It isexpectedthatyouwill read,studyandwill seriouslyanswerall the guide questionsandactivitiesstipulated inthis
module andsubmititonthe agreeddate.
II.LearningObjectives
A. Define termsrelatedtolandpollution
B. Enumerate sourcesof landpollution
C. Elaborate effective waysof RecyclingandReducingNon-biodegradableandBiodegradable
Waste
III.LearningExperience
PresentationandDiscussion
A. Basic Termsto Study
Oneof the waysthatwill help you understand and masteraboutthetopicis
to get oriented or familiarizethe common termsused in this module.This will also
help you enrich yourvocabulary.Pleasestudy thefollowing terms:
 Land Pollution- referstothe deteriorationof the earth'sland surfaces,atand below groundlevel.
 Garbology- the studyof a communityorculture byanalyzingitswaste.
 Garbage- unwantedmaterialsandobjectsthatpeople have thrownaway

2.  SolidWaste- anyunwantedproductwhichisnota liquidorgas inour surroundingsandfromour dailyproducts
 Disposal- the actionorprocessof throwingawayor gettingridof something.
 Recycling- the actionor processof convertingwaste intoreusablematerial.
 Reducing- the processof makingsomethingsmallerinsize orinamount.
 Non-biodegradable Wastes - are those whocannotbe decomposedordissolvedbynatural agents.Theyremain
on earthfor thousandsof yearswithoutanydegradation
 Biodegradable Wastes- includesanyorganicmatterin wastewhichcan be brokendownintocarbondioxide,
water,methane orsimple organicmolecules
 Reusing– processof using somethingagain.Usingmore thanonce.
 Repairing–process of fixingsomething
 Replacing– processof findinganalternative of somethingbetterthanthe usual thing
Thoseare the basic termsrelated to this moduleand I wantyou to study and read thewhole moduleand getoriented
with thoseterms.
B. Land Pollution:Causes,Effectsand Remedies
Land pollution isaresultof dumpinggarbage,waste,andothertoxinsmakingthe landcontaminatedorpolluted.The
source of landpollution comesfromthe humanelementsuchaslittering,andwaste thatiswashedashore fromboats,
oil rigs,and sewage outlets.Withouttakingmeasuresnow toreduce pollutionlevels,permanentchangestothe land
can occur. The adverse changestothe environmentdue tolandpollutionare subtle,butthe problemismuchbigger
than itappears.It is a major problemaroundthe worldandis causedby a varietyof factors.
Various Causesof Land Pollution
1. Deforestationand soil erosion
Whenforestsare clearedfordevelopmentandtomeetthe demandforwoodsupply,the soil isloosenedinthe process.
Withoutthe protectionof the trees,the landbecomesbarrenovertime andstartsto erode.
2. Agricultural chemicals
Part of the farmingprocessofteninvolvesthe use of harmful pesticidesandinsecticidestoprotectcrops.However,the
chemicalscancause the landto become barren.The once-fertilesoil isthenmore susceptible toenvironmental
elements,suchasthe wind.
3. Industrialization
The Industrial Revolutionmayhave resultedinsignificantpositive changestothe economyandsociety,butitalsoledto
significantpollutionof the land.Throughunsafe disposal practicesforchemicalsusedinmanufacturing,poorre gulation,
and the overwhelmingnumberof industriesandfactoriesthatare pollutingthe landdaily,industrializationhasbecome
one of the maincontributorstothe pollutionproblem.
4. Mining
The miningprocesscan leadtothe creationof large open spacesbeneaththe surface of the earth.Thiscan resultinthe
landcavingin,whichcompromisesthe integrityof the land.Miningalsoresultsinharmful chemicals,suchasuranium,
beingdisturbedandreleasedintothe environment.
5. Landfills

