Umsi uveliswa xa into isitsha. Umsi uquka iigesi kunye namasuntswana aqinileyo axhonywe kuwo. Ngoko ke umsi yi-aerosol. Kuba umsi ushushu kunomoya oyingqongileyo, umsi uyanyuka xa kungekho moya uwutyhalela phantsi.
Umsi uyingozi kwizilwanyana nakubantu. Iyonakalisa imiphunga. Kuxhomekeka ekubeni umsi uvela kweliphi na amafutha. Umsi ophuma kumlilo weenkuni awunabungozi kangako xa utshisa iplastiki. Kwakhona kuxhomekeke ekubeni umsi ugxininise kakhulu okanye ukuba umoya sele uhlambulule kakhulu.
Umsi ushiya umaleko omnyama kwiindonga zangaphakathi zetshimini, i-soot. Kufuneka uyisuse ngamaxesha athile ukuze umsi ubaleke kakuhle. Ngaphambili, umsizi wawukwasetyenziselwa ukwenza i-inki.
Zeziphi iintlobo zomsi ezikhoyo?
Kuxhomekeke kwizinto ezitshisiweyo. Indima ebalulekileyo nayo idlalwe kukuba kukho ioksijini eninzi ekufutshane xa itshiswa. Ngokomzekelo, ukuba kukho ioksijini eyaneleyo, kunokwenzeka ukuba kuveliswe ikharbon diokside kunekharbon monokside. Ikharbhon diokside ayinayo ityhefu kuba sikwayiphefumlela ngaphandle. Kwelinye icala, ikharbon monoxide yigesi eyityhefu yokwenene.
Ipetroli engafanelekanga, umzekelo, ziinkuni ezimanzi, ioli endala, okanye amafutha. Uthuthu olungakumbi kunye nothuthu lwempukane nalo lungena emoyeni. Oku kwenza umsi ube ngwevu okanye ube mnyama. Iinjini zeenqanawa, umzekelo, zihlala zisebenza kwi-petroleum engakhange icocwe. Ibiza kancinci kodwa iza nomsi omninzi.
Yintoni ekhutshwa yimoto ibizwa ngokuba yi "exhaust gas". Uyalidinga eli gama kuba akukho phantse amacandelo angatshintshiyo kulo. Ukongeza kwiigesi ezahlukahlukeneyo, amathontsi amancinane amanzi aveliswa ngexesha lokutsha. Bafaka umbala omhlophe kumsi womsi. Oku kuphawuleka ngakumbi xa injini isabanda.
Imizi-mveliso inezihluzi ezinokuthi zisetyenziswe ukucoca umsi. Unokufumana impumelelo enkulu ngale nto namhlanje. Iifilitha zokukhupha amanzi nazo zifakwe kwiimoto zedizili. Iziguquli zeCatalytic zisetyenziswa kwiinjini zepetroli. Ezi "post-combustors" ziqinisekisa ukuba ziveliswa iigesi ezinetyhefu ezimbalwa. Nangona kunjalo, ikharbhon diokside esuka kwimizi-mveliso yamandla ebaselwa ngamalahle ayinakuhluzwa. Yigesi yegreenhouse kwaye inegalelo elikhulu kutshintsho lwemozulu.
Ngaba umsi unokuba luncedo?
Ukutshaya yindlela endala kakhulu yokugcina inyama kunye nentlanzi. Ikwatshintsha incasa yoku kutya. Abantu abaninzi bayithanda ngokwenene loo nto.
Abafuyi beenyosi bayalazi iqhinga elikhethekileyo lokuthintela iinyosi ukuba zingalungi: Bathomalalisa amatakane ngomsi. Ukongezelela, kukho ukhuseleko olunikezelwa yimpahla yabo ekhethekileyo.
Imfucuza inokugxotha izinambuzane. Abanye abazingeli basebenzisa umsi ukuze bakhuphe izilwanyana ezinjengeembila neempungutye emingxunyeni ukuze bazibulale.
Iimpawu zomsi zingasetyenziselwa ukuthumela imiyalezo kwimigama emide. Izizwe ezininzi zamaMerika Omthonyama zayisebenzisa le ndlela. Ifana kakhulu nonyulo lukaPopu eVatican. Xa kunyulwa upopu, kuphuma umsi omhlophe. Umsi omnyama ubonisa ukuba indibano ayilungile kwaye iya kukhethwa kwakhona.
KwiiCawa zamaKatolika nezobuOthodoki, kutshiswa isiqhumiso ngezihlandlo ezikhethekileyo ebudeni benkonzo. Ukwenza oku, i-resin yemithi ethile itshiswa kwisitya. Umsi unuka ngamandla kwaye umnandi. AmaYiputa amandulo ayesebenzisa isiqhumiso xa abafileyo bengcwatywa. EBhayibhileni, ithathwa njengenye yezipho zooKumkani abathathu.
Abanye abantu bayawuthanda umsi wecuba kunye neemveliso zecuba ezinxulumene nazo. Kwakhona kukunika imvakalelo entle kangangexesha elithile. Noko ke, umsi uyonakalisa imiphunga namanye amalungu omzimba.
