Nyanja ya Arctic ndi yaying'ono kwambiri padziko lapansi. Dera lake ndi "kokha" ma kilomita lalikulu 14 miliyoni. Ili kumpoto kwa dziko lapansi ndipo satentha mpaka kusungunuka kwa ayezi. Chipale chofewa nthawi ndi nthawi chimayamba kuyenda, koma sichitha. Zomera ndi zinyama pano, zambiri, sizosiyana kwambiri. Mitundu yambiri ya nsomba, mbalame ndi zinthu zina zamoyo zimawonedwa m'malo ena.

Kukula kwa nyanja

Chifukwa cha nyengo yovuta, Nyanja ya Arctic yakhala ikulephera kufikira anthu kwazaka zambiri. Maulendo adakonzedwa pano, koma ukadaulo sunalole kuti amasinthidwe potumiza kapena zochitika zina.

Kutchulidwa koyamba kwa nyanja iyi kunayamba m'zaka za zana lachisanu BC. Maulendo angapo komanso asayansi ena adatenga nawo gawo pofufuza madera, omwe kwa zaka mazana ambiri adasanthula kapangidwe ka posungira, mafunde, nyanja, zilumba, ndi zina zambiri.

Kuyesera koyamba koyenda m'malo am'nyanja opanda ayezi wamuyaya adapangidwa koyambirira kwa 1600. Zambiri mwazimene zidasokonekera chifukwa cha zombo zomwe zidakumana ndi ayezi wambiri. Chilichonse chinasintha ndikupanga zombo zoopsa. Chombo choyamba chomwe chidamangidwa ku Russia chidatchedwa Payot. Anali sitima yampweya wokhala ndi mawonekedwe apadera a uta, zomwe zidapangitsa kuti zitheke kuphwanya ayezi chifukwa cha kuchuluka kwakukulu kwa chotengera.

Kugwiritsa ntchito zombo zapaulendo zidapangitsa kuti ziyambe kuyendetsa ntchito m'nyanja ya Arctic, njira zoyendera bwino ndikupanga mndandanda wonse wazowopseza chilengedwe choyambirira.

Zinyalala ndi kuipitsa mankhwala

Kufika kwakukulu kwa anthu m'mphepete mwa nyanja ndi ayezi wanyanja kunapangitsa kuti pakhale malo otayira zinyalala. Kuphatikiza pa malo ena m'midzi, zinyalala zimangotayidwa pa ayezi. Imakutidwa ndi chipale chofewa, imazizira kwambiri ndikukhalabe mu ayezi mpaka kalekale.

Chinthu chosiyana pakuwononga nyanja ndi mankhwala osiyanasiyana omwe adawonekera pano chifukwa cha zochita za anthu. Choyamba, awa ndi ngalande zonyansa. Chaka chilichonse, pafupifupi ma cubic metres mamiliyoni khumi osagwiritsidwa ntchito amatulutsidwa m'nyanja kuchokera m'malo osiyanasiyana ankhondo ndi anthu wamba, midzi, ndi malo.

Kwa nthawi yayitali, magombe omwe sanakonzedwe, komanso zilumba zambiri za m'nyanja ya Arctic, adagwiritsidwa ntchito potaya zinyalala zamankhwala osiyanasiyana. Chifukwa chake, apa mutha kupeza ng'oma zamafuta zamafuta omwe agwiritsidwa ntchito, mafuta ndi zina zowopsa. M'nyanja ya Kara, malo okhala ndi zinyalala za nyukiliya amasefukira, ndikuwopseza moyo wonse mkati mwa utali wozungulira makilomita mazana angapo.

Ntchito zachuma

Ntchito zachiwawa komanso zochulukirapo zomwe zimapangitsa kuti mayendedwe azinyamula, malo ankhondo, nsanja zam'migodi mu Arctic Ocean zimabweretsa kusungunuka kwa ayezi komanso kusintha kwa kayendedwe ka kutentha kwa dera. Popeza kuti madzi amtunduwu amakhudza kwambiri nyengo padziko lapansi, zotsatira zake zimakhala zoyipa.

Kugawanika kwa madzi oundana okalamba, phokoso la zombo ndi zina zomwe zimayambitsa matenda zimabweretsa kuwonongeka kwa zikhalidwe ndi kuchepa kwa ziweto zam'deralo - zimbalangondo, zisindikizo, ndi zina zambiri.

Pakadali pano, pamiyeso yosungira Nyanja ya Arctic, International Arctic Council ndi Strategic for Protection of the Arctic Environment, yovomerezedwa ndi mayiko asanu ndi atatu omwe ali ndi malire ndi nyanja, akugwira ntchito. Chikalatacho chidalandiridwa kuti muchepetse kuchuluka kwa anthopogenic posungira ndikuchepetsa zovuta zake ku nyama zamtchire.
