Ukufunyanwa kwe-tellurium kubangela ingxaki: kwelinye icala, kuyimfuneko ukudala inani elikhulu lemithombo yamandla aluhlaza, kodwa ngakolunye uhlangothi, izibonelelo zemigodi zingenza umonakalo omkhulu kwindalo.
Yintoni urhwebo phakathi kokudalwa kwamandla aluhlaza kunye nokutshatyalaliswa kwemigodi
Ngokutsho kwengxelo kwiMIT Technology Review, abaphandi bafumene phantsi kolwandle isinyithi esinqabileyo, kodwa ubukhulu becala bazisa ukufumanisa ingxaki ecinezelayo: kwinkqubo yokusetyenziswa kwemithombo yendalo, apho kufuneka sidwebe umgca.
Ngokutsho kwe-BBC, izazinzulu zichonge isityebi esinqabileyo kakhulu se-metal metal tellurium kwiintaba zolwandle iikhilomitha ezingama-300 ukusuka kunxweme lweziqithi ze-canary. Malunga ne-1, 000 yeemitha ngaphantsi komphezulu wolwandle, ilitye elinee-intshi ezimbini ezingqingqwa kwiintaba eziphantsi kolwandle liqulethe i-tellurium yentsimbi enqabileyo ngaphezu kwama-50, 000 amaxesha asemhlabeni.
I-Tellurium ingasetyenziswa kwezinye zeeseli zelanga ezisebenza kakuhle emhlabeni, kodwa ikwanazo iingxaki ekunzima ukuzisebenzisa, njengeentsimbi ezininzi ezinqabileyo zomhlaba. Intaba inokuvelisa iitoni ze-2,670 ze-tellurium, ezilingana nekota yesibonelelo sehlabathi, ngokutsho kweprojekthi ekhokelwa nguBram Murton.
Esi ayisosihlandlo sokuqala ukuba ukumbiwa kweentsimbi ezinqabileyo kuqatshelwe. Zonke iintsimbi ziyaziwa ukuba zikhona kumatye asezantsi olwandle, kwaye eminye imibutho ibonise umdla wokuzemba. Inkampani yaseCanada iNautilus Minerals, ekuqaleni ibijongene nokuchaswa ngurhulumente, kodwa ngoku isebenzela ukukhupha ubhedu negolide kunxweme lwasePapua ngo-2019. ukuqala ngokusemthethweni. Ubuncwane bolwandle bunomtsalane, kwaye uphando lwethu lwangoku kwiimoto zombane kunye namandla acocekileyo kwandisa imfuno yesinyithi esinqabileyo kunye neentsimbi ezixabisekileyo. Ubutyebi bomhlaba ngoku kubiza ukuxhaphazwa, kodwa ukufikelela kobu butyebi ukusuka emazantsi olwandle kubonakala ngathi kuya kuhlangabezana nemfuno ekhulayo yamandla acocekileyo kwixesha elizayo. Kwaye kucacile ukuba abaphuhlisi banokwenza inzuzo enkulu.
Kodwa umnqa kukuba ngoku kukho abaphengululi abaninzi abaxhalabileyo ngokonakala kwendalo kwezi nkqubo. Ekuqaleni kwalo nyaka, umzekelo, uhlalutyo lovavanyo lwemigodi enzulu elwandle lubonise ukuba nolingo oluncinane lunokutshabalalisa i-ecosystem yaseLwandle. Uloyiko kukuba isenzo esikhulu siya kukhokelela kwintshabalalo enkulu. Kwaye akucaci ukuba i-ecosystem iphazamisekile, iya kubangela njani iziphumo ezibi, nokuba inokuphazamisana neepateni zemozulu zolwandle okanye ukwahlulwa kwekhabhoni.
Ukufunyanwa kwe-Tellurium kuphakamisa ingxaki ephazamisayo: kwelinye icala, kuyimfuneko ukudala inani elikhulu lemithombo yamandla aluhlaza, kodwa ngakolunye uhlangothi, ezi zixhobo zemigodi zingabangela ingozi enkulu kwindalo. Oku kuphakamisa umbuzo wokuba izibonelelo zangaphambili zigqithise imiphumo enokubakho yeyokugqibela. Ukuphendula lo mbuzo akukho lula, kodwa ukucinga ngawo kusinika ukuqonda ngakumbi ukuba sikulungele na ukuphonononga ixabiso labo elipheleleyo.
