Ko ngā ara ārahi māpere he tohu mō te whakamahinga o ngā tukanga whenua o te taiao mō te hangarau tika. I hangaia mai i ngā kohuke pēnei i te plagioclase, te olivine, me te biotite, ka roa te koroheketanga tūturu o ēnei wāhanga i raro i te whenua mō ngā miriona tau, ka hua ake he rauemi tino pai te hanganga. Ehara i te mea he ātaahua noa iho te kanapa pango motuhake me te kakano ōrite - he tohu tirohanga hoki mō te pumau o roto e mea nui ai ēnei ara i roto i ngā taiao hanga tika.
I roto i tā rātou mahi matua, e rua ngā mahi nui a ngā ara ārahi māpere: te tautoko i ngā wāhanga mīhini taumaha me te pupuri tonu i ngā ara nekehanga rārangi tika. I roto i ngā whare hanga puta noa i te ao, ka āta whakarite ēnei ara kia neke ngā taputapu tapahi, ngā taputapu ine, me ngā karetao huihuinga me te tika o te taumata micron ahakoa i raro i ngā kawenga rerekē. Ko te mea e whakamiharo ai tēnei mahi ko te āhua o tōna putanga mai i ngā āhuatanga ā-roto o te rauemi kaua i ngā pūnaha whakatikatika mīhini uaua.
Ko ngā whakaritenga hoahoa mō ēnei wāhanga ahumahi e whakaata ana i ngā tekau tau o te whakatikatika hangarau. Ko te tika o te ārahi he mea nui tonu—ko ngā ātete hanga hou e hiahia ana kia mau tonu te tika o ngā wāhanga neke i roto i ngā mano hauwhā o te inihi puta noa i te roa o te reriwe katoa. Me mau tonu tēnei tika i roto i te mahi tonu, koia te take e aro nuihia ai te ātete kakahu i te wā o te tukanga whakaoti. Ka arotauhia e ngā kaihangarau te pakeke o te mata mā te oro whakahaere me te whakarite kia whakatairangahia te kakano moroiti i te pupuri hinu.
Ko te pumau o te taiao he wero hangarau anō e arohia ana e ngā rēri māpere. Kāore i rite ki ngā momo konganuku e whānui haere ana i te piki me te heke o te pāmahana, ka whakaratohia e te hanganga kohuke o te māpere te ātete wera tūturu. He mea tino nui tēnei āhuatanga i roto i ngā whare e whakaputa ana ngā tukanga miihini i te wera ā-rohe, e pāngia rānei ngā āhuatanga o te taiao e ngā huringa āhuarangi o te wā. Waihoki, ko te pakari o te rauemi ka whakakore i te hiahia mō ngā hanganga tautoko uaua, nā te mea ka taea e te wāhanga rēri kotahi te tu atu i ngā kawenga nui me te kore e piko.
Mā ngā whakaaro hangahanga e whakataurite ēnei whakaritenga mahi me ngā hiahia whakaputa mahi. Ahakoa e hiahiatia ana he taputapu tapahi motuhake mō te rauemi mata, mā te ōritetanga taiao o te māpere ka taea te whakaputa hua miihini ōrite puta noa i ngā mahi whakaputa. Ka whai hua ngā tukanga huihuinga mai i te pumau o ngā āhuatanga o te rauemi—ina oti te huri tika, ka mau tonu ngā āhuatanga kua whakaritea o ngā reera māpere puta noa i te roanga o te wā mahi, he rerekē ki ngā mea whakarewa e hiahia ana kia whakahoutia i ia wā.
Ka horapa ngā whakamahinga o ēnei wāhanga kōhatu hangarau ki ngā ahumahi kanorau. I roto i ngā whare hanga motuka, ka ārahihia e rātou ngā ringa whakarewa karetao me te tino tika. Ka whakanuia e ngā whare hinu matū tō rātou ātete ki te waikura ina whakanohohia ngā taputapu tauira ki ngā taiao uaua. Ka whakawhirinaki ngā whare whakaputa hiko ki tō rātou pumau mō te huihuinga me te tiaki i ngā tāhū. Ahakoa i roto i te hanga kakahu, ka whakarite ngā reera māpere i te kaha o te kakahu i te wā e raranga ana.
Ko te mea e tino wehewehe ana i ngā ara ārahi māpere mai i ngā rauemi kē atu ko te āhua o tā rātou whakatinanatanga i te hononga o te pumau whenua me te tika o te hangarau. Kei roto i ia ara he miriona tau o te hanganga taiao, kua whakatikatikaina mā roto i ngā tikanga hanga hou hei whakatutuki i ngā hiahia o te whakaputanga o te rautau 21. I te mea kei te heke haere tonu ngā ātete hanga me te kaha haere o ngā ture taiao, ko ngā āhuatanga ahurei o ēnei wāhanga kōhatu-taiao e whakanoho ana i a rātou hei otinga pumau mō te whakahaere nekehanga tika e hono ana i ngā tukanga whenua tawhito me ngā tono ahumahi hou.
Mō ngā kaihangarau me ngā kaiwhakahaere whare e arotake ana i ngā otinga whakahaere nekehanga, ka tukuna e ngā ara ārahi māpere he huinga whakamīharo o ngā āhuatanga mahi e uaua ana ki te whakataurite ki ngā momo hangai. Nā tō rātou kaha ki te pupuri i te tika puta noa i ngā tekau tau o te ratonga, te ātete ki te pirau o te taiao, me te mahi me te kore he tikanga tiaki uaua ka waiho hei hangarau tūāpapa i roto i ngā taiao hanga tika puta noa i te ao. I a ngā ahumahi e haere tonu ana ki te pana i ngā rohe o ngā mea ka taea i roto i te hangarau tika, ka noho tonu ēnei wāhanga kōhatu-taiao ki mua i te auahatanga hanga.
