Isingeniso
Wake wazibuza ukuthi kwenzekani emzimbeni wakho uma uhogela i-carbon dioxide (CO2) eningi? I-CO2 iyigesi evamile ekuphileni kwethu kwansuku zonke, ekhiqizwa hhayi kuphela ngesikhathi sokuphefumula kodwa futhi kusukela ezinqubweni ezihlukahlukene zomlilo. Nakuba i-CO2 idlala indima ebalulekile emvelweni, ukugxila kwayo okuphezulu kungadala izingozi zempilo. Lesi sihloko sihlola ukuthi ingabe i-CO2 iyingozi yini kubantu, ngaphansi kwaziphi izimo engase ibeke impilo engozini, nezimiso zesayensi nobungozi bezempilo obuhilelekile.
Iyini i-Carbon Dioxide?
I-Carbon dioxid e iyingxenye ebalulekile yenqubo yokuphefumula futhi idlala indima ebalulekile ku-photosynthesis yezitshalo. Kunemithombo emibili eyinhloko ye-CO2: imithombo yemvelo, njengokuphefumula kwezitshalo nezilwane kanye nemisebenzi yentaba-mlilo, kanye nemithombo eyenziwe ngabantu, okuhlanganisa ukushiswa kwezinto zokubasa ezimbiwa phansi kanye nokukhishwa kwezimboni.
Njengoba imisebenzi yabantu ikhula, ukukhishwa kwe-CO2 kukhuphuka kancane kancane, okunomthelela omkhulu ekukhuphukeni kwezinga lokushisa emhlabeni jikelele. Ukushintsha kwesimo sezulu, okuqhutshwa umphumela we-greenhouse, kubhebhetheka ngokukhuphuka kwamazinga e-CO2. Lokhu kwanda okusheshayo kwe-CO2 akuthinti nje imvelo kuphela kodwa futhi kubangela izingozi zempilo ezingaba khona.
Umthelela weCarbon Dioxide empilweni yomuntu
Ngaphansi kwezimo ezijwayelekile, ukugxila kwe-CO2 emkhathini nangaphakathi komzimba akubeki usongo lwezempilo. I-CO2 iyadingeka ukuze uphefumule, futhi wonke umuntu ukhiqiza futhi akhiphe i-CO2 ngokwemvelo ngesikhathi sokuphefumula. Ukugxiliswa okujwayelekile komkhathi we-CO2 cishe ku-0.04% (400 ppm), okungenangozi. Kodwa-ke, lapho amazinga e-CO2 ekhuphuka ezindaweni ezivalekile, kungaholela ezinkingeni zezempilo. Ukugxila okuphezulu kwe-CO2 kungasusa umoya-mpilo osemoyeni, kubangele isiyezi, ukuphelelwa umoya, ukudideka, ukuguquguquka kwemizwelo, futhi, ezimweni ezimbi kakhulu, ngisho nokuqunjelwa.
Ngaphezu kokungakhululeki ngokomzimba, ukuchayeka isikhathi eside ekugxilweni okuphezulu kwe-CO2 kungathinta imisebenzi yokuqonda. Ucwaningo lubonisa ukuthi amazinga e-CO2 aphakeme angaphazamisa ukunaka, inkumbulo, nokwenza izinqumo. Ezindaweni ezingenawo umoya ohlanzekile, njengamagumbi okufundela noma amahhovisi, ukwanda kwe-CO2 kungaholela ekukhathaleni nobunzima bokugxila, kube nomthelela omubi emsebenzini nokufunda. Ukuchayeka isikhathi eside ku-CO2 ephezulu kuyingozi ikakhulukazi kubantu asebekhulile, izingane, noma labo abanezimo zokuphefumula.
Unganquma Kanjani Uma Amazinga e-CO2 Aphezulu Kakhulu
Izimpawu zobuthi be-CO2 ngokuvamile ziqala ngokungaphatheki kahle futhi ziba zimbi kakhulu njengoba ukugxila kukhuphuka. Izimpawu zakuqala zihlanganisa ubuhlungu bekhanda, isiyezi, nokuphelelwa umoya. Njengoba ukugxila kwanda, izimpawu zingase zikhuphukele ekudidekeni, isicanucanu, ukushaya kwenhliziyo okusheshayo, futhi, ezimweni ezimbi kakhulu, i-coma.
