Management of natural resources refers to the plan of action for renewable and nonrenewable energy sources.
- Natural resource management (NRM) is the management of natural resources such as land, water, soil, plants, and animals, with an emphasis on how management impacts the quality of life for both current and future generations.
- It involves dealing with the interaction of humans and natural landscapes.
- It combines natural heritage management, land use planning, water management, biodiversity protection, and the future sustainability of industries such as agriculture, mining, tourism, fisheries, and forestry.
- It takes into account that people and their livelihoods depend on the health and productivity of our landscapes and that their activities as land stewards play an important role in sustaining this health and production.

Explanation: Waste management is concerned with all types of waste, such as industrial, biological, domestic, municipal, organic, biomedical, and radioactive waste. All of the above mentioned options are the best way to reduce waste.
Ques. Name five commonly used natural resources.
Ans. Natural resources are resources obtained from nature and used with minimal modification. Five common natural resources are water, plants, air, and forests.
Short Answers Questions [2 Marks Questions]
Ques. What is the management of natural resources?
Ans. Natural resource management refers to the action plan for renewable and nonrenewable resources. Global warming, overpopulation, industrial growth, and other factors all have an impact on natural resources such as land, soil, water, plants, and animals.
Ques. Why should we balance natural resources on the planet?
Ans. Natural resources must be managed in order to keep the environment in balance. It prevents the depletion and overuse of natural resources.
Ques. What is meant by renewable energy? Explain with examples.
Ans. Renewable energy is defined as energy produced from natural sources that is replenished at a faster rate than it is consumed. Sunlight and wind are two examples of such constantly replenishing sources. Renewable energy sources are abundant and are all around us.
Ques. What are the various forms of energy?
Ans. The various forms of energy are
- Mechanical energy
- Heat energy
- Light energy
- Sound energy
- Chemical energy and
- Electrical energy.

Ques. What are the methods of natural resource management?
Ans. The methods for managing natural resources are as follows
- Marine and coastal environment protection and enhancement
- Enhancing skills, capacity, and engagement
- Land resource management that is sustainable
- Efficient use of alternative energy sources such as wind and solar energy
- Water asset preservation and enhancement
- Tree planting to reduce soil erosion
- Conserving and recovering biodiversity
- To preserve water in our houses by using appropriate methods
- Before dumping sewage and industrial waste into bodies of water, they must be properly treated.
- Using pipes for transporting oil because oil spills are extremely harmful to aquatic flora and wildlife.
- Rainwater harvesting is another essential practice for water conservation.
Ques. What can you contribute to the production of natural resources?
Ans. Some examples of sustainable practices that contribute to the production of natural resources include
- Encourage the protection and restoration of water sources, as well as the optimization of water usage.
- Proper wastewater treatment implementation.
- Encourage soil protection and increased carbon stores.
- Encourage garbage minimization, recycling, and proper disposal.
- Composting turns food leftovers into valuable nutrients that enhance the soil and improve discharge, reducing soil erosion.
- Plastic single-use is also an essential step towards conservation.
Ques. Why are environmentalists insisting upon 'sustainable natural resource management? Give any three reasons.
Ans. Environmentalists are concerned about "sustainable natural resource management" for the following reasons:
- For equal resource distribution for equal advantages, the majority of natural resources are finite and the human population is rapidly expanding.
- The need for minimizing environmental harm caused by resource over-exploitation and use.
- The requirement to protect resources for future generations.
As a result, careful and planned use of natural resources is essential for sustainable development.
Very Long Answers Questions [5 Marks Questions]
Ques. Why is the management of natural resources important?
Ans. It is essential that we manage the natural resources that we have. The following reasons demonstrate why we must manage our resources.
- Natural resources must be managed in order to keep the environment in balance. All elements of the ecosystem are interconnected. An imbalance induced by excessive use of these resources will disrupt this equilibrium, harming all types of living beings that are directly or indirectly connected to it.
- Managing balanced pressure on many energy sources minimizes overdependence on any one source. Previously, humans relied on coal and petroleum for the majority of their work and technology. However, both of these sources are non-renewable and produce a variety of hazardous compounds and pollutants as byproducts of their use. Recent trends have shifted towards renewable sources such as solar energy and hydro energy, reducing the load on nonrenewable sources.
- Such resources must be made available to future generations. We must not misuse any resource to the point of depletion. We are depriving future generations of such energy sources if we do so.
Ques. Explain the three R's in the conservation of the environment.
Ans. Waste management is essential for maintaining a healthy environment for good growth and survival. One of the most basic methods to help the environment is to follow the three R's formula: Reduce, Reuse, and Recycle.
- Reduce: It means minimizing the use of different resources whenever possible. Avoid food waste, close the tap when not in use, write on both sides of the paper, switch off the light and electrical equipment when not in use, and so on.
- Reuse: The continued usage of things until they become damaged is referred to as reuse. For example, use refillable pens instead of disposable pens, recycle used envelopes, reuse plastic cups and bottles to store various products, and so on.
- Recycle: The process of transforming waste materials into usable forms is known as recycling. For example, paper bags, broken metal utensils, and beverage cartons should be put at recycling centers. Biodegradable wastes should be recycled by creating compost and manure for garden plants.
Ques. Why is reuse considered better than recycling?
Ans. Reusing is preferable to recycling for the following reasons:
- It saves energy since re-manufacturing things involves a significant amount of energy.
- This approach of material repurposing has the potential to significantly minimize waste and pollution.
- It minimizes the demand for additional raw materials, which might lead to a reduction in water and forest supply.
- Recycling is a way of reusing resources that involves the release of garbage or harmful elements that can individually harm the environment.
- Furthermore, recycling plastic is an expensive procedure that exposes employees to a variety of harmful chemicals and compounds. As a result, reuse is preferable to recycling.
