Umlando wezikhwama zepulasitiki kusukela ekuzalweni kuya ekuvinjweni
Ngawo-1970, izikhwama zokuthenga zepulasitiki zaziseyinto entsha engavamile, futhi manje seziwumkhiqizo otholakala yonke indawo emhlabeni wonke onomkhiqizo wonyaka wethriliyoni eyodwa.Izinyathelo zabo zisemhlabeni wonke, kuhlanganise nengxenye ejulile ekujuleni kolwandle, isiqongo esiphakeme kunazo zonke se-Mount Everest kanye nezinguzunga zeqhwa ezishisayo.Ipulasitiki idinga amakhulu eminyaka ukuze yehlise izinga.Ziqukethe izithasiselo ezingakhanga izinsimbi ezisindayo, ama-antibiotics, izibulala-zinambuzane nezinye izinto ezinobuthi.Izikhwama zepulasitiki zibeka izinselele ezinzima emvelweni.
Zenziwa kanjani izikhwama zepulasitiki ezilahlwayo?Ivinjelwa kanjani?Kwenzeka kanjani lokhu?
Ngo-1933, imboni yamakhemikhali eNorthwich, eNgilandi, ngokungaqondile yakha ipulasitiki-polyethylene esetshenziswa kakhulu.Nakuba i-polyethylene yakhiqizwa ngezinga elincane ngaphambili, lesi bekungokokuqala ngqa ukuthi kuhlanganiswe izinto ezisebenza ezimbonini, futhi yasetshenziswa ngasese amasosha aseBrithani phakathi neMpi Yezwe II.
1965-Isikhwama sokuthenga esihlanganisiwe se-polyethylene sagunyazwa yinkampani yaseSweden iCelloplast.Lesi sikhwama sepulasitiki esaklanywa unjiniyela uSten Gustaf Thulin ngokushesha sashintsha izikhwama zendwangu nephepha eYurophu.
1979-Sezivele zilawula ama-80% emakethe yezikhwama eYurophu, izikhwama zepulasitiki ziya phesheya futhi zethulwa kabanzi e-United States.Izinkampani zepulasitiki ziqala ukumaketha ngobudlova umkhiqizo wazo njengongcono kunezikhwama zephepha nezisebenziseka kabusha.
1982-I-Safeway ne-Kroger, amaketanga amabili esuphamakethe amakhulu e-United States, ashintshela ezikhwameni zepulasitiki.Izitolo eziningi zilandela okufanayo futhi ekupheleni kweshumi leminyaka izikhwama zepulasitiki zizobe sezithathe indawo yephepha emhlabeni jikelele.
Ngo-1997-Itilosi kanye nomcwaningi uCharles Moore uthola iGreat Pacific Garbage Patch, enkulu kunazo zonke ezindaweni eziningana olwandle olwandle lapho kuye kwanqwabelana khona imfucumfucu yepulasitiki, esongela ukuphila kwasolwandle.Izikhwama zepulasitiki zidume ngokubulala izimfudu zasolwandle, ezicabanga ngephutha ukuthi ziyi-jellyfish futhi ziyawadla.
2002-I-Bangladesh iyizwe lokuqala emhlabeni ukusebenzisa ukuvinjelwa kwezikhwama zepulasitiki ezizacile, ngemuva kokuthi kutholakale ukuthi zibambe iqhaza elikhulu ekuvimbeleni amasistimu wokudonsa amanzi ngesikhathi sezikhukhula.Amanye amazwe aqala ukulandela okufanayo.2011-Umhlaba udla izikhwama zepulasitiki eziyisigidi njalo ngomzuzu.
2017-Kenya isebenzise "ukuvinjelwa kwepulasitiki" okuqinile kakhulu.Ngenxa yalokho, amazwe angaphezu kuka-20 emhlabeni wonke asebenzise "ama-plastic restriction orders" noma "ama-plastic ban orders" ukuze alawule ukusetshenziswa kwezikhwama zepulasitiki.
2018 - "Isinqumo Esisheshayo Sempi Yepulasitiki" sikhethwe njengendikimba yoSuku Lwezemvelo Lomhlaba, kulo nyaka isingathwe yi-India.Izinkampani kanye nohulumeni emhlabeni jikelele baye bazwakalisa ukweseka kwabo, futhi baye baveza ngokulandelana ukuzimisela nokuzibophezela kwabo ekuxazululeni inkinga yokungcoliswa kwepulasitiki okusetshenziselwa ukusetshenziswa kanye.
2020- "Ukuvinjelwa kwamapulasitiki" emhlabeni wonke ku-ajenda.
Thanda impilo futhi uvikele imvelo.Ukuvikelwa kwemvelo kuhlobene eduze nempilo yethu futhi kusenza sibe isisekelo sezinye izinto.Kufanele siqale ngezinto ezincane futhi siqale ohlangothini, futhi sifinyelele umkhuba omuhle wokusebenzisa kancane ngangokunokwenzeka noma singalahli izikhwama zepulasitiki ngemva kokusetshenziswa ukuvikela amakhaya ethu!
