Ukuzinza kuyikhono lesenzo esikwazi ukuhlangabezana nezidingo zamanje ngaphandle kokuphazamisa ezesikhathi esizayo. Ekubhaleni kwezemfundo ukusimama kwebhizinisi kuvame ukuhlukaniswa ngezinsika ezintathu, ezenhlalo, ezemvelo, kanye nezezimali. Ngokugxila ekuzinzeni, ikhuthaza amabhizinisi ukuthi acabange kakhulu kunonyaka wezimali olandelayo futhi acabangele isikhathi eside sebhizinisi nomthelela elizoba nawo kubantu nasemhlabeni eliwumphumela.
Kungakhathaliseki ukuthi uhlala emadolobheni amakhulu noma emapulazini asemaphandleni, ngokuqinisekile ubona izikhwama zepulasitiki ziphephezela noma nini lapho uphuma endlini. Ezinye zivunguza emigwaqweni njenge-post-apocalyptic tumbleweed, kuyilapho ezinye zibambeka emagatsheni ezihlahla zomgwaqo. Kanti abanye bagcina bentanta emifuleni nasemifuleni yethu baze bathole indlela eya olwandle. Kodwa nakuba lezi zikhwama zepulasitiki zingezinhle neze, empeleni zibangela ukulimala kwangempela, okuphathekayo endaweni enkulu.
Izikhwama zepulasitiki zivame ukuphazamisa imvelo ngendlela engathi sína. Zingena emhlabathini bese zikhipha amakhemikhali anobuthi kancane kancane. Zigcina zibhodloze emhlabathini, okube nomphumela ongemuhle ukuthi izilwane ziyazidla futhi zivame ukuklinywa futhi zife.
Izikhwama zepulasitiki zidala izinhlobo eziningi zokulimala, kodwa izinkinga ezintathu ezikhathaza kakhulu ezivezayo zihlanganisa lezi ezilandelayo:
Ukulimala Kwezilwane Zasendle
Izilwane zilinyazwa yizikhwama zepulasitiki ngezindlela eziningi.
Izilwane eziningi - okuhlanganisa kokubili okusemhlabeni kanye nezinhlobo zasemanzini - zidla izikhwama zepulasitiki, futhi ziba nezinkinga zempilo ezimbi uma seziqedile.
Izinkomo eziningi, ngokwesibonelo, ziyafa unyaka nonyaka ngemva kokudla amasaka epulasitiki agcina esemadlelweni azo. Lokhu kube yinkinga enkulu ikakhulukazi eNdiya, lapho izinkomo ziziningi khona futhi ukuqoqwa kukadoti kwenzeka ngezikhathi ezithile.
Ekuhlolweni kokuhlinzwa, izinkomo eziningi ezilinyazwe yilolu bhubhane lwepulasitiki kutholakala ukuthi zinabo Izikhwama zepulasitiki ezingama-50 noma ngaphezulu emapheshaneni abo okugaya.
Izilwane ezigwinya izikhwama zepulasitiki zivame ukuhlushwa amathumbu, okuholela ekufeni okude, okuhamba kancane nokubuhlungu. Izilwane zingase futhi zifakwe ubuthi ngamakhemikhali asetshenziselwa ukudala izikhwama, noma kumakhemikhali afakwe ipulasitiki ngenkathi idlula endaweni ezungezile.
Futhi ngenxa yokuthi ipulasitiki ayiqhekeki kalula ezingxenyeni zokugaya zezilwane, ngokuvamile igcwalisa izisu zazo. Lokhu kubangela ukuthi izilwane zizwe zisuthi, nakuba ziwohloka kancane, ekugcineni zife ngenxa yokungondleki noma indlala.
Kodwa nakuba imfuyo nezilwane ezifuywayo zisengozini yokuthola izikhwama zepulasitiki, ezinye izilwane zithola ukulimala okukhulu nakakhulu.
Njengoba sezicindezelwe ukucekelwa phansi kwendawo, amashumi eminyaka ezingela kanye nokushintsha kwesimo sezulu, izimfudu zasolwandle zisengozini enkulu yezikhwama zepulasitiki, njengoba zivame benza iphutha nge-jellyfish - ukudla okudumile kwezinhlobo eziningi zofudu lwasolwandle.
Eqinisweni, abacwaningi baseNyuvesi yaseQueensland basanda kunquma ukuthi cishe Amaphesenti angama-52 izimfudu zasolwandle emhlabeni zidle imfucumfucu yepulasitiki - ngokungangabazeki iningi layo lisuka kumasaka epulasitiki.
Amasistimu Endle Avalekile
Ngisho nasezindaweni zasemadolobheni, lapho izilwane zasendle ziyindlala khona, izikhwama zepulasitiki zibangela umonakalo omkhulu endaweni ezungezile. Amanzi agelezayo aqoqa futhi aphathe izikhwama zepulasitiki ezilahliwe futhi ekugcineni aziwashele kuzo amapayipi endle.
Uma sezikulezi zitamkoko, izikhwama zivame ukwakha izigaxana nezinye izinhlobo zemfucumfucu, futhi ekugcineni zivimbe ukugeleza kwamanzi.
