Sekuyisikhathi eside abezemvelo bexwayisa ngemiphumela yezimboni ezihamba ngezikebhe ezindaweni zasolwandle. Izinkampani eziningi zokuhamba ngezikebhe sezivele zidambisa lesi simo ngokufaka izindlela ezisebenza kangcono zokubhekana nodoti, amanzi ampunga namnyama, nokusebenzisa izibaseli ezintsha.
Kodwa-ke, kusenodaba okusamele luxazululwe, futhi lokho ngukuthi i-Union for the Conservation of Nature of Germany ixwayise ngokuthi inani lokudla izivakashi ezikudlayo likhiqiza ukwedlula umanyolo olwandle eCanary Islands.
Kusobala kanjani izinkampani zemikhumbi zikholelwa ukuthi lokhu kuhlaziywa kunama-nuances athile, kodwa I-Union for the Conservation of Nature eJalimane iphethe ukuchitheka kokudla okunomthwalo ngqo okuphonswa ezikebheni ngokubonakala kwe-microalgae emabhishi eCanary Islands. Okhiqizwayo ukukhulisa kakhulu imvelo yasolwandle.
Isixazululo sokunciphisa lokhu asibonakali silula, ngoba ngokungafani nokwenzeka ngepulasitiki, iphepha, ingilazi noma insimbi, Imikhumbi ingalahla ngokusemthethweni imfucuza yokudla olwandle ngaphansi kwemithetho ye-International Maritime Organisation (IMO) elawula leyo doti ecekiwe olwandle oluningi evulekile ingakhishelwa ngaphakathi kwamakhilomitha amathathu olwandle.
Le nhlangano yezemvelo yaseJalimane ikholelwa ukuthi kulo nyaka, i-2018, iCosta Cruises, iMSC neRoyal Caribbean inganikela ngemininingwane emisha emisebenzini yabo yokuvikela imvelo nempilo. Ngokusho kwalaba basosayensi bezemvelo baseJalimane, izinkampani zemikhumbi ezingcolisa kakhulu yi-Aida Cruises neTUI Cruises. Intuthuko enkulu embonini kube ukusetshenziswa kwe-nitric oxide catalyst yokuhambisa, ngaphandle kokwehliswa kusukela ngo-2015, komkhawulo wesibabule wamaphesenti ayi-0,1.
Vele, i-CLIA ayisho lutho ngalolu daba lwe-microalgae.
