Key Concepts

6. Key Concepts
A sustainable environment is well-balanced and rich in natural resources. It can fulfill the needs of living organisms while ensuring resources for
future generations.
Carrying Capacity: The environment can support a limited population, known as its carrying capacity. This concept raises questions about
human activities affecting this capacity and potential consequences when ecosystems reach their limit.
Balance Maintenance: It is crucial to maintain balance for life-sustaining environments.
Resource Classification:
• Renewable Resources: These can be regenerated quickly (in one or two human lifetimes), such as air, freshwater, sunlight, plants, and
animals. They are infinite when managed properly.
• Nonrenewable Resources: These resources are finite and cannot be easily regenerated (e.g., fossil fuels like coal, oil, natural gas, and
minerals).

Conservation

8. Conservation
Conservation means preserving and protecting our natural resources while using them wisely. Effective conservation practices include:
Reduce
Minimizing waste production and
consumption of Earth's resources.
Conservation practices can be as simple as turning off lights when not in use, walking or biking instead of driving for short trips, disposing of
waste properly, utilizing energy-efficient appliances, and planting new trees. Consider other methods to contribute to the conservation of Earth’s
resources.
Reuse
Using items again, possibly in different
ways, or after reprocessing.
Recycle
Processing used materials into new,
usable products.

Activity 1: Human Impact on Natural Resources

10. Activities Effects on Natural Resources
When roads are built, mountains are blown off using dynamite. Damage natural habitats and/or kill plants and animals.
Rice fields are turned into residential or commercial centers.
People cut too many trees for lumber and paper, and for building houses.
More factories are built to meet the demands of a fast-growing population and
industrialization.
Too much mining and quarrying for precious metals and stones.
Some farmers use too much chemical fertilizers to replenish soil fertility. Too much fertilizer destroys soil quality and harms both humans and animals.
Plastics and other garbage are burned.
Cars, trucks, and tricycles that emit dark smoke (smoke belchers) are allowed to
travel.
Other activities.
Directions
Identify the effects of human activities on natural resources in your locality based on the table below. Write the observed effects in the second column.

11. Guide Questions
1 Do you know of other activities that destroy or deplete natural resources? Add
them to the list and fill in the corresponding effects in column 2.
2 What can you do to prevent or reduce the effects of the activities listed above?

Activity 2: Developing My Own Recycling Plans

13. Directions
Look around your home and list the items you use. Suggest ways those items can be reused or recycled. Complete the following sentences:
1
I can reuse by ________________.
2
I can recycle by _______________.

Answer Key

15. Activities Effects on Natural Resources
When roads are built, mountains are blown off using dynamite. ➔ Natural habitats are damaged
➔ Plants and animals are killed
Rice fields are turned into residential or commercial centers. ➔ Food resources are reduced.
➔ Excavated areas lead to damage to the water system.
People cut too many trees for lumber or paper or to build houses. ➔ Biodiversity is reduced.
➔ Soil erosion increases.
➔ Reduced food sources.
➔ Fewer plants and animals used as medicine.
More factories are built to meet demands from a fast-growing population and industrialization. ➔ Natural habitats are damaged.
➔ Plants and animals may die or move away.
➔ Reduction in bodies of water and landscape.
Too much mining and quarrying for precious metals and stones. ➔ Destruction of mountain areas.
➔ Damage to natural habitats.
➔ Harm to plants, animals, and miners.
➔ Siltation in rivers may occur.
➔ Risk of cave-ins.
Some farmers use excessive chemical fertilizers to improve soil fertility. ➔ Deterioration of soil quality.
➔ Harm to humans and animals.
Plastics and other garbage are burned. ➔ Contributes to air and water pollution.
