1. The United Nations has recently produced population projections out to the year 2150, available through their Population Division web site.
   
   Locate the most recent population projections. What are the low, medium, and high global population projections for 2050? What are the projections for 2150? Summarize the different assumptions used in the low, medium, and high scenarios.
   
   Estimate the current percentage of global population living in Africa, Latin America, and Asia (excluding China and India). How will this percentage change in 2050 and 2150 under the medium population scenario? What do you think are the environmental implications of this change in population distribution? Specifically, do you think the change in geographical distribution will result in higher or lower environmental impacts?
   
   
2. Go to the United Nations' "Population, Environment, and Development" wall chart.
   
   Compare economic development, as measured by GDP per capita, with population growth rates for the "more developed", "less developed", and "least developed" countries. Is lower per-capita GDP associated with higher population growth rates? Does this necessarily imply that efforts to raise GDP will lower population growth rates? Explain.
   
   Review the country-specific data on per-capita GDP and population growth. Identify five countries that have both low population growth rates and low GDP. What might explain these unusual cases? Also, identify five countries that have high population growth rates and high GDP. Again, do you have any ideas why this occurs in some countries?
