Aia ʻo Antarctica i ka hemisphere hema, a ua māhelehele ʻia i waena o nā mokuʻāina like ʻole. Ma ka ʻāina o ka ʻāina nui, lawe ʻia ka noiʻi ʻepekema nui, akā ʻaʻole kūpono nā kūlana no ke ola. ʻO ka lepo o ka ʻāina he glaciers mau a me nā wao nahele hau. Ua hoʻokumu ʻia kahi honua kupaianaha o ka flora a me nā holoholona ma aneʻi, akā ʻo ke komo ʻana o ke kanaka i alakaʻi ʻia i nā pilikia kaiapuni.
ʻAlika hoʻoheheʻe
Manaʻo ʻia ʻo ka hoʻoheheʻe Glacier kekahi o nā pilikia kaiaola nui loa ma Antarctica. Loaʻa kēia i ka hoʻomehana honua. Ke piʻi mau nei ka mahana o ka lewa ma ka ʻāina nui. I kekahi mau wahi i ke kau kau he hoʻokaʻawale piha o ka hau. Kuhi kēia i ka ʻoiaʻiʻo o nā holoholona e hoʻopili e ola i nā wā hou a me nā ʻano pae.
Ke hoʻoheheʻe nei ʻo Glaciers me ka kaulike ʻole, hōʻemi iki kekahi mau ʻanaka, ʻoi aku nā mea ʻē aʻe. ʻO kahi laʻana, ua nalowale ka Larsen Glacier i kekahi o kāna nui e like me ka haʻalele ʻana o kekahi mau hau hau iā ia a hele aku i ke kai Weddell.
Puka Ozone ma luna o Antarctica
Aia kekahi puka ozone ma luna o Antarctica. Weliweli kēia ma muli o ka pale ʻole o ka ozone i ka ʻili mai ka pā ʻana o ka lā, ʻoi aku ka wela o ka ea a ʻoi aku ka wikiwiki o ka hoʻomehana honua. Eia kekahi, hāʻawi nā lua ozone i ka hoʻonui ʻana o ka maʻi ʻaʻai, alakaʻi i ka make ʻana o nā holoholona kai a me ka make ʻana o nā mea kanu.
Wahi a nā noiʻi ʻepekema hou loa, ua hoʻomaka iki ka paʻa ʻana o ka lua ozone ma luna o Antarctica, a, e nalowale ana paha i mau makahiki. Inā ʻaʻole e lawe ka poʻe i ka hana e hoʻihoʻi i ka ozone layer, a hoʻomau i ka hāʻawi ʻana i ka haumia i ka lewa, a laila ulu ka lua ozone ma luna o ka pae ʻāina hau.
Pilikia haumia i ke kinoolaola
I ka manawa i kū mua ka poʻe ma ka ʻāina nui, lawe lākou i ka ʻōpala me lākou, a i kēlā me kēia manawa ke haʻalele ka poʻe i kahi nui o nā ʻōpala ma aneʻi. I kēia mau lā, he nui nā kikowaena ʻepekema e hana ma ka ʻāina ʻo Antarctica. Hāʻawi ʻia nā kānaka a me nā lakohana iā lākou e nā ʻano o nā halihali, nā ʻaila a me nā aila wahie e hoʻohaumia i ka meaolaola. Eia kekahi, ke kūkulu ʻia nei nā ʻōpala a me nā ʻōpala holoʻokoʻa ma aneʻi, kahi e pono e hoʻolei ʻia.
ʻAʻole helu ʻia nā pilikia āpau o ka ʻāina anu o ka honua. ʻOiai ʻo ka loaʻa ʻole o nā kūlanakauhale, nā kaʻa, nā hale hana a me ka nui o nā kānaka, nā hana anthropogenic i kēia ʻāpana o ka honua i hana nui i ka pōʻaiapuni.
