Te Pānga o te Keri ki te Kounga o te Wai
He rāngai ōhanga nui te keri maina mō te maha o ngā whenua, tae atu ki Initonīhia. I te maha o ngā wāhi, he poutokomanawa nui te keri maina, e whakarato ana i ngā mahi me te whakapiki ake i te moni whiwhi ā-rohe me te motu. Heoi, he maha ngā pānga nui ki te taiao o ngā mahi keri maina, tae atu ki te kounga o te wai. Ka matapakihia e tēnei tuhinga te pānga o ngā mahi keri maina ki te kounga o te wai, tae atu ki ngā pānga me ngā otinga.
Ngā Momo Keri me ō rātou Pānga ki te Wai
He maha ngā momo keri, pērā i te waro, te koura, te nikara, te tine, me ētahi atu, he pānga motuhake tō ia momo ki te wai. Hei tauira, he maha ngā wā ka pāngia te wai e te keri waro nā te mimiti waikawa o te maina, engari ko te keri koura, mā te whakamahi i te mercury, ka taea te whakaputa wai kua poke i ngā konganuku taumaha.
Te Wairewa o te Maina Waikawa
Ko tētahi o ngā raruraru matua o te keri ko te rerenga wai waikawa o te maina (AMD). Ka puta te AMD ina tauhohe te wai me te hāora ki ngā toka kei roto ngā kohuke whanariki, pērā i te pyrite, ka puta he waikawa whanariki, ā, ka whakarewahia ngā konganuku taumaha mai i ngā toka. He maha ngā wā ka poke ngā awa, ngā roto, me te oneone i te rerenga wai AMD, ka kino ai ngā pūnaha rauropi wai me te ngaronga o te kanorau koiora.
Te Whakamahinga o ngā Matū Morearea
Ka whakamahia e ngā maina koura te mercury me te cyanide hei wehe i te koura mai i ōna konganuku. He tino paitini ngā matū e rua, ā, he uaua ki te wawahi i roto i te taiao. Ka taea e te mercury e uru ana ki ngā wai te kino i te pūnaha io matua, me te whakararu i te hauora o te tangata, ā, ka taea e te cyanide te whakamate i ngā rauropi wai.
Te Pikinga o te Parataiao
Ko te nuinga o ngā mahi keri he tango i te nui o te oneone me te toka. Ka hua ake pea tēnei i te nui o te paru i roto i ngā awa me ngā wai e karapoti ana. Ka taea e te paru nui te whakaiti i te kounga o te wai mā te whakanui ake i te paru, te whakaiti i ngā taumata hāora rewa, me te pā ki ngā mea ora i roto i te wai.
Te Pānga o te Keri ki ngā Pūnaha Rauropi Wai
Ehara i te mea he kino noa iho te pānga o te keri maina ki te kounga o te wai, engari he kino anō hoki ki ngā rauropi wai. He maha ngā pānga me mōhio tātou ki:
Te Ngaronga o te Koiora
He wāhi noho kino pea te wai kua poke i te rerenga waikawa o ngā maina, i ngā konganuku taumaha rānei, mō te nuinga o ngā mea ora. He maha ngā wā kāore e taea e ngā ika, ngā manu me ētahi atu kararehe wai te ora i roto i te wai kua poke, ā, ka ngaro te kanorau koiora.
Te Whakangaromanga o te Mekameka Kai
Ka taea hoki e te parahanga wai te whakararuraru i te mekameka kai i roto i ngā pūnaha rauropi wai. Ka mate pea ngā mea ora iti pēnei i te plankton, e mahi ana hei kai mā ngā ika me ngā mea ora nunui, nā te nui o te paitini wai. Ka pā tēnei ki te mekameka kai katoa, ā, i te mutunga ka pā ki te tangata e kai ana i ngā ika, i ētahi atu hua rānei mai i te wai parahanga.
Te Whakangaromanga Nohoanga
Ka taea e te nui rawa o te oneone i puta mai i te keri whenua te kapi i ngā papa o ngā awa me ngā roto, ka kino ai ngā nohoanga o ngā momo rauropi wai. Ka pā pea tēnei ki tā rātou whakaputa uri, ki te rapu kai, me ētahi atu mahi nui.
