NCERT Class 10 Physics Chapter 16 Notes
Natural Resources:-
Natural resources are resources that occur naturally and can exist without human intervention.
Soil, water, coal, petroleum, natural gas, and forests are only a few examples.
Protecting The Natural Resources:-
The Ganga Action Plan is a programme that aims to improve the Ganga's water quality.
Human activities such as bathing, washing, and industrial effluents, as well as disease-causing microbes, polluted the Ganga.
Coliform bacteria are a type of bacterium prevalent in the human intestine, and their presence in water signals that disease-causing microbes have contaminated it.
Some pollutants are dangerous even in small amounts, necessitating the use of complex measures to keep them in check.
The use of a universal indicator to check the pH of water is a technique that can be checked.
To save the environment, three R's are used — reduce, reuse, and recycle.
Reduce the number of natural resources used - natural resources should be used in smaller amounts.
Recycleable garbage, such as plastic, glass, and metal, can be collected separately and repurposed to create new objects.
Things should be reused as much as possible.
Pickle-filled plastic bottles, for example, can be reused for other purposes.
Need for managing natural resources
The things that are used, like as roads, houses, and clothing, as well as the items that are consumed, such as food and beverages, are derived from the earth's natural resources.
Natural resources are limited, and as the human population grows, so does the demand for natural resources.
Natural resource pollution causes environmental damage.
For example, a considerable amount of slag is wasted after mining, resulting in pollution.
Natural resources should also be managed to guarantee that they are distributed fairly to all.
Wildlife and Forests
Forests are referred to as "biodiversity hotspots."
Biodiversity refers to the variety of organisms that live in various ecosystems.
Because a loss of biodiversity can lead to a loss of ecological stability, biodiversity should be protected.
All species, as well as stakeholder groups, are heavily reliant on the forest.
Stakeholders Include-
local people who live in or near forests and rely on them for firewood, timber, fruits, nuts, medicines, and thatch for homes, baskets for collecting food, fishing equipment, and cultivation.
The forest department, which controls the property, turned the forests to monocultures of pine and teak plants, clearing vast amounts of vegetation in the process, affecting a considerable amount of biodiversity as well as the diverse needs of the local people.
Forests are used by manufacturers as a source of raw materials for their enterprises.
Nature lovers desire to preserve nature in its natural state.
Forests should be managed in a way that is both environmentally and economically beneficial.
Water
All terrestrial life forms require water to survive.
Water availability in many locations is also affected by human involvement.
Because of urban waste, diversion for high-water-demanding crops, and other factors, water supply is decreasing.
Locals use irrigation systems such as dams, tanks, and canals to provide the bare minimum of agricultural and daily needs.
Dams can be used to store water not just for agriculture but also for electrical generation.
Dam-fed canal systems can transport vast amounts of water across long distances.
The Indira Gandhi canal, for example, has delivered greenery to wide swaths of Rajasthan.
Large dams are being built despite opposition.
Many peasants and tribal people are displaced without proper compensation to build dams, causing social difficulties.
Economic troubles arise as a result of the public spending significant sums of money without receiving any gain.
Water Harvesting
Conservation of water boosts biomass production.
Water harvesting aims to develop fundamental resources such as land and water in order to generate secondary resources.
Water harvesting structures in relatively level terrain include crescent-shaped earthen embankments and straight concrete and rubble check dams built across seasonally flooded gullies.
The following are some of the benefits of storing water in the ground:
It doesn't go away.
Spreads out to replenish wells and deliver moisture to vegetation across a large area.
Mosquitoes will not be able to breed in this area.
Human and animal waste are kept at bay.
Coal and Petroleum
Coal, petroleum, and fossil fuels are all essential sources of energy.
Coal and petroleum were produced millions of years ago as biomass was degraded.
Carbon, hydrogen, oxygen, and sulphur are all present.
Carbon dioxide, nitrogen oxides, and sulphur oxides are produced when coal and petroleum are burned.
Carbon monoxide is generated instead of carbon dioxide when combustion occurs insufficient air.
At high concentrations, sulphur, nitrogen, and carbon monoxide oxides are toxic.
A greenhouse gas is carbon dioxide.
Because coal and petroleum contain significant amounts of carbon, converting all of this carbon to carbon dioxide can result in severe global warming, natural resources should be managed wisely.

Frequently Asked Questions (FAQs)
1. What are natural resources according to Class 10 Sustainable Management of Natural Resources notes?
Natural resources:-
Natural resources are resources that occur naturally and can exist without human intervention.
Soil, water, coal, petroleum, natural gas, and forests are only a few examples.
2. What is the definition of water harvesting? Any two water harvesting structures should be mentioned?
Water harvesting is the process of collecting rainwater as it falls or runoffs in a local region for future use.
Khadins in Rajasthan and Kulhs in Himachal Pradesh are two water-gathering structures.
3. Make a list of four benefits of water harvesting.
The following are some of the advantages of water harvesting:
It serves as a water source.
It is a source of irrigation water.
It is to blame for the rising groundwater level.
It lowers stormwater runoff, urban flooding, and sewage treatment plant overflow.
4. What exactly does the term "wildlife" imply? What role does wildlife play in our lives?
All naturally existing animals, plants, and their species that are not grown, domesticated, or tamed are considered wildlife.
Because wildlife is essential to us as:-
They have a lot of aesthetic value for people.
They contribute to the preservation of ecological balance.
5. What exactly is a dam? Write two major benefits and two major drawbacks of building a large dam
Dams are huge barriers built across rivers and streams to contain and use water for human purposes such as agriculture and electricity generation.
The following are two major advantages of building a large dam:
Electricity production.
Irrigation.
The following are two negative consequences of building a large dam:
It causes a big number of individuals to be displaced.
It results in deforestation and biodiversity loss.
