Kuyacaca ukuthi abantu balahla amathani namathani epulasitiki olwandle ngendlela engalawulwa phakathi namashumi eminyaka adlule. Le plastiki yakha inqwaba yonyawo olwandle. Futhi ukuthi amapulasitiki into esasiyisebenzisa sasinayo nsuku zonke usuku nosuku nokuthi sigcina singasetshenziswanga ngisho nokusebenzisa kabusha ukukalwa ngendlela efanele. Ukugwema lesi simo nokuhlanza ulwandle ngepulasitiki, iphrojekthi yazalwa Ukuhlanzwa Kwe-Ocean. Kungumsebenzi ozama ukuhlanza izilwandle ze-placid esisusa abantu.
Kule ndatshana sizokutshela ukuthi iphrojekthi ye-Ocean Cleanup iqukethe ini nokuthi ineziphi izici.
Ukungcola kwezilwandle ngamapulasitiki
Ipulasitiki yinto esiyisebenzisa nsuku zonke ngobuningi futhi engatholakala ezindaweni ezinjengemifula yamanzi nasolwandle ngokukhipha izindawo ezisemadolobheni. Nakanjani lo mkhiqizo ungcolisa kangangokuba uphelela olwandle nasezilwandle futhi ubeke impilo yezilwane zasolwandle kanye neyethu engcupheni. Sithi kubeka impilo yethu engcupheni kusukela singafaka amapulasitiki amancane ngochungechunge lokudla. Lo plastiki uphuzwa yizilwane njengoba zitholakala zintanta olwandle nasolwandle emhlabeni jikelele.
Njengamanje kunezinhloso ezithile ezenziwayo ukunciphisa imfucuza esemanzini. Le phrojekthi yaziwa nge-The Ocean Cleanup. Kule phrojekthi kukhona ubuchwepheshe obulungiselelwe ukukwazi ukukhipha imfucuza epulasitiki nokuyivimbela ukuthi ingaphinde ingcoliswe.
Emhlabeni jikelele, kukhiqizwa inani elikhulu lepulasitiki eligcina olwandle nasezilwandle zomhlaba wonke. Singabona cishe noma kuphi inqwaba yotshani, iziqukathi, amanetha anoma yiluphi uhlobo, amabhodlela, izikhwama, njll. Zonke lezi zinsalela zakha inqwaba yeziqhingi zikadoti maphakathi nolwandle. Sekuvele iziqhingi ezi-5 zepulasitiki olwandle. Okukhulu kunakho konke lokhu kuphakathi kweHawaii neCalifornia futhi kuye kwabizwa ngokuthi isiqephu esikhulu sikadoti sePacific. Lezi ziqhingi zepulasitiki zakhiwa yimisinga yolwandle egcina ekugcineni konke lokhu kudoti endaweni eyodwa ngqo.
Mangisho nje ukuthi lokhu kungcola kubangela ukwehla kwekhwalithi yamanzi futhi kubeka engcupheni impilo yezilwane zasemanzini. Lezi zilwane zivame ukudla imfucuza, zikuthatha njengokudla okuvamile. Ngaphezu kwalokho, abanye abaningi baphambanisa la mapulasitiki futhi babanjwa kuwo. Izimfudu zasolwandle yizilwane ezenza iphutha kakhulu ezikhwameni zepulasitiki ze-jellyfish futhi lapho zifakwa zidala izinkinga ezinkulu zempilo ngisho nokufa. Ezinye izilwane zibanjwa yimfucuza yepulasitiki bese zilimala kabi. Lezi zilonda zibavimbela ekunyakazeni, ukondla noma ukwenza noma yimuphi umsebenzi onjengokuzingela.
Imiphumela yokungcola kolwandle
Njengoba kulindelwe, le nkinga ayithinti nje kuphela izilwane zasolwandle, kepha nabantu. Lokhu kungenxa yokuthi sidla izinhlanzi eziningi zasolwandle. Ukungcola esiye sazibangela kona kungashintsha ukulingana kwemvelo futhi kugcine emzimbeni wethu ngochungechunge lokudla.
