Namuhla izikhwama zepulasitiki zikhona yonke indawo. Iningi lemikhiqizo ezitolo nasezitolo ezinkulu ligcwele kuyo, futhi nabantu bayayisebenzisa empilweni yansuku zonke. Izintaba zemfucumfucu ezivela ezikhwameni zepulasitiki zigcwalise amadolobha: zinamathela emigqonyeni kadoti bese zigingqika emigwaqweni, zibhukuda emizimbeni yamanzi futhi zibambe ngisho nasezihlahleni. Umhlaba wonke uminza kule mikhiqizo ye-polyethylene. Kungaba lula ukuthi abantu basebenzise izikhwama zepulasitiki, kepha bambalwa abantu abacabanga ukuthi ukusebenzisa le mikhiqizo kusho ukonakalisa imvelo yethu.
Amaqiniso esikhwama seplastiki
Cabanga nje, isabelo sezikhwama kuyo yonke imfucuza yasekhaya cishe singama-9%! Le mikhiqizo ebonakala ingenangozi futhi elula kangako ayilona ize engozini. Iqiniso ngukuthi zenziwe ngama-polymers angaboli endaweni yemvelo, futhi lapho zishiswa emoyeni, zikhipha izinto ezinobuthi. Kuzothatha okungenani iminyaka engama-400 ukuthi isikhwama sepulasitiki sibole!
Ngaphezu kwalokho, maqondana nokungcola kwamanzi, ochwepheshe bathi cishe ingxenye yesine yamanzi ihlanganiswa nezikhwama zepulasitiki. Lokhu kuholela eqinisweni lokuthi izinhlobo ezahlukahlukene zezinhlanzi namahlengethwa, izimvu zamanzi nemikhomo, izimfudu nezinyoni zasolwandle, zithatha ipulasitiki ziyidle, ziyigwinye, zibhajwe ezikhwameni, ngakho-ke zifa kabuhlungu. Yebo, konke lokhu kwenzeka kakhulu ngaphansi kwamanzi, futhi abantu abakuboni. Kodwa-ke, lokhu akusho ukuthi ayikho inkinga, ngakho-ke awukwazi ukuyishalazela.
Ngaphezulu konyaka, okungenani amaphakethe ama-4 trillion anqwabelana emhlabeni, futhi ngenxa yalokhu, inani elilandelayo lezidalwa ziyafa minyaka yonke:
- Izinyoni eziyi-1;
- Izilwane zasolwandle eziyizinkulungwane eziyikhulu;
- inhlanzi - ngamanani angenakubalwa.
Ukuxazulula inkinga "yomhlaba wepulasitiki"
Izazi zemvelo ziphikisana ngokuqinile nokusetshenziswa kwezikhwama zepulasitiki. Namuhla, emazweni amaningi, ukusetshenziswa kwemikhiqizo ye-polyethylene kunqunyelwe, futhi kwamanye kuvunyelwe. IDenmark, i-Germany, i-Ireland, i-USA, iTanzania, i-Australia, iNgilandi, iLatvia, iFinland, iChina, i-Italy, i-India aphakathi kwamazwe alwa namaphakethe.
Ngaso sonke isikhathi, ukuthenga isikhwama sepulasitiki, umuntu ngamunye ulimaza imvelo ngamabomu, futhi lokhu kungagwemeka. Isikhathi eside, le mikhiqizo elandelayo isetshenzisiwe:
- izikhwama zamaphepha zanoma yisiphi isayizi;
- izikhwama ze-eco;
- izikhwama zezintambo ezilukiwe;
- kraft iphepha izikhwama;
- izikhwama zendwangu.
Izikhwama zepulasitiki zifunwa kakhulu, njengoba zilungele ukusetshenziselwa ukugcina noma yimuphi umkhiqizo. Futhi, zishibhile. Kodwa-ke, zilimaza kakhulu imvelo. Isikhathi sokuzishiya, ngoba kunezindlela eziningi eziwusizo nezisebenzayo emhlabeni. Woza esitolo uzothenga ngesikhwama noma i-eco-bag esetshenzisiwe, njengoba kujwayelekile emazweni amaningi emhlabeni jikelele, futhi ungasiza iplanethi yethu ihlanzeke.
