State the type of ozone that is considered a pollutant.
Remember that ozone high up in the stratosphere is good; it protects us from harmful UV radiation. Ozone down here in the troposphere, however, is harmful to organisms. It interferes with photosynthesis in plants and can damage materials made of rubber. In humans, it can irritate the lungs, nose, throat and eyes.

Define CDR

Descirbe how increase in human population may imapct sustainability
An increase in humans will make our population more unsustainable than it already is. however we could be sustainable if we all use fewer resources and produce less wast throught a more circular economy that reuses materials

Describe two technocentric strategies that may help achieve environmental sustainability in urban planning.
Technocentric strategies that may help achieve environmental sustainability in urban planning include adopting renewable energy sources, for example solar panels and windmills, to reduce CO2 emissions from fossil fuels. Setting up efficient public transport, for example, electric buses and trains, can reduce emissions from personal vehicles

Describe acid deposition.
Acid deposition is an environmental issue that occurs when precipitation is more acidic than normal unpolluted rain, that is, a pH less than 5.6. It can be classified as wet deposition in the case of acid rain or snow, or dry deposition in the case of ash or dry acid substances coming down from the atmosphere and impacting ecosystems.

What is DTM
This model describes the changing levels of fertility and mortality in a human population over time. Birth and death rates shift from high to low levels in a population. The mortality decline precedes fertility decline, resulting in rapid population growth during the transition period.

Fetility and crude birth rate are two demographic variables that can be used to assess human population growth. Explain the streghts and weaknesses of these variables as indicators of growth in human population
Fertility rate and crude birth rate are both useful indicators of population growth but have limitations. Fertility rate is more reliable for predicting long-term growth because it shows the average number of children per woman, but it ignores factors like death rate. Crude birth rate is simple and easy to measure, giving a quick snapshot, but it is affected by age structure, so it may be misleading. Therefore, both should be used together with other data for accurate conclusions.

Explain how two human activities can affect succession in an urban area.
City infrastructure is often made of materials like asphalt that limit succession because plants cannot grow roots into the soil to get minerals and water. We do see, however, that primary succession is quite successful on bricks, cement and wood. Unfortunately, urban pollution limits succession, as acid rain makes the soil too acidic for plants from later stages and tropospheric ozone limits photosynthesis by damaging leaves.

The demographic transition model (DTM) is useful for understanding the effects of social and economic development on the mortality and natality of a country. Outline some of the problems in using the DTM to explain how the population of a country may change.
The DTM was made based on the development of European countries and it may not apply to other cultures with other values. Countries may be able to develop differently now because the medical technologies that were being developed as the countries moved through the stages are now readily available.

Distinguish between the economic impacts of forced and voluntary rural-to-urban migration on urban systems.
While forced migration may lead to low-wage, non-taxable jobs, voluntary migration may fill vacancies for formal jobs with taxable income . Forced migration may add pressure to public services due to a lack of tax contribution, while voluntary migration helps fund these services through taxes.

Distinguish stage 1 and stage 5 in DTM
Stage 1 and Stage 5 of the Demographic Transition Model differ greatly in birth rate, death rate, and population growth. In Stage 1, both birth rate and death rate are high, leading to a stable and low population growth, often due to limited healthcare, poor sanitation, and high infant mortality. In contrast, Stage 5 has very low birth rates and low death rates, but birth rates fall below death rates, resulting in a declining or aging population, often seen in highly developed countries with high living standards and access to healthcare.

Outline two factors that may lead to low birth rates in a HIC (high-income country).
A HIC may experience low birth rates because more women work in paid jobs outside of the house and choose not to have children. Another reason could be the increased awareness about the negative impacts of increasing populations on the environment.

Evaluate whether the issue of acid deposition should be addressed through international cooperation.
A safariOn some occasions, after the primary pollutants SO22 and NOxx are emitted, they precipitate nearby as dry deposition. However, when these primary pollutants are transformed into the secondary pollutants sulfuric acid and nitric acid, they dissolve in water and can precipitate hundreds of kilometres away downwind from the source. For this reason, acid deposition is a regional problem that requires international cooperation to regulate emissions of SO22 and NOx. It is unfair for a country to see its cities, forests and lakes affected by the pollution caused by a neighbouring country.
