  • 1. Technology is Destroying our Planet The Automobile and Global WarmingBy Brody Johnston
  • 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. 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. 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. 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. 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. The Increase in3 Main Greenhouse Gas EmissionsCausesof GlobalWarmingGlobalDeforestation The Depletion of the Ozone Layer
  • 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. 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. 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. 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. 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. 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. 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. 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. 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.

  • 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
