SY25 AICE Environmental Management Semester Exam Review

What are the benefits of reintroducing captive-bred animals into the wild?

• It helps restore population numbers and biodiversity in ecosystems, contributing to ecological balance.

• It increases the chances of extinction for wild populations.

• It reduces the genetic diversity of the species.

• It has no significant impact on the ecosystem.

What is sustainable development?

• A development approach that prioritizes economic growth over environmental protection and social equity.

• A development approach that meets the needs of the present without compromising the ability of future generations to meet their own needs, balancing economic growth, environmental protection, and social equity.

• A strategy focused solely on environmental conservation without regard for economic growth.

• A method of development that only considers social equity and ignores environmental and economic factors.

What is the impact of a growing elderly population on the dependency ratio?

• A growing elderly population decreases the dependency ratio, as there are fewer dependents requiring support from the working-age population.

• A growing elderly population has no effect on the dependency ratio.

• A growing elderly population increases the dependency ratio, as there are more dependents requiring support from the working-age population.

• A growing elderly population temporarily affects the dependency ratio but stabilizes over time.

What is biodiversity, and why is it important?

• Biodiversity refers to the variety of life in a particular habitat or ecosystem, and it is important for ecosystem resilience and maintaining ecological balance.

• Biodiversity is the number of species in a given area, and it is important for tourism and recreation.

• Biodiversity is the genetic variation within a species, and it is important for agricultural productivity.

• Biodiversity is the total number of organisms on Earth, and it is important for climate change mitigation.

What is the relationship between migration rates and dependency ratios?

• Higher migration rates can potentially lower dependency ratios if migrants are primarily of working age, thus increasing the labor force.

• Higher migration rates increase dependency ratios by adding more dependents to the population.

• Migration rates have no effect on dependency ratios regardless of the age of migrants.

• Lower migration rates can decrease the labor force, leading to higher dependency ratios.

What is the dependency ratio?

• A measure that compares the number of dependents to the working-age population.

• A ratio that indicates the average age of a population.

• A calculation of the total population divided by the number of workers.

• A measure of economic productivity per capita.

How does rising life expectancy affect the economy?

• It increases the workforce and boosts economic growth.

• It can strain economic resources due to increased healthcare and social support needs.

• It has no significant impact on the economy.

• It leads to a decrease in the population's productivity.

What are the consequences of increasing birth rates on the dependency ratio?

• Increasing birth rates can lower the dependency ratio, as there will be fewer children who depend on the working-age population for support.

• Increasing birth rates can raise the dependency ratio, as there will be more children who depend on the working-age population for support.

• Increasing birth rates have no effect on the dependency ratio, as it remains constant regardless of population changes.

• Increasing birth rates can decrease the overall population, thus lowering the dependency ratio.

How does deforestation in tropical rainforests contribute to climate change?

• It decreases the amount of carbon dioxide in the atmosphere.

• It increases carbon dioxide levels in the atmosphere, as trees that absorb CO2 are removed.

• It has no effect on climate change.

• It helps in the growth of other plants by providing more sunlight.

How does an ageing population affect the economy?

• It increases the availability of skilled workers as more people retire.

• It can reduce economic growth by decreasing the availability of skilled workers, as more individuals retire and fewer young people enter the workforce.

• It has no significant impact on the economy.

• It leads to higher levels of innovation due to experienced workers.
