Management of Natural Resources : CBSE Class 10 X Science Video Lectures in English



so the instruments we're about to start over this new chapter and I let me tell you this is a very easy chapter and a very small chapter and you would understand it very very easily strains and basically it is not a chapter of science if you strictly see this is just a chapter to make you aware of our surroundings of our forest of our wild lives and things like that okay friends so the name of the chapter is management of Natural Resources so strains what are the meaning of this word resources what do you mean of the word resources strengths resources of things which are actually useful to us in whatever ways resources are things which are useful to us in whatever ways and natural means natural means provided by nature provided by nature so resources means something useful to us and natural means provided by nature so what is the meaning of this entire term natural resources so natural resources will mean something that is useful to us and has been provided by nature something which is useful to us and has been provided by nature so let me first of all define natural resources natural resources are things provided to us by nature provided to us by whom by whom by nature which can be used to fulfill our needs okay so naturally so there are things provided to us by nature which can be used to fulfill our needs nostrils let us see some examples of natural resources so strains one very good example of natural sources its forests and wildlife forests and wildlife streams they are they have been provided by nature right they have been provided by nature and they're very useful to us very useful to us so they are natural resources for examples how our forests useful for us can you tell me from forest we get wood which is very useful to us from forests we get lot of food products like fruits nuts you know we can eat them that they are very useful to us then from Falls we get a lot of plants from which medicine MIT is can be made that's why for it's a very useful is rules so Follis and wildlife they have been provided to us by nature and they have great use to us so they will be considered Natural Resources Natural Resources something provided by nature and useful to us occasions next example of natural resource can be water response water what is provided to us by nature through reverse lakes ponds and whatever things and they are extremely useful to us because we cannot live without water right we drink water if we don't drink water we cannot live so obviously water is something provided by nature and it's very useful to us so water is another great example of natural resources next very good example of natural resource it's coal and petroleum is true in school and petroleum they have once again provided by nature and they are very useful to us how they are useful to us you know strains these are things which are which are used to provide us energy these are the things which give us energy and on this energy only our automobiles automobiles like cars scooters trucks you know these things run even our industries need coal and petroleum for honey so since these are another things which have been provided by nature and very useful to us so these are examples of natural sources right so one of the examples of natural sources forests and wildlife water : petroleum strains but very sadly strains these natural sources are in danger today these natural resources are in danger today house wins see forests and wildlife they are being destroyed streets false and wildlife are being destroyed trees are being cut as friends right trees are being cut for different different regions will see it and in this chapter wildlife animals are being killed animals are being killed so these forests and wildlife they are in dangerous strains water is also in danger why water is in danger because we are polluting water by dumping waste materials in water right polluting water by dumping waste materials in water these men waste materials are coming from our industries from our houses right and they are polluting water bodies issuance so water is also in danger it is getting polluted coal and petroleum straits we are using excessive use of coal and petroleum excessive use of coal and petroleum straits due to which they're about to finish they about prevention so they are also in danger so since all our natural resources are actually in danger for I send my life we are cutting for it's killing animals for our uses too much water we are polluting it coal and petroleum we are making we are doing excessive use of these things so all these natural sources are in dangerous trains that is why we need to do management of Natural Resources that's why we need to do management of natural sources management of natural sources mean that we need to use these natural resources in a well-defined structured manner right we need to use these natural cells in a very good manner so that they remain protected and we can use them for a very very long time histories that is what we are going to study in this chapter that how we can manage our natural resources nicely right how we can manage our natural shows nicely so that they can last in a proper manner for long long time strands which means we need to manage our natural resources for following reasons for following reasons the first reason is that they are limited they are limited straits so strains let us talk about forests forests are limited forests are limited how are the limitations see if you keep cutting forests like this then one day they will be all over isn't it serious if you keep cutting down trees day by day day by day if you keep cutting down trees what will happen all the forests will be over wanting restraints in that way for its are limited so we need to manage our forests wisely we need to manage our forests wisely otherwise they will be over wanting rights same is the case with coal and petroleum straits : petroleum are also limited but strength you know that we are making excessive use of them in our industries and automobiles right so if we keep doing that one day they will totally over and we will have no coal no petroleum so we need to manage them wisely strains right so there are many natural resources which are limited which are limited and that's why we need to manage them wisely strains then strains there are some natural resources-we which may not be limited which may not be limited for example water what is definitely not limited we have lots and lots of water on the surface of earth but really the problem here is that we are polluting water we are polluting water how we are pollinating by dumping lot of waste into it so we are polluting waters once so if we keep polluting water we will have no clean water to drink isn't it strange so we need to manage our natural resources properly so that we don't pollute them so that we don't pollute them finest prints so the next reason is that we are not we are not using resources