What this topic is asking
Topic 7.8 closes Unit 7 with sustainable development. The College Board wants you to explain the concept (meeting present needs without harming future generations), its environmental, economic, and social dimensions, strategies such as ecotourism and the UN Sustainable Development Goals, and the trade-offs between growth and the environment. The skill is to define sustainable development and weigh the tension between development and sustainability.
The concept and its three dimensions
Sustainable development links progress to the long term.
This framework ties together the measures of development (Topic 7.3), the global economy (Topics 7.6, 7.7), and the environmental consequences of human activity across the course.
The central tension: growth versus environment
Development and sustainability can pull against each other.
This tension echoes the consequences of agriculture (Topic 5.10) and urban sustainability (Topic 6.11): in every case, meeting present needs must be weighed against long-term environmental cost.
Strategies: ecotourism and the development goals
Concrete strategies try to align the dimensions.
- Ecotourism generates income from protecting nature rather than exploiting it, so local communities earn from conservation, aligning economic development with environmental protection. It has limits (it can still strain fragile environments if poorly managed).
- The UN Sustainable Development Goals (SDGs) set global targets across poverty, hunger, health, education, gender equality, clean water, climate, and more, providing a shared framework for sustainable development.
These strategies show how the three dimensions can be pursued together, though trade-offs remain.
Why this matters for the exam
Topic 7.8 is the capstone of Unit 7 and of the course's development theme, drawing together the measures and theories of development (7.3, 7.5), the global economy (7.6, 7.7), and the environmental consequences of agriculture and cities (Units 5 and 6). FRQs ask you to define sustainable development, explain a growth-environment tension, or explain a strategy such as ecotourism, so practice balancing the three dimensions and naming the trade-offs.
Try this
Q1. Identify the three dimensions that sustainable development tries to balance. [Recall]
- Cue. The economic (growth, incomes), the social (equity, health, education), and the environmental (resources, ecosystems, climate); sustainable development requires progress in all three.
Q2. Explain one tension between economic growth and environmental sustainability. [Short explanation]
- Cue. Rapid economic growth usually increases resource use, pollution, and emissions, so raising incomes now can degrade the environment and deplete resources future generations need, forcing a trade-off between present growth and long-term sustainability.
Exam-style practice questions
Practice questions written in the style of College Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AP 2019 (style)1 marksDevelopment that meets the needs of the present without compromising the ability of future generations to meet their own needs is the definition of: (A) comparative advantage. (B) sustainable development. (C) deindustrialization. (D) high mass consumption.Show worked answer →
A stimulus-style multiple choice item. The correct answer is (B).
Sustainable development is development that meets present needs without compromising the ability of future generations to meet theirs, balancing economic, social, and environmental goals. Comparative advantage (A) is a trade concept; deindustrialization (C) is the loss of manufacturing; high mass consumption (D) is Rostow's final stage.
The exam reward is the standard definition of sustainable development as meeting present needs without harming the future.
AP 2021 (style)3 marksSustainable development balances competing goals. (A) Define sustainable development. (B) Explain ONE tension between economic growth and environmental sustainability. (C) Explain how a strategy such as ecotourism is intended to support sustainable development.Show worked answer →
A 3-point define-explain FRQ.
(A) Define (1 point): sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs, balancing economic, social, and environmental dimensions.
(B) Explain (1 point): a tension is that rapid economic growth often increases resource use, pollution, and emissions, so raising incomes can degrade the environment, forcing trade-offs between growth now and sustainability later.
(C) Explain (1 point): ecotourism aims to generate income from protecting nature rather than exploiting it, so local communities earn from conservation, aligning economic development with environmental protection.
Markers reward an accurate definition, a real growth-environment tension, and a clear account of ecotourism.
