Namuhla wonke umuntu usebenzisa imikhiqizo yepulasitiki. Nsuku zonke, abantu babhekene nezikhwama, amabhodlela, amaphakheji, iziqukathi nolunye udoti oludala ukulimala okungenakulungiseka emhlabeni wethu. Kunzima ukucabanga, kepha amaphesenti amahlanu kuphela wesisindo esiphelele angaphinde asetshenziswe futhi alungele ukusetshenziswa futhi. Kule minyaka eyishumi edlule, ukwenziwa kwemikhiqizo yepulasitiki kufinyelele kuvuthondaba.
Izinhlobo zokungcola
Abakhiqizi bepulasitiki bakholisa abantu ukuthi basebenzise imikhiqizo yabo kanye, ngemuva kwalokho kufanele ilahlwe. Ngenxa yalokho, inani lezinto zepulasitiki landa ngokwengeziwe nsuku zonke. Ngenxa yalokho, ukungcola kungena emanzini (amachibi, amadamu, imifula, izilwandle), izinhlayiya zenhlabathi kanye nepulasitiki ezisabalele kuyo yonke iplanethi yethu.
Uma ngekhulu leminyaka elidlule iphesenti lepulasitiki lalilingana nelilodwa kusuka kudoti wasekhaya oqinile, khona-ke ngemuva kwamashumi ambalwa eminyaka isibalo sakhuphukela ku-12%. Le nkinga isemhlabeni wonke futhi ayinakushaywa indiva. Ukungabi bikho kwepulasitiki ebolayo kuyenza ibe isici esikhulu sokucekelwa phansi kwemvelo.
Imiphumela eyingozi yokungcola kwepulasitiki
Umthelela wokungcola kwepulasitiki kwenzeka ngezindlela ezintathu. Ithinta umhlaba, amanzi kanye nezilwane zasendle. Uma ususemhlabathini, okokusebenza kukhipha amakhemikhali, nawo, angene emanzini angaphansi komhlaba nakweminye imithombo, ngemuva kwalokho kuba yingozi ukuphuza lolu ketshezi. Ngaphezu kwalokho, ukuba khona kwezindawo zokulahla udoti emadolobheni kusongela ukwakhiwa kwama-microorganism asheshisa ukwanda kwezinto eziphilayo kwepulasitiki. Ukubola kwepulasitiki kukhiqiza i-methane, igesi ebamba ukushisa. Lesi sici sibanga ukusheshisa kokushisa komhlaba.
Uma isemanzini olwandle, ipulasitiki iyabola cishe ngonyaka. Ngenxa yalesi sikhathi, izinto ezinobungozi zikhishelwa emanzini - i-polystyrene ne-bisphenol A. Lokhu kungukungcola okuyinhloko kwamanzi olwandle, okwanda minyaka yonke.
Ukungcoliswa kwepulasitiki nakho kuyonakalisa izilwane. Kujwayelekile ukuthi izilwane zasolwandle zibhajwe emikhiqizweni epulasitiki zife. Amanye ama-invertebrate angagwinya ipulasitiki, nayo ethinta kabi impilo yabo. Izilwane eziningi ezincelisayo zasolwandle zifa ngemikhiqizo yepulasitiki, noma zihlushwa izinyembezi ezinzima nezilonda.
Umthelela esintwini
Abenzi bemikhiqizo yepulasitiki minyaka yonke bathuthukisa imikhiqizo yabo ngokushintsha ukwakheka, okungukuthi: ukufaka amakhemikhali amasha. Ngakolunye uhlangothi, lokhu kuthuthukisa kakhulu ikhwalithi yemikhiqizo, ngakolunye uhlangothi, kunomthelela omubi empilweni yomuntu. Odokotela besikhumba bathole ukuthi ngisho nokuxhumana nezinto ezithile kungadala ukungezwani komzimba kanye nezifo ezahlukahlukene zesikhumba kubantu.
Ngeshwa, abathengi abaningi banaka kuphela ukubukeka kobuhle bepulasitiki, bengazi ukuthi kunomthelela muni omubi emvelweni.
