Bio 105 OnlineYou’re Causing Rapid Climate Change WorksheetThe major component of any fossil fuel is carbon. It forms seventy-five percent of methane, the majorcomponent of high-grade natural gas. Carbon forms eighty-four percent of octane, which typifies mostgasolines, and it forms eighty percent of good anthracite coal.Now here's the catch. Since each carbon atom joins with two heavier oxygen atoms, CO2molecules aremuch heavier than the carbon in fuels. Each pound of fuel yields almost three pounds of CO2. Thattakes some digesting. Our first reaction is, "It's only a gas; it surely can't amount to much." But eachgallon of gasoline produces twenty pounds of carbon dioxide.Our consumption of fossil fuels has now caused the CO2content of Earth's air to be higher than itwould normally be. It's certainly impacting our climates. How much is subject to a pretty fierce debate,but global temperatures are definitely on the rise. While better analysts than I try to determine exactlywhat part of the rise comes from CO2greenhouse effects, we'd be crazy not to look for ways ofreducing the CO2in our air.Your CO2“footprint” is basically a measurement of how much carbon dioxide is emitted into theatmosphere as a result of your individual actions. Transportation choices are just one component of aCO2footprint - but can often be the most significant. How big isyourtransportation footprint? And howdoes it compare with that of your classmates? Through this activity you will calculate yourtransportation CO2
