Earth, its Protection is our Responsibility

  • 1. RESOURCES & THEIR CONSERVATION Natural Water Mineral Food Land Energy

2. Natural resources Resources that occur naturally and meet the desires of the entireliving beings are known as natural resources. They resources areconsideredvaluable in their relatively unmodified (natural) form. A commodity is generally considered a natural resource when theprimary activities associated with it are extraction and purification, asopposed to creation. All the natural resources come from environment. some of them areessential for our survival while most of them are essential for satisfyingour wants. Today, population explosion and incresase in mans greedy naturehave become the main causes for exploitation of natural resources. 3. Measures to control deforestation Implement afforestationprogrammesOvergrazing of cattle should bereduced Control the usage of paperForest conservation act should bestrictly implemented Recycle and buy recycled products.When a tree is cut,one plant shouldbe grown in order to maintainbalance.Educate people on ecological valueof tree, reduce use of timber, plantProvide alternate fuel to the forestfringe poor people to reducepressure on firewood for daily need. 4. Water resourcesThreats to water resources:Dumping industrial wasteDumping pesticides andorganic wasteEutrophicationBio magnificationThermal pollutionOil spills 5. Measures to conservewater resources Rain water harvesting must be done. Sewage treatment should be implemented. Use drip irrigation for shrubs and trees to applywater directly to the roots where it's needed. Use a water-efficient showerhead. They'reinexpensive, easy to install, and can save you up to750 gallons per month. 6. Look for products bearing the EPAWaterSense Label for items that been certifiedto save 20% or more without sacrificingperformance.Water-saving steam sterilizers, for use inhospitals and health carefacilities.Improved water management practices thatreduce or enhance the beneficial use of water. 7. Mineral resources A 'Mineral Resource' is a concentration oroccurrence of material of intrinsic economicinterest in or on the earth's crust in such form,quality and quantity that there are reasonableprospects for eventual economic extraction 8. Mineral resources are classifies into metallicand non metallic: Metallic:examples are iron,alluminium,copper,gold.etc.. non-metallic: examples are coal,gypsum,silica ,limestone.etc..Threats of mining:Disturbance to mantle layerEarthquakesTsunamiDrowning of landDeforestationAcid mine drainage 9. Conservation methods Implementation of bio-mining/leaching technology. Enhanced oil recovery (eor). Usage of bio fuels. Surface mining control andreclamation act should be strictlyimplemented. Mining activities should me doneunder strict supervision ofauthorities The mined out areas have to beback filled and then rehablitatedfor development of vegetation. 10. Food resourcesFood is any substance consumed to provide nutritional support for thebody. It is usually of plant or animal origin, and contains essentialnutrients, such as carbohydrates, fats, proteins, vitamins, or minerals.The substance is ingested by an organism and assimilated by theorganism's cells in an effort to produce energy, maintain life, orstimulate growth. 11. Conservation of food resourcesImplement the following methods to get chemical freefood:Organic farming:it is a process in which both modernand traditional methods of farming are utilized.Mulching:process of adding or layering dry leavesComposting:conversion of complex materials intosimpler ones with the help of micro organisms.Usage of Green manure. 12. land occupies nearly 20 percentof the earth surface. It coversaround 13000 million hectaresof the area. The houses, roadsand factories occupy nearly onethird of the land. The forestsoccupy another one third ofthe land. The rest of land isused for ploughing and formeadows and pastures. Thesoil forms the surface layer ofland which covers more thanthe 80 percent of land. 13. Conservation of land resourcesMeasures to overcome soil erosion1. Biological control: adapting of some living systems toimprove fertility. they areA. MulchingB. PolycultureC. Crop rotation2. Mechanical control:A. Contour ploughing is a measure to conserve our land.By this method, the fields are ploughed, harrowedand sown along the natural contour of the hills.B. By terracing method: A series of wide steps are madealong the slop following the contours. This method isvery common in rice growing regions. 14. 3. By educating, informing and sensitizing all landholdersabout various aspects of this precious resources andtheir sustainable use4. Under the afforestation and reforestationprogrammes, planting of trees, bushes and grass help tocheck the soil erosion.5. Strict actions are taken to check reckless felling oftrees and overgrazing.6. Shelter belts (rows of trees) are planted on themargins of desert areas to check the fury of wind.7. Construction of dams and gully-trap inculcate thewater-harvesting. 