Ngā Pānga o te Huringa Āhuarangi ki ngā Ākau Korara
E kiia ana ngā toka korara ko ngā "ngā ngahere ua o te moana" nā te mea he nui te kanorau o ngā momo koiora me ngā rauropi nui e tautokona ana e rātou. He iti iho i te 1% o te papa moana te rahi, ā, neke atu i te 25% o ngā momo moana katoa kei roto, tae atu ki ngā ika, ngā mokomoko, me te maha atu o ngā mea ora o te moana. Heoi, kei te mōrearea haere ēnei rauropi oraora i raro i te wai i te huringa āhuarangi, he āhuatanga ā-ao e puta ai ngā huringa nui ki te pūnaha āhuarangi o te Ao. He hohonu, he maha ngā āhuatanga, ā, kāore pea e taea te whakakore.
Te Whakamākūkū i te Korara: Te Tūkino Matua
Ko tētahi o ngā pānga tino kitea, tino tuhia hoki o te huringa āhuarangi ki ngā toka ko te mā o te toka. He hononga tahi tō ngā toka me ngā rimurimu moroiti e kiia nei ko ngā zooxanthellae, e noho ana i roto i ō rātou kiko. Mā ēnei rimurimu ka hoatu ki ngā toka ō rātou tae kanapa, ā, ko te mea nui ake, tae atu ki te 90% o ō rātou pūngao mā te photosynthesis.
Ina piki ake te pāmahana o te wai moana ki tua atu i ngā taumata e manawanuihia ana e ngā korara, ahakoa he 1–2°C noa iho i runga ake i te mōrahi toharite o te raumati, ka uaua haere tēnei hononga. Ka panaia e ngā korara taumaha ngā zooxanthellae, ka ngaro te tae, ā, ka puta he āhuatanga e mōhiotia ana ko te mā o te korara. Ahakoa kāore ngā korara kua mā e mate tonu, kei roto rātou i te āhua ngoikore, ā, he ngāwari ake ki te pāngia e te mate, te ngoikore o te kaha whakaputa uri, me te mate mēnā ka mau tonu ngā āhuatanga taumaha.
Kua kitea te maha o ngā whakapakeketanga nui o te moana i ngā tekau tau kua pahure ake nei, me te piki haere o te auau me te kaha o te pānga. Hei tauira, kua maha ngā whakapakeketanga nui o te moana i te Great Barrier Reef, te pūnaha toka korara nui rawa atu o te ao, inā koa i te tau 1998, 2002, 2016, me te 2017, ā, i hua ake ai te pakaru, te whakangaromanga rānei o ētahi wāhanga nui o te toka.
Te Whakanui Moana
Ko tētahi atu āhuatanga nui o te huringa āhuarangi e pā ana ki ngā toka korara ko te waikawa o te moana. I te pikinga ake o ngā taumata CO2 o te āhuarangi nā ngā mahi a te tangata pēnei i te tahu hinu pūmua, ka mimitihia e ngā moana te wāhanga nui o tēnei CO2. Ina rewa te CO2 ki roto i te wai moana, ka puta he waikawa waro, ka whakaheke i te pH o te wai, ka nui ake te waikawa.
Ka whakawhirinaki ngā toka korari ki tētahi tukanga e kiia nei ko te whakapūkara hei hanga i ō rātou angaanga mai i te konupūmā kāponāte. Ka whakararuraru te waikawa nui ake i tēnei tukanga, ka uaua ake ai mā ngā toka te whakaputa me te pupuri i ō rātou angaanga. Ehara i te mea ka ngoikore noa iho te hanganga ā-tinana o ngā toka korari, engari ka pāngia hoki te hauora whānui me te tere tipu o ngā hapori toka korari.
Te Pikinga o te Taumata Moana me te Horo o te Takutai
Ko te pikinga o te taumata o te moana tētahi atu hua o te mahana o te ao, e ahu mai ana i te rewa o ngā taupoki hukapapa me te whānui o te wai moana. Ka taea e ngā taumata moana teitei ake te arahi ki te pikinga o te oneone me te pōuri huri noa i ngā toka korara, ka taea e ēnei te ārai i ngā korara me te whakaiti i te nui o te hihi o te rā e tae atu ana ki a rātou, he mea nui mō te photosynthesis e ā rātou rimurimu mahi tahi.
Hei tāpiri atu ki tēnā, me te pikinga ake o te taumata o te moana, ka piki ake te kaha o ngā ngaru, ka nui ake te horo o te takutai moana, ā, ka taea hoki te whakangaro ā-tinana i ngā hanganga o te toka korara. He tino whakaraerae ngā moutere me ngā motu iti o te toka korara ki ēnei huringa, e whakatuma ana i ngā pūnaha rauropi me ngā hapori tangata e whakawhirinaki ana ki a rātou mō te tiaki me ngā rauemi.
