Global Issues and Sustainability — High School World Geography practice questions

The UN Sustainable Development Goals (SDGs), adopted in 2015, set targets for:

1. A single environmental goal on climate change
2. Seventeen interconnected goals covering poverty, health, education, gender, environment, and more, to be achieved by 2030
3. Only ending hunger
4. Only providing internet access to all people

Answer: B — Seventeen interconnected goals covering poverty, health, education, gender, environment, and more, to be achieved by 2030

17 SDGs across social, economic, and environmental dimensions replaced the earlier MDGs. A/C/D narrow the framework misleadingly.

Which of the following is the best example of the 'energy transition' underway in many countries?

1. Shifting electricity generation from coal and oil toward solar, wind, hydro, and nuclear (low-carbon sources)
2. Moving from renewable to fossil-fuel sources to increase reliability
3. Shutting down all forms of electricity generation to reduce emissions
4. Replacing electricity with animal power

Answer: A — Shifting electricity generation from coal and oil toward solar, wind, hydro, and nuclear (low-carbon sources)

Energy transition = decarbonization of energy supply. B reverses the direction; C confuses conservation with elimination.

A 'megacity' is generally defined as an urban agglomeration with a population of at least:

1. 100,000
2. 10 million
3. 1 million
4. 100 million

Answer: B — 10 million

UN convention: megacity ≥ 10 million. C is the threshold for a 'large city,' not megacity — off-by-a-factor-of-ten trap.

The greenhouse effect refers to:

1. Sunlight being blocked by clouds
2. Certain atmospheric gases absorbing and re-emitting infrared radiation, warming Earth's surface
3. Ozone depletion in the stratosphere
4. Volcanic ash cooling the atmosphere

Answer: B — Certain atmospheric gases absorbing and re-emitting infrared radiation, warming Earth's surface

Greenhouse gases (CO2, CH4, H2O vapor, N2O) trap outgoing IR. C confuses greenhouse effect with the ozone hole — a distinct atmospheric issue.

The 2015 Paris Agreement is an international framework aimed at:

1. Banning nuclear weapons
2. Limiting global average warming to well below 2°C above pre-industrial levels (pursuing 1.5°C)
3. Regulating international trade tariffs
4. Protecting cultural heritage sites

Answer: B — Limiting global average warming to well below 2°C above pre-industrial levels (pursuing 1.5°C)

Paris Agreement = climate treaty with nationally determined contributions. A confuses it with the NPT; C with WTO agreements — classic mission mix-ups.

Rising atmospheric CO₂ is a CAUSE, and warming global temperatures are the EFFECT. Which statement correctly reflects this direction of causation in modern climate change?

1. Warmer temperatures raise CO₂ concentrations, which is the main driver of recent climate change
2. Volcanoes emit more CO₂ than human activity, which drives temperature
3. CO₂ has no measurable effect on planetary temperature
4. Human emissions of CO₂ and other greenhouse gases enhance the greenhouse effect, warming the surface

Answer: D — Human emissions of CO₂ and other greenhouse gases enhance the greenhouse effect, warming the surface

Direction-reversal trap: A flips cause and effect (feedbacks exist, but anthropogenic CO₂ is the driver of the modern trend). B misstates the volcano-vs-humans magnitude (humans emit ~100× more CO₂ per year than volcanoes).

The Amazon and the Congo are the world's two largest tropical rainforests. A key difference in the drivers of deforestation is that:

1. Amazon deforestation is mainly from oil drilling; Congo deforestation is mainly from mining
2. Both are driven overwhelmingly by urban sprawl from megacities inside the forest
3. Both are protected by international law and are not being deforested
4. Amazon loss is driven heavily by cattle ranching and soy expansion; Congo Basin loss is driven more by small-scale/subsistence agriculture and fuelwood, with growing industrial logging

Answer: D — Amazon loss is driven heavily by cattle ranching and soy expansion; Congo Basin loss is driven more by small-scale/subsistence agriculture and fuelwood, with growing industrial logging

Empirical driver studies show the Amazon has industrial-scale agribusiness pressure, while the Congo Basin's losses have historically been more subsistence-driven. C reverses reality; A misstates the sectors.

'Food security' means:

1. Having a large national army to protect farms
2. Reliable access by all people to sufficient, safe, and nutritious food to meet dietary needs
3. Growing only genetically modified crops
4. Exporting more food than a country imports

Answer: B — Reliable access by all people to sufficient, safe, and nutritious food to meet dietary needs

FAO's canonical definition. A is a play on the word 'security'; D confuses food security with a positive trade balance in food.

The Intergovernmental Panel on Climate Change (IPCC) is best described as:

1. A UN agency that sets binding emissions limits on countries
2. A private industry lobbying group
3. A UN-affiliated scientific body that assesses published climate science and publishes periodic assessment reports
4. A treaty enforcement court for climate violations

Answer: C — A UN-affiliated scientific body that assesses published climate science and publishes periodic assessment reports

The IPCC synthesizes existing peer-reviewed research; it does not set policy or enforce rules. A is a common confusion with the UNFCCC/Paris Agreement process — the classic trap.
