Los iihambo ezikumgangatho ophezulu zizixeko eziyinyaniso ezidadayo ezinamawaka abakhweli ezithi zenze ungcoliseko olubonakalayo kwaye inkcitho yamandla.
Umbutho okhuselayo obizwa ngokuba yi-Oceana wenze uphando oluchaza iziphumo zokungqonge iinqanawa zokuhamba ngenqanawa.
Babala ukuba inqanawa enabakhenkethi abangama-3000 inokuvelisa umkhweli ngamnye yonke imihla: iilitha ezingama-300 zamanzi amdaka angwevu kunye neelitha ezingama-40 zenkunkuma yelindle, iilitha ezili-10 zebhili okanye ulwelo olusuka enqanaweni, i-3,5 kg yenkunkuma kunye neegram ezingama-30 inkunkuma enetyhefu.
Ukuqukumbela, kuya kufuneka ukuba inqanawa nganye ivelise isixa esikhulu senkunkuma kunye nongcoliseko.
Kodwa eyona nto ixhalabisayo kukuba umthetho wangoku wamazwe onke mdala kwaye awuhambelani nenyani yangoku, kuba umzekelo ugunyazisa iinqanawa ukuba zilahle inkunkuma yendalo elwandle ukuba nje ziimayile ezi-4 ukusuka elunxwemeni xa bafumana uhlobo lonyango kwaye ukuba ayingawo amanzi amdaka ngeekhilomitha ezili-12 ukusuka elunxwemeni.
Enye into echazwa ngu-Oceana kukuba iinqanawa zokuhamba ngenqanawa zisebenzisa isixa esikhulu samafutha. Inqanawa nganye inokuyisebenzisa fuel ngaphezu kwe-12.000 iimoto kodwa nomgangatho wamafutha asetyenzisiweyo uvelisa isixa esikhulu izinto ezikhutshwayo ze CO2 nesalfure phakathi kwezinye iigesi ezingcolisayo.
Impembelelo kwindalo yalo msebenzi wabakhenkethi ibaluleke kakhulu, iinkampani ezenza lo msebenzi ziqala ukwenza amanyathelo athile okunciphisa iziphumo zayo zokusingqongileyo, kodwa zisencinci.
Abasemagunyeni bamanye amazwe kufuneka baphucule kwaye bahlaziye umthetho malunga nokuhamba ngenqanawa, ukumisela nokuseka uxanduva lokusingqongileyo kunye nemigangatho yokhathalelo lwendalo kunye nokuziphatha kulwandle oluphezulu.
Umsebenzi wezoKhenketho unokuzinza kodwa kuyafuneka ukubandakanya itekhnoloji kunye neenkqubo ezintsha ukunciphisa amanqanaba ongcoliseko.
Ulwandle neelwandle zezinto zonke, kodwa hayi kodwa azinakusetyenziswa njengendawo yokulahla inkunkuma enkulu engalawulekiyo.