Te Hurihanga o ngā Tauira o te Huarere me te Kaha o te Tupuhi
E pā ana hoki te huringa āhuarangi ki ngā panonitanga o ngā tauira huarere, tae atu ki te pikinga ake o te kaha me te auau o ngā āhuatanga huarere tino kino pērā i ngā awhiowhio me ngā porowhita. Ka taea e ēnei awhiowhio kaha te whakangaro tinana i ngā toka mā roto i ngā ngaru kaha me ngā ngaru nui, ka pakaru ngā hanganga korara, ā, ka ngaro te nohoanga mō te maha o ngā momo moana.
Hei tāpiritanga, ka pāngia ngā toka korara e ngā panonitanga o te ua. Mā te nui haere o te ua me te rerenga wai ka piki ake te taumata o te oneone, ngā matūkai, me ngā poke e uru ana ki ngā wai takutai. Ka hua ake pea tēnei i te puāwaitanga o te rimurimu, ka kaha ake te whakataetae a ngā toka korara ki te mārama me te wāhi, ā, ka heke te kounga o te wai, ka nui ake te taumahatanga o ngā toka korara.
Te Whakangaromanga o te Pūnaha Rauropi me te Ngaronga o te Kanorau Koiora
Kāore ngā pānga o te huringa āhuarangi ki ngā ākau korara e herea noa ki ngā korara engari ka horapa puta noa i te pūnaha rauropi katoa. He maha ngā momo mea ora o te moana e tautokona ana e ngā ākau korara, tae atu ki ngā ika, ngā invertebrate, me ētahi atu rauropi e whakawhirinaki ana ki te hanganga o te ākau hei kai, hei piringa, hei wāhi whakaputa uri.
I te hekenga o ngā toka korari nā te mā, te waikawa, me te kino ā-tinana mai i ngā awha, ka pāngia hoki ēnei momo e whakawhirinaki ana ki a rātou. Ka taea e tēnei te arahi ki ngā pānga heke puta noa i te whatunga kai moana, ā, ka mutu, ka whakaitihia te kanorau koiora me te whakarerekē i te taurite o ngā pūnaha rauropi moana. Ka pāngia hoki ngā hapori tangata e whakawhirinaki ana ki a rātou mō te oranga mā te hī ika, te tūruhi, me te tiaki takutai.
Ngā Mahi Whakaiti me te Tiaki
Me whai huarahi maha ngā huarahi hei whakatika i ngā tūmomo mōrearea e pā mai ana i te huringa āhuarangi ki ngā toka korara. Me arotahi ngā mahi whakaiti i te pāmahana ki te whakaiti i ngā tukunga hau kati kōtuhi hei whakawhāiti i te mahana o te ao me ōna pānga e pā ana. Kei roto i tēnei ko te neke ki ngā pūtake pūngao hou, te whakapai ake i te whai huatanga o te pūngao, me te whakatinana i ngā kaupapa here hei whakaiti i ngā tapuwae waro.
Haunga ngā mahi whakaiti i te taiao o te ao, he mea nui ngā mahi tiaki ā-rohe. Tērā pea ka uru atu ki tēnei te tiaki i ngā rohe ākau mai i te hī ika nui rawa, te parahanga, me ētahi atu pānga tika a te tangata. Ka taea te whakatū i ngā Rohe Tiaki Moana (MPA) hei whakarato i ngā piringa haumaru mō ngā ākau me ōna momo e pā ana, kia taea ai e ngā pūnaha rauropi te ora me te tupu.
Kei te tūhuratia hoki ngā huarahi auaha pēnei i te māra korara me te whanaketanga āwhina. Ko te māra korara ko te whakatipu i ngā kongakonga korara i roto i ngā whare whakatipu me te whakatō anō ki runga i ngā toka kua pakaru. Ko te whāinga o te whanaketanga āwhina he whakarei ake i te pakari o ngā korara ki te huringa āhuarangi mā te whakatipu uri whiriwhiri, te whakarerekētanga ira rānei.
Opaniraa
He tūmomo mōrearea te huringa āhuarangi ki ngā toka korara o te ao katoa. Ko ngā pānga o te pikinga o te pāmahana o te moana, te waikawa o te moana, te pikinga o te taumata o te moana, me ngā huringa o te āhuarangi kei te whakararu nui i ēnei pūnaha rauropi nui. Ko te ngaronga o ngā toka korara ehara i te mea he aituā taiao anake, engari he pānga nui ki te ōhanga me te pāpori mō ngā miriona tāngata e whakawhirinaki ana ki a rātou.
Hei whakamutunga, ko te oranga tonutanga o ngā toka korara e whakawhirinaki ana ki tō tātou kaha ki te whakaiti i te huringa āhuarangi me te whakatinana i ngā rautaki tiaki whai hua. Ko te wā tēnei hei mahi, i te mea kei te tere kati te matapihi o te whai wāhitanga ki te whakaora i ēnei pūnaha rauropi tino nui. Mā te aro atu ki ngā pūtake o te huringa āhuarangi me te mahi i ngā mahi matatau ki te tiaki me te whakaora i ngā toka korara, ka taea e tātou te whakarite kia whai hua tonu ngā reanga o muri mai i te kanorau koiora whakamiharo me ngā ratonga pūnaha rauropi e whakaratohia ana e rātou.
