Natural Resources Used by Humans
Issue — What natural resources do humans use and why must they be managed responsibly?
- Understand what a natural resource is.
- Identify different natural resources used by humans.
- Distinguish between renewable and non-renewable resources.
- Understand that resource exploitation can change landscapes and habitats.
Part 1: Understanding What a Natural Resource Is
A natural resource is an element found in nature that humans use to meet their needs, for example to feed themselves, have shelter, keep warm, travel, or make objects.
Humans have long used elements from their environment. They collect water, wood, rocks, metals, arable soils, and energy sources.
These natural resources are essential for everyday life. They enable the building of houses, producing electricity, making tools, growing food, or traveling.
To construct a building, one can use sand, gravel, limestone, water, wood, and metals. These materials come directly or indirectly from natural resources.
Main Categories of Natural Resources
| Resource Category | Examples | Main Uses |
|---|---|---|
| Water | Rivers, groundwater, lakes. | Drinking, washing, irrigation, energy production. |
| Rocks and materials | Limestone, granite, sand, clay. | Building, making cement, producing bricks or glass. |
| Ores | Iron ore, copper, aluminum. | Making tools, cables, vehicles, everyday objects. |
| Energy resources | Oil, gas, coal, wind, sun, moving water. | Energy production, heating, transportation. |
| Soils | Agricultural lands, forest soils. | Growing food, cultivating plants, producing wood. |
A natural resource is an element of nature used by humans to meet their needs. Water, rocks, ores, soils, wood and energy sources are important natural resources. They allow building, feeding ourselves, producing energy, and manufacturing many objects.
Part 2: Renewable and Non-Renewable Resources
Not all natural resources renew at the same rate. Some can regenerate quickly within a human lifetime, while others take millions of years to form.
A renewable resource is a natural resource that can naturally replenish in a relatively short time if used responsibly.
A non-renewable resource is a natural resource that forms very slowly, often over millions of years. At a human scale, it can be depleted.
Examples of Renewable Resources
Renewable resources can be used sustainably if their extraction does not exceed their renewal capacity. For example, a forest can provide wood if trees are replanted and young trees are allowed to grow.
- Wood, if forests are properly managed.
- Water, if it is not wasted or polluted.
- Solar energy, generated from sunlight.
- Wind energy, produced thanks to wind.
- Hydraulic energy, produced from moving water.
Examples of Non-Renewable Resources
Non-renewable resources exist in limited quantities. Once extracted and used, they do not replenish quickly enough to be replaced in a human lifetime.
| Resource Type | Examples | Why It Is Limited |
|---|---|---|
| Fossil fuels | Oil, coal, natural gas. | They form over millions of years from ancient organic matter. |
| Metallic ores | Iron, copper, aluminum, zinc. | Extractable deposits exist in limited amounts. |
| Certain rock materials | Sand, aggregates, building stones. | They may be extracted faster than natural formation or local availability. |
Oil is a non-renewable resource. It formed very slowly underground from the remains of ancient living organisms. When used as fuel or to make certain objects, it does not replenish quickly.
Natural resources can be renewable or non-renewable. A renewable resource can naturally replenish if used carefully. A non-renewable resource forms very slowly and can be exhausted. Wood, wind, sun, and water can be renewable, while oil, coal, natural gas, and many ores are non-renewable.
Part 3: Extracting and Using Natural Resources
Before use, many natural resources must be collected, extracted, transported, and sometimes transformed. These steps require energy, equipment, and infrastructure.
Resource exploitation refers to all actions that allow collecting, extracting, transforming, and using a natural resource.
Resources Extracted from Underground
Some resources are extracted from mines or quarries. A mine extracts ores or fuels like coal. A quarry often extracts rocks or construction materials.
Limestone can be extracted from a quarry. It can then be used as a building stone or to produce cement.
