Natural resources are materials and components of nature that humans use to satisfy their needs. They include resources such as water, soil, forests, minerals, sunlight, and fossil fuels. However, not everything found in nature is considered a resource.
A natural material becomes a resource only when it is useful, technology is available to use it, and its use is economically viable.
They are found in nature.
They are essential for meeting human needs.
They support agriculture, industries, transportation, and daily life.
Natural resources can be classified into different categories based on their characteristics. One common classification is according to their origin, which helps us understand where these resources come from and how they are formed.
Natural resources are classified based on their origin into two categories: biotic and abiotic resources. This classification helps us understand whether a resource comes from living organisms or from the non-living components of nature.
|
Resource Type |
Description |
Examples |
|
Biotic Resources |
Biotic resources are obtained from living organisms. |
Forests, Wildlife, Fisheries, Livestock |
|
Abiotic Resources |
Abiotic resources come from non-living components of nature. |
Air, Water, Minerals, Sunlight |
Natural resources can also be classified based on their ability to replenish over time. Depending on how quickly they are naturally replaced, they are grouped into renewable and non-renewable resources.
|
Resource Type |
Description |
Examples |
|
Renewable Resources |
Renewable resources can be replenished naturally within a short period. |
Solar energy, Wind energy, Water, Forests (when managed properly) |
|
Non-Renewable Resources |
Non-renewable resources take millions of years to form and cannot be replaced quickly once exhausted. |
Coal, Petroleum, Natural gas, Minerals |
Natural resources are important because they:
Provide food and water.
Supply raw materials for industries.
Meet energy requirements.
Support agriculture.
Help maintain ecological balance.
Sustainable development refers to meeting present needs without affecting the ability of future generations to meet their own needs.
Use resources responsibly.
Reduce wastage.
Protect biodiversity.
Encourage renewable sources of energy.
Maintain environmental balance.
Conservation means protecting and using natural resources wisely. It helps reduce resource depletion, protects the environment, and ensures that natural resources remain available for future generations.

Conservation Method |
Ways to Conserve |
|
Forest Conservation |
Prevent unnecessary cutting of trees. Promote afforestation and reforestation. Protect wildlife habitats. |
|
Water Conservation |
Practice rainwater harvesting. Use water efficiently. Prevent water pollution. |
|
Soil Conservation |
Reduce soil erosion. Encourage proper farming practices. Maintain vegetation cover. |
|
Energy Conservation |
Save electricity. Use energy-efficient appliances. Promote renewable energy sources. |
Improper use of natural resources can create several environmental problems.
Deforestation
Soil degradation
Water pollution
Air pollution
Loss of biodiversity
Climate change
These issues highlight the need for responsible resource management.
Every individual can contribute to conserving natural resources by:
Saving water and electricity.
Planting trees.
Reducing waste.
Recycling reusable materials.
Using natural resources responsibly.
The following points highlight the most important concepts from the chapter. Reviewing these key points can help you quickly revise the topic before your examination.
Natural resources are obtained from nature.
They are classified as biotic and abiotic resources.
They are also classified as renewable and non-renewable resources.
Sustainable development promotes responsible use of resources.
Conservation helps protect resources for future generations.
Forest, water, soil, and energy conservation are essential.
