Question 1
Overuse faster than natural renewal can deplete a resource. Reduce use, protect and restore it, and allow recovery time.
Use renewable resources at a rate nature can replace them.
Question 2
List five functions such as oxygen production, water filtering, pollination, climate regulation and nutrient recycling.
Ecosystems perform natural processes that support human life.
Question 3
Renewable: nature can restore it over time. Non-renewable: it forms too slowly to replace what we use. Protect and manage renewables.
Examples: sunlight and sustainably managed forests; coal and petroleum are non-renewable.
Question 4
Write observed local habits that save, reuse or protect water, energy, food, soil, trees or other resources.
Personal examples will vary by home and neighbourhood.
Question 5
Consider resource sources, effects on people and ecosystems, water and energy use, pollution, waste and product durability.
Produce goods in ways that reduce harm and conserve resources for the future.
