Ecosystem Services & Human Dependence

MS-LS2-4 · MS-LS2-5 · How do healthy ecosystems support human communities?

Instructions

Driving Question: What happens to human communities when ecosystem services decline?

1. Use sliders to simulate human impacts (deforestation, pollution, urbanization).

2. Click Run to watch ecosystem health change over 50 years.

3. Track how biodiversity, water quality, air quality, and food respond.

4. Try restoring the ecosystem — can you recover lost services?

Key Concepts

Provisioning: food, water, raw materials from ecosystems
Regulating: air/water purification, climate regulation, pollination
Supporting: nutrient cycling, soil formation, biodiversity
Feedback loops: loss of one service cascades to others

Predict

If 50% of forest is removed, which ecosystem service will decline first and fastest? Which will be slowest to recover?

Observe

Run the simulation with high deforestation but high restoration. Does the ecosystem fully recover? How long does it take compared to the damage?

Explain

Why do ecosystem services decline faster than they recover? What does this tell us about the importance of prevention vs. restoration?
