Oyendera zachilengedwe omwe akupita ku Antarctica akuwonjezera kutentha kwa dziko komwe kukusungunula madzi oundana a polar, kafukufuku watsopano wapeza.
South Pole yakhala malo otchuka okopa alendo posachedwapa ndi anthu oposa 40,000 openya, kuphatikizapo 7,000 ochokera ku Britain, amafika m'deralo chaka chilichonse. Ambiri amayenda m'sitima zapamadzi kuti akaone madzi oundana ndi nyama zakutchire monga ma penguin.
Koma akuwopedwa kuchuluka kwa "oyendera zachilengedwe akuyambitsa "zowopsa" zowononga mafuta a sitima ndi zinyalala, komanso kusokoneza nyama zakuthengo m'malo amodzi omaliza omwe atsala padziko lapansi.
Wofufuza wachi Dutch, Machiel Lamers, yemwe adatumidwa ndi Netherlands Organisation for Scientific Research kuti afufuze momwe chilengedwe chimakhudzira kuchuluka kwa zokopa alendo m'dera la polar, adati zitha kupangitsa kuti kutentha kwa dziko kuipire kwambiri.
Iye anati: “Alendo odzafika kudera lokutidwa ndi chipale chofewa akuika pachiwopsezo osati dera la Antarctic lokha chifukwa cha zochita zawo, komanso padziko lonse lapansi.
“Alendo oyendera zachilengedwe okwana 40,000 amene amapita ku South Pole chaka chilichonse amatulutsa mpweya woipa kwambiri.
"Zokopa alendo ndizochita bwino kwambiri ku Antarctica. Kumene, zaka 20 chabe kapena kuposapo zapitazo, odzaona malo oŵerengeka okha mazana angapo ananyamuka kuloŵera ku South Pole, anthu oposa 40,000 ochita chidwi anayenda kum’mwera kwenikweni kwa Dziko Lapansi nyengo yachisanu yatha.”
Ulendo wa milungu iwiri ku Antarctic pano umawononga pafupifupi £3,500.
A Lamers adati phindu la zokopa alendo ku Antarctic liyenera kukhala logwirizana ndi momwe chilengedwe chimakhudzira chilengedwe.
"Ngakhale kuti zokopa alendo zili ndi zabwino zambiri zomwe zingapereke ku South Pole, kuchuluka kwa anthu kumayambitsa kuipitsa koopsa," adatero.
"Madera akumaloko akukumana ndi mavuto, zombo zokulirapo zikupita kumeneko, alendo akuyang'ana nthawi zonse 'zamphamvu, zachangu, zochulukira' ndipo palibe amene angasunge zonsezi m'njira yoyenera.
"South Pole imayang'aniridwa ndi mgwirizano wapadziko lonse lapansi, koma palibe amene ali ndiudindo pansi. Palibe ndondomeko yokhazikitsa malire a zokopa alendo.”
Bungwe la International Association of Antarctic Tour Operators lakhazikitsa malamulo okhwima oteteza mbeu ndi tizilombo ndipo lalonjeza kuti lilemekeza chilengedwe.
Komabe a Lamers adati payenera kukhala mgwirizano wapadziko lonse womwe udzachepetse kuchuluka kwa alendo obwera kudzafika ku Antarctica.
Ngakhale kuti Pangano la Antarctic lafuna kuti pakhale malire, izi zikukhudza mayiko 28 okha ndipo akufunika kulimbikitsidwa.
"Zili m'zawo [oyendetsa alendo] kuti asakhale ndi alendo ambiri obwera nthawi imodzi, palibe amene amapita ku Antarctica kukapeza zombo zina zisanu ndi chimodzi za alendo kumeneko," adatero.
“Yakwana nthawi yokhazikitsa malamulo omveka bwino; mapangano osalongosoka sakukwaniranso.”
