I roto i ngā ahumahi e whakamahia ana ngā matū kaha, te haumākū nui, te wai tote rānei, ka nui ake te pakari o ngā rauemi i te mea hei whiringa noa iho—ka noho hei mea nui. Mai i ngā whare tukatuka waipara ki ngā taputapu keri i waho o te moana, ko ngā mekameka kowiri tira te rārangi tuatahi o te parepare ki te pakaru o te pūnaha i roto i ngā taiao waikura.

Engari me pēhea te mahi tikamekameka kowiri tirae tū atu ana i ēnei taiao uaua? Ka tūhuratia e tēnei tuhinga ngā painga o te hangarau, te pūtaiao rauemi, me ngā rautaki tiaki kei muri i tā rātou mahi whakamiharo.

I hangaia mō te ātete ki te waikura

Ko te painga nui o ngā mekameka kowiri tira ko tōna ātete tino pai ki te waikura. Kāore i rite ki te maitai waro, ki ngā mea kē atu rānei i hangaia ki te konukōre, kei roto i te kowiri tira te chromium, e tauhohe ana ki te hāora i roto i te taiao hei hanga i tētahi paparanga waikura e whakaora ana i a ia anō i runga i te mata. Ka ārai tēnei paparanga i te waikura me te pirau ahakoa ka pāngia te mekameka e ngā matū, te tote, te makuku rānei.

I roto i ngā taiao tino kaha - pērā i ngā whare tukatuka matū, i ngā whare hanga takutai rānei - he mea nui tēnei ārai tiaki. Mā tēnei ka mau tonu te pono o te mekameka me te pono o te mahi i roto i te wā.

Ngā Māka e ōrite ana ki te Taiao

Kāore e rite te hanganga o ngā maitai kore waikura katoa, ā, mā te whiriwhiri i te koranu tika ka nui te rerekētanga o te mahi. Hei tauira:

He pai te ātete o te maitai kore waikura 304 ki te waikura, ā, he pai mō te nuinga o ngā mahi o roto, o waho hoki e waikura paku ana.

He kowiri tira 316, he mea whakarei ake ki te molybdenum, ka whakarato i te parenga pai rawa atu ki ngā hauota me ngā taiao waikawa—he mea tino pai mō te whakamahinga moana, matū rānei.

Mā te mōhio ki te momo e tika ana mō tō taiao mahi ka roa ake te ora o ō mekameka maitai kore waikura, ka whakaiti hoki i te utu nui o ngā whakakapinga.

Te Kaha Mīhini i raro i te Pēhanga

Ehara i te mea ka whakakino noa ngā rauemi e ngā taiao waikura—he maha tonu ngā wā ka mahi i raro i ngā kawenga taumaha, i ngā pāmahana teitei, i ngā āhuatanga pakaru rānei. Koinei te wāhi e whai wāhi ai te kaha ā-pūkaha o ngā mekameka maitai kore waikura. Ahakoa he ātete ki te waikura, he kaha tonu te kaha kume me te ātete ki te ngenge.

Nā tēnei he pai mō ngā mahi taumaha i ngā rāngai pēnei i te hinu me te hau, te keri maina, me te tukatuka kai—me mahi pai ngā mekameka i raro i te ahotea me te pānga tonu.

He iti te tiaki, he nui te pono

Ko tētahi o ngā painga o ngā mekameka kowiri tira e kore e arohia ko te iti o te tiaki. Nā te mea he ātete ki te waikura me te pakaru matū, he iti ake te hinu whakahinuhinu me te tirotiro e hiahiatia ana, ki te whakaritea ki ētahi atu rauemi mekameka.

I roto i ngā ahumahi he nui te waikura, ina mutu ngā mahi, ka ngaro te hua me te moni whiwhi, ko te whakaiti i te tiaki me te whakanui ake i te mahi te huarahi matua ki te whakahaere.

Te Utu me te Roa o te Ora: He Pūtea Whai Hua

Ahakoa he nui ake te utu tīmatanga o ngā mekameka kowiri tira i ngā mekameka maitai paerewa, ngā mekameka pania rānei, he nui ake te uara mō te wā roa. Nā te iti o te wā kore mahi, te iti ake o ngā whakakapinga, me te iti ake o ngā utu tiaki, ka tino iti ake te utu katoa o te mana whakahaere i roto i te wā.

Mō ngā kamupene e rapu ana i ngā otinga pakari, roa hoki i roto i ngā taiao waikura, ka tukuna e ngā mekameka maitai kore waikura he hokinga mai atamai, pumau hoki mō te haumitanga.

Ngā tono e hiahia ana kia pakari

Ka kitea noa e koe ngā mekameka kowiri tira i roto i:

Ngā taputapu tukatuka matū

Te kawe waka me te tuku kaipuke ki te moana

Te tukatuka kai me te inu

Ngā mahi rongoā me ngā mahi horoi rūma

Ngā pūnaha maimoatanga wai para me te waipara

I ia o ēnei āhuatanga, me mahi tonu te mekameka ahakoa te makuku, te tote, te waikawa, ngā kaihoroi ahumahi rānei—me te kore e whakararu i te haumaru, i te whai huatanga rānei.

Ko te mahi i roto i te taiao waikura nui e hiahia ana ki ngā otinga pakari e kore e pakaru i raro i te pēhanga. Ka whakaratohia e ngā mekameka maitai kore waikura te ātete ki te waikura, te kaha, me te pono e hiahiatia ana hei pupuri i te rere pai o ngā mahi - ahakoa i roto i ngā āhuatanga tino kino.

Kei te hiahia koe ki te whakapai ake i ō pūnaha mekameka kia roa ai te mau? Whakapā mai?Tukunga o Goodlucki tēnei rā, kia ako ai koe me pēhea e taea ai e ā mātou otinga maitai kore waikura te āwhina i a koe ki te pehi i te waikura me te whakapai ake i te mahi.
