Natural Resources and Their Use — When Nature Becomes a Resource
NCERT Exploring Society: India and Beyond Part-I | India and the World: Land and the People
Opening Thought
We must move toward an economy that works in harmony with nature — repurposing used materials, cutting waste, and replenishing what has been depleted. We must return to the wisdom of nature herself, the greatest regenerator and recycler of all resources.
— Christiana Figueres & Tom Rivett-Carnac, adapted from The Future We Choose
The Big Questions
- How do we categorise natural resources?
- What is the connection between the distribution of natural resources and different aspects of life?
- What are the implications of unsustainable use or overexploitation of natural resources?
When Does Nature Become a Resource?
The word Nature refers to the entirety of living and non-living forms in our environment that exist independently of human creation. When human beings harness these elements for sustenance or transform them into goods for consumption, these natural elements become natural resources?. For instance, a tree standing in a forest is part of the natural environment; when we fell it and fashion its wood into furniture, we treat the tree as a resource.
Definition
Natural Resources: Materials and substances that occur in nature and are valuable to human beings. For something to qualify as a resource, it must be technologically accessible, economically feasible to extract, and culturally acceptable to use.
Not all elements in nature are readily available. Exploitation? of a resource — meaning extraction, utilisation and consumption — is possible only when the technology exists, the cost of obtaining it is reasonable, and its use does not violate cultural norms. For example, petroleum may lie deep below the ocean floor in places we cannot yet reach, or forests may be considered sacred groves that communities choose not to cut.
The Earth holds treasures that have formed over millions of years. Some are obvious — water, air and soil. Others are less apparent — coal, petroleum, precious stones, metal ores and timber.
THINK ABOUT IT
L3 Apply
Pause for a moment. Look at yourself and the objects around you. Where did each of them originate? Trace them back — at some point, every item leads to nature. Even the plastic button on your shirt began as petroleum extracted from deep underground!
Guidance
Consider items like your notebook (trees → paper), the metal in your pen (iron ore → steel), or the glass in a window (sand → silica). This exercise shows that all manufactured goods depend on natural resources as their raw material.
DON'T MISS OUT
L2 Understand
Many indigenous traditions around the world view Nature as sacred. In such cultures, Nature is seen as a nurturer and nourisher rather than merely a storehouse of materials. Indian traditions such as Tulasi puja reflect this reverence — honouring plants as living beings deserving respect.
Reflect: Do you know of practices in your community that reflect this respect for Nature?
Categories of Natural Resources
In science, we learn the usefulness of categorisation? — grouping things by shared characteristics so we can refer to them with a single word or phrase. When these names and meanings are shared across groups of people, it makes communication more effective. We apply the same principle to natural resources.
THINK ABOUT IT
L4 Analyse
What might be the different criteria we could use to group natural resources? Think of at least three different ways.
Guidance
You might classify them by use (life essentials, materials, energy), by renewability (renewable vs non-renewable), by origin (biotic vs abiotic), or by distribution (widespread vs localised).
Categorisation by Use
One helpful way to group natural resources is by the purpose they serve — whether they are essential for life, used as raw materials, or tapped as sources of energy.
Essential for Life
Air, water and food — taken from the atmosphere, rivers and soil. We cannot manufacture the air we breathe or the water we drink.
Resources for Materials
Humans create physical objects from Nature's gifts — wood becomes furniture, marble becomes buildings. India's geographical diversity provides a wide variety, from timber to gold.
Resources for Energy
Electricity for homes, transport and production processes. Energy comes from coal, water, petroleum, natural gas, sunlight and wind.
Renewable vs Non-Renewable Resources
A second important way to classify resources is by whether they can be replenished naturally over time.
Key Concepts
Restoration: Returning something to its original healthy state after degradation or damage. Nature heals — a cut on your skin mends; a forest recovers after a wildfire.Regeneration: Goes beyond restoration — it is Nature's ability to create new life and the conditions for thriving. Planting native trees in a cleared area regenerates the ecosystem.
Nature works in cycles with no waste. When a tree falls in a forest, it decomposes as bacteria, fungi and insects feed on it. The tree enriches the soil, new trees grow from seeds, and eventually some of them will fall too — continuing the cycle indefinitely.
Renewable Resources
Renewable resources? are those that can be restored and regenerated over time. India has abundant sunshine, rivers fed by rain and melting glaciers, forests that renew themselves, and soil that replenishes through natural processes. Solar energy, wind energy, flowing water and timber are renewable — as long as we manage them sustainably.
Critical Condition
For renewable resources to remain available, the natural rhythm of restoration and regeneration must not be disrupted. If we harvest timber faster than the forest can grow new trees, we will eventually deplete the forest entirely.
DON'T MISS OUT
L2 Understand
Traditionally, fishing communities had rules to avoid catching fish during the spawning season so that populations could recover. However, commercial over-fishing has disrupted this balance. Tuna, for example, plays a vital role in maintaining ocean ecosystems by feeding on smaller fish and shrimps. Despite international agreements to control fishing, tuna populations continue to decline.
Think: Do you know of other traditional practices that helped maintain ecological balance?
DON'T MISS OUT — Ecosystem Functions and Services
L2 Understand
Nature has inherent ways of working. Trees produce oxygen; forests filter water and prevent soil erosion. When these natural processes benefit humans, we call them ecosystem services?.
Fascinating fact: A mature tree produces roughly 275 litres of oxygen daily (varying by species). An average human needs about 350 litres of oxygen each day, depending on activity level, height and weight.
Non-Renewable Resources
Non-renewable resources? are formed over extremely long geological periods. They cannot be replenished at the pace we consume them. Fossil fuels such as coal and petroleum, along with minerals and metals like iron, copper and gold, fall into this category. India possesses significant coal reserves, but experts estimate these may last only about 50 more years given the rising demand for electricity driven by population growth and development.
LET'S EXPLORE — Renewable Resources Around You
L4 Analyse
Conduct a small research study to identify the renewable resources in your region. Discuss with your teacher the geographical area of your study and the sources of information you can access.
- What renewable resources are available in your area?
- How has their status changed over time?
- What are the reasons for the change?
- What steps can be taken to reverse any decline?
Prepare a short report with your findings.

List the non-renewable resources you use every day, directly or indirectly. For each one, identify a possible renewable substitute. What steps can your family and community take to transition toward renewables?

L4 Analyse
Identify human actions in your surroundings that result in Nature losing her ability to restore and regenerate. What types of interventions could be undertaken to restore Nature's cycle?

✨ Think & Create
✨
Imagine you are a tree in a forest. Write a short diary entry (4–5 sentences) describing your day — the animals that visit you, the oxygen you produce, and what you fear most about human activities. How would you ask humans to treat you?
Guidance
Think about the ecosystem services a tree provides: oxygen, shade, shelter for birds and squirrels, fruits, and soil binding. Your fears might include logging, pollution, or forest fires caused by humans. End with a hopeful message about how sustainable practices can protect you.