Ukuqapha amazinga we-CO2,CO2umncanesingasetshenziswa. Lawa madivayisi akala ukugxila kwe-CO2 ngesikhathi sangempela futhi aqinisekisa ukuthi ikhwalithi yomoya wasendlini ihlangabezana nezindinganiso zokuphepha. Ngokuvamile, amazinga e-CO2 angaphakathi kufanele ahlale ngaphansi kuka-1000 ppm, futhi ukuchayeka ezindaweni ezinamaleveli e-CO2 angaphezu kuka-2000 ppm kufanele kugwenywe. Uma uzizwa unesiyezi, ungaqiniseki ngokomzwelo, noma ungaphathekile kahle ekamelweni, kungase kubonise amazinga aphezulu e-CO2, futhi ukungena komoya ngokushesha kufanele kuqondiswe.
Izinyathelo Zokunciphisa Ukuchayeka kwe-CO2
Enye indlela esebenzayo yokunciphisa ukuchayeka kwe-CO2 ukuthuthukisa ukujikeleza komoya endlini. Ukungena komoya okuhle kusiza ukunciphisa ukugxila kwe-CO2 futhi kwethule umoya omusha. Ukuvula amafasitela, ukusebenzisa iziphephetha-moya ezikhipha umoya, noma ukuhlola njalo nokugcina izinhlelo zokupholisa umoya zonke kuyizindlela ezinhle zokuthuthukisa umoya. Ezindaweni zasendlini ezinjengamahhovisi, amagumbi okufundela, noma amakhaya, ukuthuthukisa ukugeleza komoya kungavimbela ngempumelelo ukwakheka kwe-CO2.
Ukwengeza, izinto zokuhlanza umoya noma izitshalo zingasiza ukwehlisa amazinga e-CO2. Izitshalo ezithile, njengezitshalo zesicabucabu, iminduze yokuthula, ne-ivy, zimunca kahle i-CO2 futhi zikhulule umoya-mpilo. Kuhlanganiswe nezinye izindlela zokungenisa umoya, zingathuthukisa izinga lomoya.
Okokugcina, ukuthuthukisa imikhuba elula kunganciphisa kakhulu ukuchayeka kwe-CO2. Isibonelo, ukuvula njalo amafasitela ukuze kungene umoya, ukugwema ukuminyana endlini, nokusebenzisa amafeni okujikeleza komoya kuyizindlela ezisebenzayo zokugcina umoya omusha wangaphakathi.
Isiphetho
Ukuqonda umthelela we-CO2 empilweni kubalulekile, njengoba kuthinta kokubili inhlalakahle yomuntu kanye nokusimama kwemvelo. Nakuba ukugxilisa okujwayelekile kwe-CO2 kungelona usongo, amazinga adlulele ezindaweni ezivalekile angaholela ezinkingeni zempilo ezifana nokukhubazeka kokusebenza kwengqondo kanye nobunzima bokuphefumula.
Ngokunaka ikhwalithi yomoya wasendlini, ukuthatha izinyathelo ezisebenzayo zokungenisa umoya, ukusebenzisa izinto zokuhlanza umoya, nokuthatha imikhuba emihle, singanciphisa ukuchayeka kwe-CO2 futhi sihlale sinempilo. Wonke umuntu kufanele asebenze ngokuzimisela ukuze athuthukise izinga lomoya elibazungezile ukuze kuncishiswe izinsongo zezempilo ezingase zibe khona ngenxa ye-CO2.
Ukukhuthaza impilo yekhabhoni ephansi, ukwenza ngcono ukusebenza kahle kwamandla, ukuthuthukisa izinsiza ezivuselelekayo, ukuthuthukisa izinhlelo zokuhamba, ukunciphisa ukukhishwa kwekhabhoni, ukusebenzisa imikhiqizo eyonga amandla, ukwandisa ukumbozwa kwezitshalo, ukukhetha izithuthi zomphakathi, ukunciphisa imfucuza, ukugaywa kabusha, kanye nokubambisana kungasiza ekudaleniindawo yokuhlala neyokusebenzela eluhlaza nenempilo.