3. The garbage foundat landfillsisfilledwithtoxinsthateventuallyseepintothe earth.Duringrains,the toxinsare washed
intootherareas andthe pollutionisspread.Asthe populationgrows,the amountof garbage fillinglandfillsalsogrows.
6. Human sewage
Untreatedhumanwaste can produce toxicgasesthat can seepintothe ground.Aswithair pollution,the soil qualityis
negativelyimpacted,andlandnearbycanbe contaminated.Inadditiontothis,the probabilityof humanillnesses
occurringincreases.
7. Industrialization
Due to an increase indemandforfood,shelter,andhouse,more goodsare produced.Thisresultedincreationof more
waste that needstobe disposedof.Tomeetthe demandof the growingpopulation,more industrieswere developed
whichledtodeforestation.Researchanddevelopmentpavedthe wayformodernfertilizersandchemicalsthatwere
highlytoxicandledtosoil contamination.
8. Constructionactivities
Due to urbanization,alarge numberof constructionactivitiesare takingplace whichhasresultedinlarge waste articles
like wood,metal,bricks,plasticthatcan be seenbynakedeyesoutside anybuildingoroffice whichisunder
construction.
9. Nuclearwaste
Nuclearplantscan produce a huge amountof energythroughnuclearfissionandfusion.The leftoverradioactive
material containsharmful andtoxicchemicalsthatcanaffecthumanhealth.Theyare dumpedbeneaththe earthto
avoidanycasualty.
RemediestoLand Pollution
There are several possiblesolutionstolandpollution,including conservation.
Conservationfocusesonpreservingnatural resources,suchas soil and plants. The effortstoconserve resourcescan
start withutilizingsustainable practices.Forinstance, leavingsome of the treesinaforestto naturallydie anddecay.
Thisnot onlyleavesthe coverneededforthe soil andothervegetation,butithelpstoprovide the nutrientsthatthe soil
needstoremainfertile.
As citizensof asocietywe have a responsibilityto manage our waste sustainably.We candothisfollowingthe five R's
of waste management:reduce,reuse,recycle,recoverandresidual management.
Reference:(https://www.learnz.org.nz/redvale181/bg-standard-f/the-5-r%27s-of-waste-management#:)
Reduce
Reducingwaste isthe mostimportantthingwe can do.By reducingwaste,we avoidthe unnecessaryuse of resources
such as materials,energyandwater.Itmeansthere islesswaste tomanage.
How can we reduce waste?
 Buy inbulkto reduce packaging
 Take a reusable shoppingbagwithyousoyou don'thave to use a paperor plasticbag fromthe shop
 Say ‘no’to a plasticshoppingbagwhenyouonlyhave a couple of items
 Choose productsthatuse lesspackaging
 Buy reusable itemsratherthan disposable ones
 Sticka "nojunkmail"signon yourletterbox
 Take your lunchto school ina reusable container.

4. Reuse
The nextmost importantthingwe cando is reuse waste material.Thatwayitdoesn'tgo inthe rubbishandendup in
the landfill.Italsomeansyoudon'thave to buya new product.That savesyou moneyandsavesthe energyand
resourcesthatwouldhave beenusedtomake the new product.
How can we reuse waste?
 Give unwantedtoysandbooksto hospitalsorschools
 Put unwantedclothesinusedclothingbins
 Use plasticcontainersforfreezingorstoringfooditems
 Save wrappingpaperandboxestouse again
 Use oldjars forstorage
 Take old magazinestoyourlocal doctor's or dentist'ssurgery
 Shopat secondhand storesor use online tradingwebsitestobuyitemsthatare unwantedbyothers
 Take householditemstoyourcouncil’sresource recoverycentre
 Make memopadsout of waste paper
 Re-use envelopes - purchase reuse labels.
Recycle
Recyclinginvolvessome formof reprocessingof waste materialstoproduce anotherproduct.Forexample,recycling
plasticbottlestomake buckets.
What can be recycled?
 The main productsthat can be recycledare paper,cardboard,glass,aluminum, tinandplasticcontainers.
 Compostingandwormfarmsare methodsof recyclingorganicwaste.
Buy recycled
 You can buy productsthat are made from recycledmaterials.Thisiscalled‘Closingthe Loop’.
Recyclingin your district

5.  Differentdistrictscollectdifferentrecyclablesatthe kerbside andattheirtransferstations/resource recovery
parks.Contact yourlocal city or districtcouncil tofindout whattheycollect.
Recover
 Thisis the recoveryof waste withoutany pre-processing.Forexample,waste oilsthatcannotbe refinedfor
reuse invehiclescanbe burntfor energyrecovery.Recoveringthe energyfromwaste oil reducesour
dependence oncoal andimportedoil.
Residual Management
Thisis the lastoptionwhenwaste cannotbe usedinany otherway.Usually,thismeanssendingrubbishtoa
landfill. Residual disposal of liquidwaste is normallyintoasewerorseptictank.
It isveryimportantto manage residual solidandliquidwaste properly.Waste notdisposedcorrectlycancause damage
to healthandthe environment.Actnowbefore itislate.
