Which of the following are ways that humans have degraded natural capital to meet their own needs and wants?
- A.
Increasing use of the Earth's net primary productivity
- B.
Relying mostly on polluting and climate-changing fossil fuels
- C.
Using some renewable resources faster than they can be replenished
- D.
Eliminating many natural predators and reducing biodiversity
- E.
All of these answers
Correct Answer
E. All of these answersExplanation
Humans have degraded natural capital in multiple ways to meet their own needs and wants. One way is through the increasing use of the Earth's net primary productivity, which refers to the amount of energy that plants capture through photosynthesis and make available to the rest of the ecosystem. By exploiting this productivity, humans deplete the resources that support life on Earth. Another way is by relying mostly on polluting and climate-changing fossil fuels, such as coal, oil, and natural gas, which not only contribute to air pollution but also contribute to climate change. Additionally, humans have been using some renewable resources faster than they can be replenished, leading to their depletion. Lastly, humans have been eliminating many natural predators and reducing biodiversity, which disrupts ecosystems and can have cascading effects on the environment.Rate this question:

The population change in a particular area or country in a particular year can be calculated by
- A.
(deaths + emigration) (births + immigration)
- B.
(births + immigration) (deaths + emigration)
- C.
(deaths + immigration) (births + emigration)
- D.
(births + emigration) (deaths + immigration)
- E.
(births + deaths) (immigration + emigration)
Correct Answer
B. (births + immigration) (deaths + emigration)Explanation
The correct answer is (births + immigration) (deaths + emigration). This formula takes into account the number of births and immigration as factors that contribute to population growth, and the number of deaths and emigration as factors that contribute to population decline. By multiplying these two factors together, we can calculate the net population change in a particular area or country in a particular year.Rate this question:

The actual average replacement-level fertility for the whole world is slightly higer than
- A.
One child per couple
- B.
Two children per couple
- C.
Three children per couple
- D.
Four children per couple
- E.
Six children per couple
Correct Answer
B. Two children per coupleExplanation
The correct answer is two children per couple. Replacement-level fertility refers to the number of children a couple needs to have in order to replace themselves in the population. In order to account for infant mortality and individuals who do not reproduce, the replacement-level fertility rate is slightly higher than two. This means that on average, each couple needs to have slightly more than two children to ensure population replacement.Rate this question:

Which of the following would decrease the likelihood of a ocuple having a child?
- A.
The child is part of the family labor pool
- B.
Contraceptives are not available
- C.
They have no public or private pension
- D.
Women have many opportunities to participate in the work force
- E.
Infant mortality rates are high
Correct Answer
D. Women have many opportunities to participate in the work forceExplanation
When women have many opportunities to participate in the workforce, it often leads to delayed childbearing or having fewer children. This is because women may prioritize their careers and choose to have children later in life, or they may opt to have fewer children in order to balance their work and family responsibilities. Therefore, the likelihood of a couple having a child decreases when women have more opportunities to participate in the workforce.Rate this question:

Two useful indicators of overall health in a country or region are
- A.
Birth rate and death rate
- B.
Replacement-level fertility rate and total fertility rate
- C.
Life expectancy and infant mortality rate
- D.
Life expectancy and death rate
- E.
Life expectancy and population growth rate
Correct Answer
C. Life expectancy and infant mortality rateExplanation
Life expectancy and infant mortality rate are two useful indicators of overall health in a country or region. Life expectancy represents the average number of years a person is expected to live, which can reflect the overall health conditions, access to healthcare, and quality of life in a population. On the other hand, infant mortality rate measures the number of infant deaths per 1,000 live births, indicating the quality of healthcare, nutrition, and social conditions for newborns. By considering both life expectancy and infant mortality rate, we can gain insights into the overall health and well-being of a population, including the effectiveness of healthcare systems and social policies.Rate this question:

Family planning, economic opportunities for women, and schooling for girls generally produces a higher birth rate.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because family planning, economic opportunities for women, and schooling for girls generally result in a lower birth rate. When women have access to family planning methods, they can choose the number and timing of their pregnancies, leading to smaller family sizes. Economic opportunities for women often result in delayed marriages and childbearing, as women prioritize their careers. Additionally, when girls receive education, they are more likely to delay marriage and childbearing, leading to lower birth rates.Rate this question:

Birth and death rates generally decline as countries develop economically.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
As countries develop economically, the standard of living generally improves, leading to better healthcare, education, and access to resources. This, in turn, tends to result in a decline in birth and death rates. Improved healthcare means that fewer people die from preventable diseases, while better education and access to contraception lead to a decrease in birth rates. Therefore, it is true that birth and death rates generally decline as countries develop economically.Rate this question:
