Isithombe sihle, akunjalo? Nakuba kungase kubonakale kunjalo, akuthintwa kabusha nge-Photoshop nanoma yiluphi olunye uhlelo lokuhlela isithombe, kodwa kungokwangempela. Iqhwa alihlali limhlophe, lingase libe bomvu, nakuba kubantu baseMelika lithatha umbala ojwayelekile wekhabe, yingakho laziwa ngokuthi iqabunga lekhabe, isenzakalo semvelo esithakazelisayo esihlobene iqhwa elipinki.
Kodwa, Yini ebangela ukuthi ibe nalo mbala?
Ngokusobala, kukhona i-algae eluhlaza okwesibhakabhaka encane ogama lakhe lesayensi ngu I-Chlamydomonas nivalis lokho ube nombala obomvu emvilophini yabo ye-gelatinous ebavikela emisebeni ye-ultraviolet yezindawo ezipholile. Ngokufika kwentwasahlobo banda ngokushesha okukhulu, okwenza indawo emhlophe ibe nombala obomvana omuhle kakhulu noma obomvu, into ehlobene .
Ukubona iqhwa lekhabe, ungaya kunoma yisiphi isifunda se-polar, kodwa kunconywa kakhulu ukuya endaweni ISierra Nevada yaseCalifornia (USA). Minyaka yonke, iziqongo zayo zidaywa ngalo mbala ogqamile. Uma ungathanda ukufunda okwengeziwe ngalesi simo, ungafunda mayelana ilukuluku mayelana neqhwa kanye nobudlelwano bayo neqhwa lekhabe.
Nakuba ishiya izindawo zayo zihlaba umxhwele, iqiniso elidabukisayo liwukuthi njengoba iplanethi ifudumala, i- ulwelwe luyazalana kalula kakhudlwana. Ngokwenza kanjalo, bavimbela iqhwa elimhlophe ekuboniseni ukukhanya kwelanga, ngesivinini a 13% inqubo yokuncibilika kweqhwa, njengoba kwembulwe ucwaningo olwenziwa yiqembu lososayensi abavela e-German Research Center for Geosciences in Potsdam kanye ne-University of Leeds (UK), eyanyatheliswa kumagazini wesayensi. Nature.
Ungafunda isifundo esigcwele lapha (ngesiNgisi).
Yini engenziwa ukuze kulondolozwe iqhwa elimhlophe?
Amazinga okushisa aphezulu kanye nokwanda kwe I-Chlamydomonas nivalis kungaba nemiphumela elimazayo ku-ecosystem, kubangele a umphumela we-chain ezinhlotsheni ezincike eqhweni naseqhweni njengendawo yokuhlala. Kubalulekile ukwenza izinyathelo ezisiza ukunciphisa ukushisa komhlaba, njenge:
- Khuthaza ukusetshenziswa kwamandla avuselelekayo esikhundleni sezinto zokubasa ezimbiwa phansi.
- Ukunciphisa i-carbon footprint ngokugqugquzela ezokuthutha ezisimeme.
- Sebenzisa izinqubomgomo zokongiwa kwemvelo ezindaweni ezishisayo nezinezintaba.
- Ukuqwashisa umphakathi ngokubaluleka kokuvikela imvelo kanye nemvelo esengozini.
Isimo seqhwa lekhabe akusona sodwa esithathe ukunaka kososayensi. Kunamanye amacala athakazelisayo, afana nalawa:
- Imvula ebomvu: Kwenzeka lapho iziphepho ziletha uthuli noma isihlabathi ezindaweni eziwugwadule, ezihlangana namanzi futhi kubangele imvula ebomvu, into ongafunda kabanzi ngayo yini imvula ebomvu.
- Iqhwa Legazi: Isimanga lapho i-meltwater evela eziqhweni zeqhwa ithatha umbala obomvu ngenxa yokuqhakaza kwe-algae namagciwane emanzini. Ukuze ujule kulesi sihloko, ungathintana iqhwa legazi.
- I-Northern Lights: Nakuba zingahlobene ngokuqondile, lezi zibani esibhakabhakeni se-polar zingabonakala ezindaweni lapho iqhwa lekhabe lenzeka khona, futhi libangelwa ukuxhumana komoya welanga nensimu kazibuthe Yomhlaba.
Iqhwa lekhabe liyinto yemvelo ethakazelisayo, nakuba ibukeka kahle, inesexwayiso esibalulekile mayelana nomthelela wokuguquka kwesimo sezulu. Ukuqonda ukusebenzisana kolwelwe neqhwa akubalulekile nje kuphela kwisayensi, kodwa futhi kusisiza ukuba sazise ubunkimbinkimbi beplanethi yethu futhi sithathe izinyathelo zokuyivikela.
Ngakho-ke, ngokuzayo lapho ubona iqhwa lekhabe, cabanga ngobuhle balo besikhashana nokuthi limelelani ngomhlaba wethu. Ukulondolozwa kwalezi zimo eziyingqayizivele kufanele kube yinto eza kuqala ezizukulwaneni ezizayo.