in environment friendly way look at this photographs right this is a chimney this is chimney of a factory so in this factory we must be burning coal or petroleum we must be burning coal and petroleum and that's why all this smoke is coming out of the chimney and you see strength this smoke is actually mixing with the environment and polluting it right this smoke from the chimney will pollute the air right so that's why I'm that's what I'm trying to say you that we are not using resources in environment friendly way it is not a good thing because our environment is getting polluted so this is a reason why we need to manage our natural resources wisely because we are not using these resources we are not using these resources in environment friendly way in environment friendly boom next students see natural resources should be equally distributed to all natural resources should be equally this booted – all see-through in snatcher elusive as something which has been provided to us by our nature by our nature right so everybody on this earth everybody on this earth all the human beings all the animals they have equal right on these natural sources because they have been provided by nature so everybody has equal right the cool right on these natural resources but today these natural resources are not equally divided among all some people have more access to natural resources and some have less generally rich people have more access to natural resources and poor do not have which is not a good thing straits because natural resources have been provided by nature so they should be equally available to all right so natural resources should be equally distributed to all so these are some of the regions strains for which we should manage our natural resources in a proper manner what are the reasons they are limited they are delivered in a limited amount we are polluting them we are not using resources in environment friendly manner and lastly natural resources should be equally distributed to our location so you get my points here so now strains we are actually going to talk about forests and void life so we have seen different examples of natural sources and first of all we are going to concentrate on this natural source that is forests and wildlife streets because a very important natural source so strange first of all let's understand this term that is called biodiversity hotspot biodiversity hotspot see shrinks some time forests are called biodiversity hotspot wise friends see in a forest you can find different different type of animals instruments different different type of plants isn't it you can find different different type of animals like snakes Tigers apes you know wolves frogs and so many different different type of animal substrates you can find different different new type of birds different different type of butterflies and insects different of it of plants so shrines you can find different forms of life in forests and that's why Falls are called biodiversity hotspot because you can find different different types of life in forest which means we can write this down so biodiversity means have ability of large number of different living creatures registrants biodiversity means ability of large number of different living creatures as in forests use variety of living creatures like animals plants birds insects actress etc are found in abundance forests are called biodiversity hotspots reference so you understand clearly why forests are called biodiversity hotspots and you also understand what is the meaning of this term biodiversity is an instance now protecting forests means protecting its biodiversity registrants so if we are talking about protecting forests we are actually talking about protecting its biodiversity we're actually talking about protecting its animals we are talking about protecting its boards we are talking about protease insects we are talking about protecting its plants registries so when we are talking about protecting forests we mean protecting its biodiversity registrants protecting the organ immortals in the forest it is necessary to protect biodiversity for stable ecosystem for a stable ecosystem first of all strains look at this term called ecosystem in previous classes and previous chapters we have seen the meaning of this and I'm sure you remember that that what is the meaning of ecosystem so strains if we want to keep ecosystem stable and healthy all these organs need to live all these animals and plants need to leave right difference if any of these animals and if any of these animals or plants are not they in the false then the ecosystem will be disturbed strains for example students I'm sure you must be knowing that these tigers are in great danger to distance then danger they may be extinct from Earth and if they are extinct from Earth they will disturb the ecosystem of the entire forest registrants so it is necessary to protect biodiversity for a stable ecosystem is rights okay so it is necessary to protect different varieties of animals and plants living the forest assurance you understand but who is going to protect forests who is going to protect for assistance are you going to protect false assurance are you going to protect forests I am I going to protect forests friends know struts people like us people like us are not going to predict for us why tell me how many times have you gone to for us a new entire life how many times have you gone to fuss in your entire life maybe two times three times four times maximum for your picnics for your picnics right it's rinse so V people V Norma people go too far is only very often for making a picnics and all so we are other people who are going to protect forests some other people are going to protect forests rinse which means now we'll talk about them people who are going to protect our for us stakeholders historians stakeholders of forests are going to protect our forest friends you must be thinking what is the meaning of this word stakeholders right you must be thinking what is the meaning of this word stakeholders so see strains stakeholders are people with concern or interest in something stakeholders are people or with concern or interest in something so people having concern or interest in forests will be called stakeholders of forest right people having concern and interest in forests will be called stakeholders of for assistance so now let us look at the thing that who are these people who are these people having intestine for us who are these people such friends first such people are people living in and around forests people living in and around forests right these friends is a very simple thing that Pia who are actually living in and around forest would depend on Falls for different different things we'll see that in detail later on but you can really think that if they are a bunch of people who are living in and around forests they will be depending on files for different different things for their livelihood its roots so if they are