QUESTION: Review What has accounted for the majority of the world’s population growth in recent years? Women are having more babies. Death rates have dropped due to technology, medicine, and food. More women are using contraceptives. Nothing; the population has dropped in recent years. © 2014 Pearson Education, Inc.

QUESTION: Review According to the I = P  A  T formula, what would happen if China’s 1 billion people had a lifestyle like that of Americans? Their population would automatically drop. Their population would automatically increase. Their affluence and technology would increase. Their impact on the environment would even out. © 2014 Pearson Education, Inc.

QUESTION: Review How does the current combination of population size and affluence (resource use) compare to the Earth’s available resources? Our ecological footprint is 50% larger than the Earth’s biocapacity. As long as the developed nations reduce their consumption, there will be ample resources. As long as developing nations slow their population growth, there will be ample resources. We have 3–4 decades before we need to change our growth or resource use patterns. © 2014 Pearson Education, Inc.

QUESTION: Review Describe the relationship between growth rates and population size. Falling growth rates automatically mean a smaller population. Falling growth rates automatically mean a larger population. Falling growth rates mean we no longer have a population problem. Falling growth rates do not mean a smaller population, but that rates of increase are slowing. © 2014 Pearson Education, Inc.

QUESTION: Weighing the Issues Would you rather live in a country with a larger population or smaller population? Small population, so there will be more resources for me Small population, so there will be more resources for others, including wildlife Large population, so I can find a date Large population, because people are our biggest resource © 2014 Pearson Education, Inc.

QUESTION: Interpreting Graphs and Data What happens during the “pre-industrial” stage of the demographic transition? High birth and death rates cause the population to increase. High birth and death rates keep the population stable. High birth rates with low death rates cause the population to increase. Low birth and death rates cause the population to decrease. © 2014 Pearson Education, Inc.
