What you will be able to do
identify natural resources; describe dependence, adaptation, or modification; trace one helpful and one harmful possible effect
Resources and Human–Environment Interaction
How do people depend on, adapt to, and change environments?
Activate what you know
Choose one object in the room. Name one natural resource or environmental condition connected to making or using it
- natural resourcesomething from Earth that people use, such as water, soil, sunlight, plants, wind, or minerals
- environmentthe living and nonliving surroundings of a place
- dependto need or rely on
- adaptto adjust actions or designs to conditions
- modifyto change something
- conserveto use and care for resources thoughtfully so they remain available

People and Environments Affect One Another
People depend on environments for water, food, materials, energy, and places to live. They adapt to conditions by changing clothing, schedules, building designs, or transportation. They also modify environments by farming, building, restoring habitat, or creating parks. Calling something a resource describes a human use, but the same water, forest, or soil also supports living systems and may hold cultural meaning. Communities understand and care for places in different ways. Good study asks whose knowledge and needs are included

Careful Choices Use Evidence and Knowledge
Conservation means thoughtful use and care, not simply never using a resource. A community might reduce water waste, protect habitat, repair damaged soil, or choose materials that last. Evidence can show whether the action meets its goal. Local and Indigenous communities may hold detailed knowledge developed through long relationships with a place. That knowledge should be learned from appropriate sources and respected, not copied without permission. Decisions are stronger when scientific evidence, lived knowledge, rights, and long-term effects are considered together
Trace More Than One Effect
An environmental change can help one goal and create another problem. Identify the action, the intended benefit, and effects on people and other living things
Use an Effect Chain
Draw: action - immediate change - effect on people - effect on land, water, plants, or animals. Add a question wherever evidence is missing
Effects Are Often Mixed
Changing an environment is not automatically helpful or harmful. The result depends on the place, purpose, design, who is affected, and what happens over time
Improve a Fictional Schoolyard
Choose one need–shade, water conservation, safer habitat, or access. Propose an action, draw two possible effects, and name one way to check the result
People depend on, adapt to, and modify environments. Responsible choices trace multiple effects, conserve resources, and include evidence, rights, and local knowledge
Practice and answer guide
Work through all 8 questions. Open an answer only after you have written or explained your response.
- 1. Which is a natural resource? A. water B. traffic law C. ballot
Check answer
Water
- 2. Give one example of people depending on an environment
Check answer
Examples include relying on water for drinking, soil and sunlight for food, or local materials for building
- 3. Give one example of adapting to an environmental condition
Check answer
Examples include using shade in a hot climate, insulation in cold weather, raised structures in some flood-prone places, or adjusting schedules to heat
- 4. Draw an action-and-effect chain for one environmental choice
Check answer
Answers vary. The chain must show a real action followed by at least one plausible effect on people or the environment
- 5. Planting streamside vegetation may help in what two ways?
Check answer
Roots can help hold soil, and vegetation can shade water or provide habitat. Results depend on the species and place
- 6. Why should a community check effects over time?
Check answer
Some effects appear slowly, conditions change, and an action may help one goal while causing another problem. Evidence shows whether the plan is working
- 7. Correct this idea: “Conservation means people can never use a natural resource.”
Check answer
Conservation means using and caring for resources thoughtfully, reducing waste or damage, and protecting future availability; it does not always mean no use
- 8. Name one question that should be asked before changing a shared place
Check answer
Acceptable questions include: Who uses or cares for this place? Whose rights are involved? What living things may be affected? What evidence predicts the effects? How will results be checked?