dependent on forests definitely they will be interested in forests they will definitely be interested in protecting forests right so these are stakeholders or for us these are stakeholders of forests people living in and around for us because they have intestine forests so we call them stakeholders of forest roads then the next stakeholders are businessmen who require forest products for the factories ok so and so who are the next stakeholders of forests businessmen who required forest products for the factories cease fields there are many factories which need forest products for example you can think of furniture factory veterans it will need lot of wood to run registrants so if a businessman is running factories of furnitures then definitely he will have to take interest in forests because his business is running on forests he's any different so businessmen who required forest products for the factories have intestine forests and they are also stakeholders of for assessments right then strains the next stakeholders are Forest Department of government so strange government has made a forest department which is supposed to take care of us so obviously this department has to take interest in for us so this department is a stakeholder of forest restraints you understand the point then finally students we have forest and wildlife activists so strains first of all you need to understand who are these people who are these people forest and wildlife activism so strains these are the people having true love for forests in my life they have true love for forest and Wildlife August Winston so these are the people who want to protect forests and Wildlife just because they love for us in my life they as such they are such have no financial gains from forests they are not being paid for protecting forests and my life they just love forests and my life and that's why they want to protect a distance so these are also stakeholders in for assessments type C strains these people forests and wildlife activists they mainly want to protect big animals like lions tigers elephants so generally these people are more interested in protecting these animals but these people very well know that if they want to protect these animals they have to protect the entire forest they have to protect the entire forest fine sweets so by now we know all the stakeholders of forest who are these stakeholders assurance you must remember first people living in and around force second businessmen who required forest products for their factories third strains Forest Department of government and for the strains forest and wildlife activists so strains now we are going to see that how these stakeholders how these different different type of people actually taking tests in forest and how they help us in protecting our forests okay sprints so let us first of all talk about the first stakeholders friends people living in and around forests people living in and around forests how they use forests so first of all let us see how these people living in and around forest use forests okay so it's they live in and around forest and they use forest for various purposes but how but how so sheron's let's see for wood for burning to get heat in winter and cookie so it spends is a very simple point is rains that they use forest for wood for wooden right as they obtain wood from forest and then they burn it why they bonnet to get Kieran's in winter and also for cooking registrants so this is something which has been going on for ages right for ages right street that people living around forest use wood from forest for burning the wood and by burning the wood they get heat in winter and they also use this heat for cooking instruments right then wood for help in agriculture streets so once again they obtain wood from forests and this would actually help them in agricultural activities then they obtain fruits nuts and medicinal herbs from forest strains then they also take wood from forest to make their hurts to make their heart systems you can see this photograph strains you know these are people living around forests and you can see their hurts that is made up of wood and this wood has been obtained from the forest behind them fine strands then they use forests for grazing cattle so you can see strange this is cattle of these people and you know they are grazing in forest restraints right so these are the different ways in which people living around forests use forest you must remember them what are these ways to obtain wood from forests and they burn the wood to get heat in winter and for cooking then they obtain wood from forest also for help in agriculture the upland fruits nuts and medicinal house from forests they obtain wood from foils to make their hurts and they graze their cattle in forest so now since you must be thinking that these people these people are harming for us or not how are they harming insurance see they are taking wood they are taking wood from forest see they are taking wood for this purpose for this purpose for this purpose right so they're taking lot of wood from forest so they must be cutting a lot of tree insurance so they are destroying our forests right you must be thinking like elephants but that's not true that's not true strange these people do not harm for us these people do not harm for us see they do not cut three strands they do not cut trees they cut only branches of trees very important strains these people these people do not harm for us they do not cut trees they do not cut the complete tree they only cut branches of trees to obtain wood now by doing this they are not harming forests see these people are only cutting branches truants there's no harm in cutting branches because they will grow again they will grow again if you cut the entire tree then it cannot grow again but if you just cut the branches of trees then there's no problem tree is still intact and the branches will again grow which means these people are using lot of wood from forests but they are not harming the forest they are not harming the first you understand see they have been living with forests for centuries for centuries they know how to maintain forests they know how to use forests in a healthy manner so that forest and not harmed so that forest and not harm residence you understand the point see strains in India in India forests have been harmed only after arrival of British us only after available of brittish's see strains Britishers came to India with lot of industrialization with lot of industrialization and with lot of machines and with these machines they started cutting trees harming forests but before braces came via simple people it was simple leave people living with forests in a very healthy manner we had no machines to cut forest but bridge terraces British has brought lot of machines and started coming cutting forests for different different purposes so only after they arrival forest forests were harmed in India before that Falls were intact most of the times