15. Energy resourcesEnergy is the capacity to do work and is requiredfor life processes. An energy resource is somethingthat can produce heat, power life, move objects, orproduce electricity.Matter that stores energy is called a fuel. 16. Energy resources are classified into two types.They are:Renewable: solar energy, wind energy,tidal energy, geothermal energy etc..Non renewable energy: coal, Petrol, diesel.etc.. 17. CFLs use 60% less energy than a regular bulb. Thissimple switch will save about 300 pounds ofcarbon dioxide a year. Change your travel behaviour, think more interms of public transportation, if possible, walk orride your bicycle instead of taking the car. Turn off lights and appliances when you are notusing them, use energy-saving light bulbs. Use a microwave instead of a stove to reheatfood. 18. Presented by :MANSOURI Ayoub 19. Definition of pollution Pollution is the introduction ofcontaminants into a natural environmentthat causes instability, disorder, harmor discomfort to the ecosystem . Pollution can take the form of chemicalsubstances or energy such as noise,heat or light. 20. Air pollution : DefinitionAir pollution is theintroduction ofchemicals, particulatematter, or biologicalmaterials that causeharm or discomfort tohumans or other livingorganisms, or damagesthe natural environmentinto the atmosphere. 21. Air pollution : Causes- Industries.-Automobiles and Domestic fuels-Fire-High Proportion of undesirablegases, such as sulphur dioxide andcarbon monoxide 22. Air pollution : Effects Human health Animals Plants The atmosphere as a whole Acid rain 23. How to prevent air pollution ? Carpool Walk or ride a bicycle Connect your outdoorlights to a timer or usesolar lighting. Wash clothes with warmor cold water instead ofhot. Plant trees etc. 24. Water pollution : DefinitionWater pollution is thecontamination of water bodies(e.g. lakes, rivers, oceans,aquifers and groundwater).Water pollution occurs whenpollutants are directly orindirectly discharged intowater bodies without adequatetreatment to remove harmfulcompounds 25. Water pollution : Causes Marine Dumping Industrial Waste Sewage, mainly fromhouseholds Nuclear waste Oil pollution Underground storageleaks 26. Water pollution : Effects Diseases like Cholera Malaria Typhoid (spread duringthe rainy season ) Aquatic life getsdestroyed 27. Water pollution : Solutions Turn off running water Fertilize correctly Organize or participatein a clean up Join a special societydevoted to theprevention of waterpollution 28. Noise pollution : DefinitionNoise pollution isdispleasing human,animal or machine-createdsound thatdisrupts the activity orbalance of human oranimal life. 29. Noise pollution : Causes Traffic Noise Air craft Noise Noise from constructionand civil engineeringworks. Noise from theIndustries. Noise from other sources. 30. Noise pollution : Effects Hearing Loss High Blood Pressure Stress Sleep Disturbance Colour Blindness 31. How to prevent noise pollution 32. LAND POLLUTIONLand pollution is thedestruction of Earth'sland surfaces throughmisuse of land resourcesby human activities.Polluted land has depositsof liquid and solid wastesuch as rubbish, garbage,paper, glass and plasticobjects. 33. Land pollution : Causes Accidental Spills Industrial Accidents Landfill and illegal dumping Agricultural practices Mining and other industries Oil and fuel dumping Buried wastes Drainage of contaminatedsurface water into the soil Electronic waste 34. Contaminated lands and environments can: Cause problems in the human respiratory system. Cause problems on the skin. Cause various kinds of cancers.The toxic materials that pollute the soil can get into thehuman body directly by: into contact with the skin. washed into water sources like reservoirs and rivers. Eating fruits and vegetables that have been grown inpolluted soil. Breathing in polluted dust or particles. 35. How to prevent land pollution More and more land should bebrought under farming. Trees should be plantedeverywhere. Waste matter should bedisposed immediately Avoid drilling lands forunderground water. Avoid using fertilizer andpesticides for farming. 36. Despite the Advantage of nuclear as a cleanenergy, the big concern is the resulted fromnuclear reaction, which is a form of pollutioncalled Radio activity.Radiation (Laser-Rays) will from Radio ActivePollution. 37. Nuclear powerplants(Ex:Neyveli,Kalpakkam) Nuclear Weapon(Ex:Missiles) Disposal of Nuclear Waste Uranium Mining 38. Radio Active Pollution : Effects The Diseases include bloodin cough Ulcer Swelling of bone joints Cancer Lung Cancer Skin Cancer Bone Cancer Eye Problems 39. How to Prevent of Radio ActivePollution Avoid Constructing Nuclear Power Plants Avoid Using Nuclear Weapon Have Proper Treatment for NuclearWaste Avoid mining for Uranium to a minimal 40.
