Environment, Resources, and Sustainability
People depend on the natural world for food, water, energy, and materials — but those resources are not unlimited. The relationship between human societies and the environment, and the challenge of sustainability, is a growing part of the test.
Natural resources are materials from the earth that people use, like water, soil, forests, and fuels. Sustainability means using those resources in a way that meets today’s needs without using them all up for future generations.
Renewable and Nonrenewable Resources
Resources come in two types. Renewable resources are replaced by nature about as fast as we use them — sunlight, wind, water, and forests (if replanted). Nonrenewable resources exist in limited amounts and cannot be replaced on a human timescale — fossil fuels like coal, oil, and natural gas, plus minerals and metals. Because nonrenewable resources run out and often pollute when used, societies increasingly look to renewable sources like solar and wind power.
Humans and the Environment
People change the environment to meet their needs — clearing forests for farms, building cities, mining, and burning fuels. These activities bring benefits but also costs: pollution, loss of habitat, and climate change from greenhouse gases released by burning fossil fuels. Geography studies this two-way relationship: the environment shapes how people live, and people reshape the environment.
Sustainability and Conservation
Sustainability is about balance — using resources without destroying the ability to use them in the future. Conservation means protecting resources and using them wisely: recycling, reducing waste, protecting forests and water, and shifting to renewable energy. On the test, the “sustainable” choice is usually the one that meets current needs while preserving resources for the future, rather than using everything up now.

A Routine for Environment Questions
- Renewable resources refill naturally (sun, wind, water); nonrenewable ones run out (fossil fuels).
- Human activity brings benefits but also pollution and climate change.
- Sustainability = meeting today’s needs without using up resources for the future.
- Conservation protects resources through wise use and renewable energy.
Practice
- What is a natural resource?
- Name one renewable resource.
- Are fossil fuels renewable or nonrenewable?
- Name one negative effect of burning fossil fuels.
- What does sustainability mean?
- Give one example of conservation.
Answers
- A material from the earth that people use.
- Any of: sunlight, wind, water, forests.
- Nonrenewable.
- Any of: pollution or climate change.
- Using resources without using them all up for future generations.
- Any of: recycling, reducing waste, protecting forests, using renewable energy.

This connects geography to economics, building on the idea of scarce resources and linking to how population and settlement affect the land. See every topic on the Social Studies Prep Hub.