Resources Processed Before Use
Many natural resources are not used directly in their original form. They are transformed to make materials, objects, or energy.
| Natural Resource | Possible Transformation | Product or Use |
|---|---|---|
| Iron ore | Extraction then factory processing. | Steel for buildings, tools, vehicles. |
| Sand | High-temperature heating with other materials. | Glass for windows, bottles, screens. |
| Clay | Shaping then firing. | Bricks, tiles, pottery. |
| Oil | Refining and chemical processing. | Fuels, plastics, some synthetic textiles. |
| Wood | Cutting, drying, assembly, or processing. | Furniture, paper, frameworks, heating. |
These transformations show that everyday objects often have a natural origin. A phone, a bike, a house, or a notebook require several different natural resources.
To be used, natural resources often need to be extracted, transported, and transformed. Mines, quarries, exploited forests, dams, or fields are places where humans collect resources. Everyday objects often come from multiple transformed natural resources.
Part 4: Consequences of Resource Exploitation
The use of natural resources is necessary for human societies, but their exploitation can affect landscapes, living beings, water, air, and soils.
An environmental impact is a positive or negative consequence of a human activity on the environment.
Altered Landscapes
Extraction of rocks, sand, ores, or fuels can change landscapes. A quarry can dig into a hill, a mine can alter underground layers, and a dam can modify a river's course.
A limestone quarry provides materials useful for building but changes the landscape and can destroy habitats for some species.
Disrupted Habitats
When an environment is altered, living beings may lose their food, shelter, or living conditions. Pollution can also make some habitats less suitable for life.
| Human Activity | Resource Concerned | Possible Consequence |
|---|---|---|
| Quarry extraction | Rocks, sand, aggregates. | Landscape change and possible habitat destruction. |
| Mining | Ores, coal. | Possible pollution and underground alteration. |
| Deforestation | Wood, agricultural soils. | Habitat loss and reduced biodiversity. |
| Excessive water withdrawal | Freshwater. | Lower river levels or groundwater tables. |
| Burning oil, gas, or coal | Fossil energies. | Gas emissions and air pollution. |
Sometimes Wasted Resources
A resource is wasted when it is used unnecessarily or when a large part is thrown away but could be reused, repaired, or recycled. Waste increases extraction from nature.
Exploiting natural resources can change landscapes and disrupt habitats. It can also cause pollution or depletion of some resources. Natural resources are essential, but their use must consider environmental consequences.
Part 5: Using Resources Responsibly
To preserve natural resources, it is important to use them better. This doesn't mean stopping all use but avoiding waste, limiting pollution, and choosing more sustainable solutions when possible.
Sustainable use of resources means meeting current needs while preserving resources and habitats for future generations.
Simple Actions to Save Resources
- Save water by avoiding unnecessary running taps.
- Repair objects when possible instead of throwing them away quickly.
- Reuse some objects or materials.
- Sort waste to enable recycling.
- Limit food waste.
- Choose strong and useful items rather than quickly discarded ones.
Recycling means recovering materials from waste to make new objects or materials.
Recycling an aluminum can recovers already extracted metal, reducing the need to extract new ores and cutting down waste.
The Role of Collective Choices
Individual actions are helpful, but resource management also depends on collective decisions: protecting natural areas, limiting pollution, organizing recycling, developing cleaner energy, or restoring habitats after exploitation.
| Responsible Action | Objective | Concrete Example |
|---|---|---|
| Reduce | Use fewer resources. | Avoid wasting water, energy, or food. |
| Reuse | Extend an object's lifespan. | Use a box, bag, or piece of clothing multiple times. |
| Repair | Avoid throwing away usable objects. | Fix a bike, furniture, or device when possible. |
| Recycle | Recover materials. | Recycle glass, paper, metal, or some plastics. |
Using resources responsibly helps limit waste, pollution, and resource depletion. Simple actions like saving water, repairing, reusing, and recycling can help. Collective choices are also essential to better manage natural resources and protect habitats.
Natural resources are elements found in nature that humans use to live, build, produce energy, travel, or make objects. They can be renewable, like wood, water, wind, or the sun, if used responsibly; or non-renewable, like oil, coal, natural gas, and many ores. To use these resources, humans often extract, transport, and transform them. This exploitation can change landscapes, disrupt habitats, cause pollution, or deplete some resources. To protect the environment and available resources, they must be used responsibly: reducing waste, repairing, reusing, recycling, and choosing more sustainable solutions.
