* Carbon Footprints * 1. What do you think the term “carbon footprint” means? * a. is it desirable to have a big one or a small one? Why? * http://www.youtube.com/watch?v=AGRlo87oAUg * * Definition: the measured amount of carbon dioxide (CO2) emitted through combustion fossil fuels. * The footprint is the amount of carbon-based natural resources consumed by person, company, community, country over a time period * On a large scale, it is expressed in tons while for an individual/household, it is calculated in pounds * CO2 & greenhouse gases are believed to be the cause of climate change & global warming. * http://www.discovery.com/video-topics/other/what-you-needto-know-carbon-footprint.htm * * 2. List ways you could decrease your carbon footprint. * Share & discuss * 3. Which of these options do you think most people would be willing to do? * Consider: replace 3 light bulbs with compact fluorescents saves 300 pounds; increase the thermostat from 68 to 70 (2,000 pounds); take shorter showers (350 pounds), turn off electricity not being used (1000 pounds); install solar panels * http://www.howcast.com/videos/365-How-to-Reduce-YourCarbon-Footprint * * 4. Estimate your carbon footprint * a. Let’s calculate it! * http://myfootprint.org/en/ * 5. How – if at all – do you expect climate change to affect you during your lifetime? * a. What about the next generation? * http://www.youtube.com/watch?v=_EWOrZQ3L-c * What is the impact of humans? * * Let’s read about Eco-Footprints *
