the surface. Hotter surface temperatures = colder temperatures in the ozone layer. The colder the temperature in the ozone layer, the harder it is for the ozone to naturally replenish.
  13. 13. Evidence of Ozone Depletion By the year 2000, 60% of the ozone layer covering the Arctic region was lost. Currently over the Antarctic the ozone hole is three times the size of the United States. This is why the Arctic regions areshowing the greatesttemp increases.
  14. 14. The Automobiles Impact on Climate The automobile was invented in the early 1900’s. During the Industrial Revolution. The Industrial Revolution caused a higher % of greenhouse gas emissions. This pollution results in higher global temperatures. The global temperatureaverage has risen 0.7degrees Celsius sincethe 1900’s.
  15. 15. Evidence of Climate Change In 2006 24% of the ice in the polar arctic region disappeared. It was this same year that the Northwest Passage was free of ice for the first time in recorder history.
  16. 16. Effects of Global Warming The Arctic Regions house 96% of the glacier ice on Earth. If it melted, sea levels would rise up to 25ft world wide.  The damages this would cause would be incomprehensible  If not taken seriously global warming will destroy our planet.
  17. 17. Video on the Effects of Global Warming
  18. 18. How to Beat Global Warming  To improve our chances of stopping global warming there are a few things we as a society can do… Drive less/walk more = fewer emissions. Get your car E-Tested or consider buying an electric car. Reduce, Re-use, Recycle. Cut down on electricity Use less heat/air conditioning Buy more energy efficient products