Ukunciphisa izinkinga zokungcola kwepulasitiki, kwazalwa iphrojekthi ye-Ocean Cleanup. Inhloso yalo enkulu ukusiza ukuhlanza imvelo yasolwandle, yize lezi zinyathelo zingasheshi ngokwanele ukuthi zikwazi ukumisa ukungcoliswa kahle. Kudingeka amaphrojekthi amakhulu angahlanganisa ukuhlanzwa kwalokho osekuqoqiwe olwandle nokuvimbela ukwethulwa kukadoti omusha. Kusetshenziswa izindlela ezijwayelekile ezifana nezikebhe kuzobabiza izigidigidi zamaRandi nezinkulungwane zeminyaka ukuzisebenzisa. Isixazululo yi-The Ocean Cleanup.
I-Ocean Cleanup
Le phrojekthi yazalwa ngesandla somfundi waseDashi uBoyan Slat owaphakamisa uhlelo olusebenzayo lokuhlanza amapulasitiki olwandle. Lolu hlelo lusesekuqaleni futhi kufanele luguqulwe futhi lwenziwe ngcono ngokuhamba kwesikhathi. Ukusebenza kwale phrojekthi kuphezulu impela. Ukuhlanzwa Kwe-Ocean ihlose ukukhipha imfucuza olwandle nasolwandle ngokusebenzisa indlela yokwenziwa. Le ndlela isho ukuthi umuntu akudingeki angenelele ukuze ayisebenzise, kepha usebenzisa ngokunenzuzo imvelo nemimoya yolwandle yokuhlungwa nokuqoqwa kwepulasitiki.
Ngale ndlela, le projekthi ngokuyinhloko isuselwa ekufakweni kwezinhlelo zokuvimba ezintantayo ezisendaweni ekahle eNyakatho yePacific Ocean ekwazi ukuqoqa udoti odonswa yimisinga yolwandle nomoya. Lesi sithiyo esintantayo sinokuningi noma okuncane ubude obungamamitha ayi-600 ubude futhi buzoba nezingalo ezimbili ezixhunywe kwizithiyo ezicwiliswe ekujuleni okungaba ngamamitha amathathu. Lokhu kuvimbela ukungcola kungaphunyuki ngaphansi. Izingalo ezintantayo zibekwa ngo-V ukuze zikwazi ukugxilisa yonke imfucuza engxenyeni emaphakathi yesithiyo.
Kufakwe ipulatifomu eyi-cylindrical esebenza njengesiqukathi ukugcina imfucuza. Ngosizo lwezinye izikebhe Imfucuza izosuswa cishe zonke izinsuku ezingama-45 bese ibuyiselwa ezweni. Uma sesiphinde sabuyiselwa empucukweni, singaphinde sisetshenziswe kabusha noma sithengiswe ukuze sisetshenziswe futhi, kuqinisekiswe ukuthi ukuzihlanza kolwandle nolwandle kuyasimama.
Isebenza Kanjani Ukuhlanzwa Kwe-Ocean
Njengoba kukhona ama-5 futhi kunodoti omningi osatshalaliswa olwandle emhlabeni jikelele, kuhloswe ukufaka izithiyo eziqhingini ezinhlanu. Kulezi zindawo, imisinga yasolwandle iyimbangela yokugcina udoti kulezi zindawo. Futhi kunokuthi kunemisinga yolwandle eyisiyingi ku- Enyakatho naseningizimu yePacific Ocean, oLwandlekazi lwaseNdiya kanye naseNyakatho naseningizimu ye-Atlantic Ocean. Kulezi zindawo iphrojekthi izokwazi ukusiza ukubamba amapulasitiki okwehlukahluka okukhulu kosayizi. Ukusuka kulokhu lezo zingcezu ezincane ezino-mm kuphela ngosayizi kudoti omkhulu njengamanethi amakhulu okudoba.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngephrojekthi ye-The Ocean Cleanup.
