2 * 1. What do you think the term “carbon footprint” means? * 2. Do you think it is desirable to have a big one or a small one? Why? * http://www.youtube.com/watch?v=AGRlo87oAUg http://www.youtube.com/watch?v=AGRlo87oAUg

3 * 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. * 3. What is the big idea of this video? * http://www.discovery.com/video-topics/other/what-you-need-to-know- carbon-footprint.htm http://www.discovery.com/video-topics/other/what-you-need-to-know- carbon-footprint.htm

4 * 4. List ways you could decrease your carbon footprint. * Share & discuss * 5. Of your list (# 4), 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-Your- Carbon-Footprint http://www.howcast.com/videos/365-How-to-Reduce-Your- Carbon-Footprint
