I need help with an answer to the following for my study guide.

Carbon dioxide emissionsRising or falling?We presented evidence earlier that per capita consumption of water, energy, and solid objects like plastics and metals has been constant or falling in recent decades. The -consumption of fossil fuels, however, is of special concern because of -worries about global warming caused by the emission into the atmosphere of carbon dioxide and other so-called greenhouse gasses. Go to the Energy Information Agency's Environment page,www.eia.doe.gov/environment.html. Scan the International Emissions Data links and click on the one that says Per Capita Emissions in order to open up an Excel spreadsheet that contains per capita carbon dioxide emissions for almost all countries for each of the previous 20 years or so. Have per capita carbon dioxide emissions in the United States, Japan, and France grown, stayed about the same, or fallen over the past couple of decades? Does it surprise you to learn that over this time period France has moved to generate more than 80 percent of its electricity from nuclear power, which emits no carbon dioxide? What about emissions in China, Indonesia, and India? Why have emissions risen so much (in percentage terms) in these countries? (Hint: They are not as poor asthey used to be.) If current trends in these countries continue, should we be worried? And could defining property rights over the atmosphere solve the problem?
