All Flashcards
How does access to family planning affect population growth?
Contraception and reproductive health services can lower birth rates.
How does education, especially for women, impact birth rates?
Education for women is linked to lower birth rates.
How does industrialization affect population growth?
It leads to improved sanitation, increased food production, and medical advances, resulting in exponential population growth.
Describe the Rule of 70.
A quick way to estimate how fast a population is growing by dividing 70 by the percentage growth rate to find the doubling time.
What is the impact of resource availability on population growth?
Limited resources (food, water, territory) restrict population growth, acting as a density-dependent limiting factor.
How do natural disasters affect population size?
Natural disasters are density-independent factors that can drastically reduce population size regardless of the initial population density.
What is the relationship between human population growth and resource depletion?
Human population growth is directly linked to increased resource depletion, pollution, and habitat loss.
What is the effect of improved sanitation on population?
Reduced disease spread, leading to lower death rates and population growth.
What is the effect of increased food production on population?
Better nutrition, leading to lower death rates and population growth.
What is the effect of medical advances on population?
Longer, healthier lives, leading to lower death rates and population growth.
How does competition affect population growth?
Increased competition for resources leads to decreased birth rates or increased death rates, limiting population growth.
How does disease affect population growth?
Disease spreads more easily in dense populations, leading to increased death rates and limiting population growth.
How do extreme weather events affect population growth?
Extreme weather events (storms, droughts, heatwaves) can cause a sudden decrease in the population.
What is the effect of improved sanitation on population?
Reduced disease spread, leading to lower death rates and population growth.
What is the effect of increased food production on population?
Better nutrition, leading to lower death rates and population growth.
What is the effect of medical advances on population?
Longer, healthier lives, leading to lower death rates and population growth.
What is the effect of a tsunami on population?
Sudden decrease in population size, regardless of the initial population.
What is the effect of a drought on population?
Limits resource availability, potentially leading to decreased birth rates or increased death rates.
What is the effect of increased competition on population?
Can lead to decreased birth rates or increased death rates as resources become scarce.
What is the effect of disease outbreak on population?
Increased death rates, especially in dense populations.
What is the effect of high birth rates and immigration on population?
Increase in population size.
What is the effect of high death rates and emigration on population?
Decrease in population size.
What is the effect of resource depletion on population?
Can lead to decreased carrying capacity and potential population decline.