Lokhu kuvimbela amanzi agelezayo ukuthi angaphumi kahle, okuvame ukuphazamisa labo abahlala noma abasebenza kuleyo ndawo.
Isibonelo, imigwaqo ivame ukugcwala lapho imisele yendle ivaleka, okuphoqa ukuthi ivalwe kuze kuphele amanzi.
La manzi engeziwe angonakalisa izimoto, izakhiwo kanye nezinye izinto, futhi aqoqa ukungcola futhi akusakaze kude nakude, lapho edala umonakalo owengeziwe.
Indle evalekile yeziphepho ingaphazamisa nokugeleza kwamanzi kuzo zonke izindawo zamanzi zasendaweni. Amapayipi endle avaliwe angalambisa amaxhaphozi endawo, imifudlana nemifudlana yamanzi awadingayo, okungaholela ekufeni okukhulu futhi kwezinye izimo, ukuwa ngokuphelele.
Ukuwohloka kobuhle
Ayikho impikiswano eningi mayelana nomthelela wobuhle izikhwama zepulasitiki ezinawo endaweni.
Iningi labantu lingavuma ukuthi izikhwama zepulasitiki zonakalisa ukubukeka kwayo yonke indawo ongayicabanga, kusukela emahlathini nasemasimini kuya ezingwadule namaxhaphozi.
Kodwa, lokhu konakala kobuhle akuyona into engathi shu; empeleni ingaba nomthelela omkhulu empilweni yomuntu, emasikweni nasemnothweni.
Sekuyisikhathi eside ososayensi bazi ukuthi ukubukwa kwezindawo zemvelo kunikeza izinzuzo eziningi.
Phakathi kwezinye izinto, izindawo zokuhlala zemvelo kanye nezindawo eziluhlaza zisiza nciphisa izikhathi zokuthola kabusha futhi bathuthukise imiphumela yeziguli zasesibhedlela, bayasiza uku thuthukisa ukugxila nokugxila phakathi kwezingane, bayasiza ekunciphiseni ubugebengu futhi bayasiza ukwandisa amanani ezakhiwo.
Kodwa lapho lezi zindawo zokuhlala zigcwele izikhwama zepulasitiki nezinye izinhlobo zemfucumfucu, lezi zinzuzo ziyancipha.
Ngakho-ke, kubalulekile ukwazisa ukubaluleka kobuhle bezindawo zemvelo, ukuthatha izinyathelo zokunciphisa ukungcoliswa kwezikhwama zepulasitiki nokubhekana nalezi zinkinga lapho kuthuthukiswa. inqubomgomo yomphakathi.
Ubukhulu Benkinga
Kunzima ukubamba ububanzi benkinga yezikhwama zepulasitiki, naphezu kokutholakala kwezikhwama zepulasitiki endaweni.
Akekho owazi kahle ukuthi zingaki izikhwama ezilahla udoti emhlabeni, kodwa abacwaningi balinganisela lokho 500 billion esetshenziswa emhlabeni wonke unyaka nonyaka.
Iphesenti elincane lalokhu ligcina seligaywe kabusha, futhi abanye abantu bazama ukuphinda basebenzise izikhwama zepulasitiki ezindala ngezinye izinjongo, kodwa iningi lezikhwama zepulasitiki zisetshenziswa kanyekanye. Eziningi zilahlwa kudoti, kodwa amaphesenti amaningi agcina engcolisa izindawo zemvelo.
Ingxenye yesizathu esenza ukuthi izikhwama zepulasitiki zibe nenkinga zihlobene nempilo yazo ende.
Nakuba ithawula lephepha liphuka enyangeni, futhi ucezu lweplywood lungathatha unyaka ukwehlisa izinga, izikhwama zepulasitiki ziphikelela isikhathi eside - ngokuvamile amashumi eminyaka, futhi kwezinye izimo amakhulu eminyaka.
Eqinisweni, izikhwama zepulasitiki ezingena emifuleni, emachibini noma olwandle neze biodegrade ngokuphelele. Kunalokho, zihlukana zibe izingcezu ezincane nezincane, ekugcineni iba "i-microplastics," ezingaphansi kwamamilimitha amahlanu ubude.
Kodwa nakuba lezi ama-microplastics awaphazamisi ngokubonakalayo njengezikhwama zepulasitiki, zisabangela izinkinga eziningi ezilwaneni zasendle kanye ne-ecosystem yonkana.
Isifinyezo
Njengoba ubona, izikhwama zepulasitiki ziyinkinga enkulu yemvelo.
Njengohlobo lwezilwane, kuzodingeka sihlole ngokucophelela izinselele ezizethulayo futhi sisebenzise amasu okungenzeka anciphise inani lomonakalo wemvelo eziwudalayo.
Singathanda ukuzwa imicabango yakho ngalolu daba.
Yiziphi izinhlobo zezinyathelo ongancoma ukuthi sizithathe ukuze sinciphise umonakalo odalwe izikhwama zepulasitiki?
