What this dot point is asking
This dot point asks you to explain how major global trends affect health and human development, recognising that most trends have both positive and negative implications. You must name the trend, explain the mechanism, and link it to specific health or human development outcomes. The exam often asks you to discuss implications, so balanced answers covering benefits and harms score best.
Climate change
Climate change is one of the most significant threats to global health. Rising temperatures and changing weather bring:
- More frequent extreme events (heatwaves, floods, bushfires, cyclones) causing death, injury and displacement.
- Rising sea levels threatening low-lying nations and homes.
- Changing patterns of infectious disease as mosquitoes spread to new areas, increasing malaria and dengue.
- Reduced food and water security from drought and crop failure, worsening undernutrition.
These effects hit low-income countries hardest, widening global inequality.
Conflict and mass migration
Armed conflict destroys health systems, food supplies, water and infrastructure, and causes death, injury, disability and trauma. It also drives mass migration, with millions displaced as refugees. Migration can strain services and create poor conditions in camps, but it can also bring people to safety and, in receiving countries, can add to the workforce. The health implications include malnutrition, infectious disease, mental ill health and disrupted maternal and child care.
Increased world trade and tourism
Greater world trade and tourism has mixed effects:
- Benefits - access to medicines, technology and a wider range of goods; economic growth that can fund health and education; spread of knowledge and ideas.
- Harms - the global marketing of tobacco, alcohol and energy-dense processed foods drives chronic disease; tourism and trade speed the international spread of infectious disease; some trade can exploit workers or harm the environment.
Digital technologies
The spread of digital technologies, including the internet and mobile phones, has strong implications:
- Benefits - access to health information and education, telehealth reaching remote areas, faster disease surveillance, and connection that supports mental health and social inclusion.
- Harms - a digital divide leaving poorer populations behind, spread of health misinformation, sedentary screen time, and online harms to mental health.
Weighing the implications
Because each trend cuts both ways, strong answers discuss positive and negative implications and note that the impact depends on a country's income and how well the trend is governed. Low-income countries are usually more exposed to the harms and less able to capture the benefits, which is why these trends often widen global inequalities.
In the exam, name the trend, explain a clear mechanism, link it to a health or human development outcome, and where relevant note who is most affected.
Exam-style practice questions
Practice questions written in the style of VCAA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
2025 VCAA7 marksa. Identify one reason why populations might mass migrate. (1 mark)
b. Analyse the implications of mass migration on the health outcomes of those migrating. (6 marks)
Show worked answer →
Part a (1 mark): Any valid push or pull factor, for example fleeing armed conflict or war, escaping persecution, natural disaster or climate change, or seeking work and a better standard of living.
Part b (6 marks): Analyse means examine both negative and positive implications with reasoning. Negatives (about 3 to 4 marks): the migration journey can be dangerous, with exposure to violence, injury, poor sanitation and infectious disease, and limited food and clean water, worsening physical health; the loss of home, separation from family and uncertainty harm mental and social health and wellbeing; on arrival, language barriers, discrimination and unfamiliarity with the health system can reduce access to care. Positives (about 2 marks): migrating away from conflict or poverty to a safer country with better services and employment can improve long-term health outcomes and human development. A high-scoring answer weighs both sides and links to specific health outcomes.
2022 VCAA6 marksWorld tourism has increased significantly over the last 20 years. Analyse the implications of increased tourism for health and wellbeing. (6 marks)Show worked answer →
Six marks: analyse positive and negative implications of increased tourism for health and wellbeing, with reasoning.
Negatives (about 3 marks): increased international travel speeds the spread of infectious diseases across borders (for example influenza and COVID-19), raising morbidity; tourism can damage local environments and cultures and lead to exploitation, harming the social and physical health and wellbeing of host communities.
Positives (about 3 marks): tourism brings income and employment to destination countries, raising living standards and funding services such as healthcare and education, which improves physical, mental and social health and wellbeing; exposure to other cultures can broaden understanding. A strong response presents both sides and connects each to dimensions of health and wellbeing rather than just listing effects.
2023 VCAA6 marksMany Australians use digital health technology to monitor their own health, for example wearing fitness devices, consulting health professionals using telehealth, and accessing pathology results through My Health Record. Using the information above, analyse the implications for health and wellbeing of using digital technologies for knowledge-sharing. (6 marks)
Show worked answer →
Six marks: analyse both benefits and drawbacks of digital technologies for knowledge-sharing, linked to health and wellbeing.
Benefits (about 3 to 4 marks): telehealth and My Health Record improve access to information and care, especially for people in rural and remote areas, allowing earlier diagnosis and better management of conditions, which improves physical health and wellbeing; wearable devices increase awareness and motivation to be active, and easy access to results gives people more control, supporting mental health and wellbeing.
Drawbacks (about 2 to 3 marks): a digital divide means people without devices, internet or digital literacy (often older or lower-income groups) may miss out, widening inequalities; online health information can be inaccurate or cause anxiety, and there are privacy and data-security concerns. Weigh both sides and tie each to health and wellbeing.
