I-BMW, iVolvo, i-Google kanye ne-Samsung SDI izinkampani zokuqala ukusayina umyalelo wokumisa we-World Wildlife Fund (WWF) wokumba izimayini ezijuleni kolwandle.
Ngokwale nhlangano engekho ngaphansi kukahulumeni (NGO), lezi zinkampani ziyazibophezela ukuthi ngeke zithole izimbiwa phansi ngaphansi kolwandle, ukuze zingawafaki amaminerali anjalo ohlelweni lwazo lokuhlinzekwa kwempahla futhi zinganikezi ngezimali noma yiziphi izimayini ezijulile olwandle.
Khumbula ukuthi kunendawo kuLwandlekazi i-Pacific, ekujuleni phakathi kwamakhilomitha angu-4 no-6 - endaweni enkulu enwebeka amakhilomitha amaningi phakathi kweHawaii neMexico - lapho kutholakala khona ukugxila okukhulu kwamaqhuqhuva e-polymetallic.
Ama-nodule e-polymetallic, ayini?
Lawa maqhuqhuva (abukeka njengamatshe amancane…), ubukhulu bawo buhluka phakathi kuka-1 cm no-10 cm, amadiphozithi nje e-ferromanganese oxides nezinye izinsimbi, njengalezo ezidingekayo ukuze kukhiqizwe amabhethri.
Akhona kuzo zonke izilwandle ngisho nakwamanye amachibi, agqama ngokuba phezu kolwandle, ngakho-ke awadingi noma yiluphi uhlobo lokumba.
Lesi isihloko esike sakhuluma ngaso ngaphambili, lapho i-DeepGreen Metals, inkampani yaseCanada yezimayini ezijulile zolwandle, iphakamisa ukumba izimayini zasolwandle njengenye indlela kunezimayini zasogwini.
Uma kucatshangelwa ukushoda kwezinto zokusetshenziswa ukwenza wonke amabhethri adingekayo ukuze aphendule ekucindezelweni okwandayo kokufaka izimoto zikagesi emakethe, ukumba la maqhuqhuva e-polymetallic kusuka phansi olwandle kugqama njengesixazululo.
Yini embi?
Kodwa-ke, akukuningi okwaziwayo mayelana ne-ecosystem kanye nezinhlobonhlobo zezinhlobo zezilwane ezihlala endaweni eqoqweniselwa phansi olwandle, ngakho-ke umthelela wangempela walo mkhuba kuleyo nqubo yemvelo awaziwa. Futhi lesi yisizathu esiyinhloko esisekela ukumiswa manje “okuphakanyiswe” yi-WWF.
"Njengoba iningi lendawo ehlala ekujuleni kolwandle okusamele ihlolwe futhi iqondwe, umsebenzi onjalo ubungeke ube nombono omfishane ngobudlabha," kusho i-NGO, ecashunwe yi-Automotive News.
Ngalo mqondo, ukumiswa kubiza ukuthi kuvalwe imisebenzi yezimayini ekujuleni kolwandle kuze kube yilapho izingozi seziqondwa ngokugcwele futhi zonke ezinye izindlela seziphelile.
I-BMW, i-Volvo, i-Google ne-Samsung SDI ngokubambisana
Ngokusho kwe-Automotive News, i-BMW isivele yakwenza kwaziwa ukuthi izinto ezingavuthiwe ezivela ezimayini zasogwini “aziyona inketho” okwamanje ngoba azikho izinto ezitholwe ngokwesayensi ezanele zokuhlola ubungozi bemvelo.
AbakwaSamsung SDI baphinde bathi bekungumenzi wamabhethri wokuqala ukubamba iqhaza ohlelweni lwe-WWF. Ngokulandelayo, iVolvo ne-Google abakakaphawuli kulokhu “kuma”.
Kodwa naphezu kwalesi sicelo sokumiswa esisayiniwe manje, izinkampani zezimayini ze-subsea fund ziyaqhubeka nomsebenzi wokulungiselela futhi zizama ukuthola amalayisensi ale misebenzi.
Kuze kube manje, phakathi kwezinkampani ezinamalayisense okuhlola izindawo ezijulile zolwandle kukhona i-DeepGreen - esishiwo ngenhla -, i-GSR kanye ne-UK Seabed Resources.
I-DeepGreen ingomunye wabasekeli abakhulu balesi sixazululo, ethi sisimama kakhulu kunezimayini zasogwini, njengoba idala imfucuza encane futhi ngenxa yokuthi amaqhuqhuva anensimbi ephakeme kakhulu kunalawo atholakala kumadiphozithi asogwini.
I-GSR, ngomlomo womqondisi wayo ophethe, u-Kris van Nijen, isikwazisile kakade ukuthi “izofaka isicelo senkontileka yezimayini kuphela uma isayensi ikhombisa ukuthi, ngokombono wemvelo nenhlalo, amaminerali asuka olwandle anenzuzo ngaphezu kwalokho. - okuwukuthembela kuphela emabhomuni agqitshwayo amasha nakhona."
INorway ifuna ukuba iphayona
INorway, okwathi ngo-2020 yaba yizwe lokuqala emhlabeni lapho izimoto zikagesi zimelela ngaphezu kuka-50% wezimoto ezintsha ezithengisiwe, ifuna ukuba yiphayona ezimayini zasolwandle futhi ingakhipha amalayisense ekuqaleni kuka-2023.
Ekhuluma ne-Automotive News, uTony Christian Tiller, unobhala wezwe ophikweni lukawoyela namandla eNorway, wenqabile ukuphawula ngalokhu kumiswa, kodwa ukuqinisekisile ukuthi uhulumeni walelo zwe elisenyakatho ye-Europe “useluqalile kakade uhlelo lokuvulela ulwandle olunezimayini oluphezulu, lapho izimo zemvelo ziyingxenye ebalulekile ekuhlolweni komthelela”.