Pānga ki te Hauora Tangata
He pānga tika anō hoki tō te kounga wai kino e puta mai ana i ngā mahi keri ki te hauora o te tangata. Ko te wai kua poke i ngā konganuku taumaha, pērā i te mercury, te arsenic, me te mata, ka pā mai pea ngā mate kino pērā i te mate pukupuku, te kino o ngā whekau, ngā mate pūnaha io, me te whakaroa i te whanaketanga o ngā tamariki.
Ngā Mate i Puta Mai i ngā Konganuku Taumaha
Ka taea e te nui o ngā konganuku taumaha i roto i te wai te whakararu i te tangata i ngā mate pūmau. Hei tauira, ko te konukōre e kohia ana i roto i te tinana tangata ka taea te whakararu i ngā io me te paihana. Waihoki, ko te nui rawa o te āhenike i roto i te wai ka taea te whakararu i te mate pukupuku kiri, pukahukahu, me te pūkahukahu.
Ngā mate pāwera
Ka taea hoki e te parahanga wai te horapa o ngā mate pipiri. Ka taea e ngā huakita me ētahi atu mate urutā te tere tipu i roto i te wai poke, ka pangia ngā taupori huri noa e whakamahi ana i te wai mō te inu, te kaukau, me ētahi atu mahi o ia rā.
Te Whakatika i te Pānga o te Keri ki te Kounga o te Wai
Ko te aro atu ki ngā pānga o te keri maina ki te kounga o te wai me whai huarahi whānui, whānui hoki. Ko ngā huarahi pea ko ngā kaupapa here a te kāwanatanga, te whakamahi i ngā hangarau e pai ana ki te taiao, me te whai wāhi a te hapori.
Ngā Kaupapahere me ngā Ture
He mahi nui tā te kāwanatanga ki te whakahaere me te aroturuki i ngā mahi keri. Me tino kaha ngā ture hei whakarite kia tutuki ngā kamupene keri i ngā paerewa taiao kua whakaritea, kia whakahaerehia ngā aromatawai pānga taiao i mua i te tīmatanga o ngā mahi, me te tāuta i ngā hangarau hei whakaiti i ngā pānga kino ki te wai.
Hangarau Hoa Taiao
Ko te whakamahi i ngā hangarau e pai ana ki te taiao i roto i ngā mahi keri tētahi otinga hei whakaiti i ngā pānga kino ki te kounga o te wai. Hei tauira, mā te hangarau hei rongoā i ngā wai para keri i mua i te tukunga ki te taiao ka taea te whakaiti i ngā taumata o ngā poke me ngā konganuku taumaha i roto i te wai.
Te Whakaora me te Whakaora
Ko te whāinga o ngā mahi whakaora maina he whakaora i te whenua me ngā wai kua whakararuraruhia e ngā mahi maina. Kei roto i tēnei tukanga ko te whakatō anō i ngā tipu o te rohe, te hanga i ngā nohoanga, me te whakaora i ngā rere o te wai. Mā te whakaora tika ka āwhina i te whakaora i te mahi a te pūnaha rauropi me te whakapai ake i te kounga o te wai.
Mātauranga Hapori me te Whai Wāhitanga
He mea nui anō hoki te whai wāhi kaha o te hapori ki te pupuri me te whakapai ake i te kounga o te wai. Me whakaako ngā hapori ki ngā pānga o te keri maina ki te wai, me te akiaki hoki kia whai wāhi atu ki ngā mahi tiaki taiao, pērā i ngā kaupapa aroturuki kounga wai me ngā mahi horoi taiao.
Whakamutunga
He nui te takoha o te mahi keri whenua ki te taha ōhanga, engari he nui anō hoki ōna pānga ki te kounga o te wai. Kei roto i ēnei pānga ko te rerenga wai waikawa o te maina, te whakamahinga o ngā matū kino, me te pikinga o te paru, e pā ana ki ngā mea ora o te wai me te hauora o te tangata. Me mahi tahi te kāwanatanga, te ahumahi, me te hapori ki te whakatinana i ngā kaupapa here pakari, te whakamahi i ngā hangarau e pai ana ki te taiao, te whakahaere i te whakaora whenua, me te whakanui ake i te mātauranga me te whai wāhi a te marea ki te tiaki wai. Mā te huarahi whānui, e tumanakohia ana ka taea te whakaiti i ngā pānga kino o te keri whenua ki te kounga o te wai, ā, mā reira ka tiakina he taiao hauora, he taiao pumau hoki mō ngā whakatipuranga o muri mai.
