The world's three biggest areas of dense population are found in South Asia, East Asia, and Europe. But Africa is the world's fastest-growing area. Use Appendix 3 at the end of the Bjelland textbook (pages A13-23 of the 16th ed) to find the Rate of Natural Increase (as of 2019) of each of those three dense regions plus Africa. List the RNI for each region, and then find and list other data presented in that table (number of people? life expectancy? % urban? GNI-per capita? be sure to consider what GNI means in terms of purchasing non-essential items) that will enable you to consider the potential 'ecological footprint' (how much will that region 'cost' Earth to support its population?) of those four regions in 2050. Conclude with thoughtful judgments and your explanations for them about the ecological impact of those regions.
