Tirohia ngā wāhi tuatahi rānei, ko te kura, ka kite koe i ētahi atu mea e whai rēhita ana. Ko te rēhita kei roto i a matou wā katoa - mai i ngā kiritā kairama ki ngā pūwai ōhuti tino huarahi! Kei a koe i whakaaro tonu i te mea e ai ki te mea rēhita nei? Nō reira, ko ngā pūtake o te rēhita, e mōhiotia nei hei pūtake unuhia, he mea nui rawa kia mōhio ai tātou ki te mea e mohio ana tātou i te nuinga o te wā e hoko ana i ngā mea rēhita.
Ko te ahumiro i whakatauhia mai i ngā ingoa kai matua e rūnaki ana hei māta o te ahumiro. E pātupatutia ana hoki aua māta i runga i ngā wheako e tētahi, nō te petrolea, te raupapa me te taiepa. Nā te mea kaore ēnei mea i kitea noa, ka whai wāhi tonu ki te kawe atu i aua māta i runga i tō rātou whenua. Ko tēnei mahi ko te whakahauhau. Ka taea e koe te whakaaro i te whakahauhau he mea wehe i te taonga. I muri i te whakahauhau i ngā māta, me whakarerekē ki te wāhi e taea ai te whakamahinga hei hanga i ngā mea ahumiro.
He mātauranga e whai ake nei he whakawhiti i ngā hua o te whenua hei hanga i te pūoro. Ko tēnei mahi whakataki kāinga ka taka ki te whakaputu i ngā mokowāhi rahi hei iti. Ka mahia tēnei i te whakatakoto o te wera roa me te hopu nui ki runga i te kai, pērā i te mea ka tae ki te hāngī. Ka whakatetehia ngā mokowāhi rahi ki ngā wāhanga iti, e mihi ana hei monomera. Nō reira ngā monomera, ko ngā wāhanga iti e āwhina ana ki te hanga i ngā momo pūoro rerekē. Ka whakaaetia ngā monomera kia puta ai ngā polimera, pērā i te mea ka whakauruhia ngā tahuhu hanga hei hanga i ngā āhua rerekē.
Tēnā whakamātau tonu ki te tirohia ētahi atu o ngā momo raruraru e noho ana i roto i te pūoro. He paihere nui tētahi hua, ko te poliētine. Ka hangaia tēnei hua i tētahi monomera e mōhio ana hei ētine. Me te poliētine ka whakamahia i ngā mea e kitea ana e mātou i ngā rā o te ao, pērā i ngā kete pūoro i te pakihi me ngā wāhi kai moe. Kei a ia te pai me te manaaki, nā tana rangatiratanga me te manaaki.
He māteriale atu anō hei whakamahi ko te polypropylene. Ko tēnei i waihanga mai i tetahi monomer rānei, arā, te propylene. Kei te whakamahia te polypropylene ki te whai wānanga ārai kai, ngā pūtoto plastiketi, ā, hoki ki ētahi wāhanga o ngā motokā. He nui ngā rerekētanga o ngā mātae me ngā māteriale e taea ana te whai wānanga i te mīhini, i runga i te mea he aha te āhua o te hua tuatahi e hiahiatia nei. E ai ki ētahi, he mīhini nanei, he mīhini kē tonu, ā, ko tērā katoa ka tae ki ngā momo mātae e whakamahia.
Ki te hiahia ki tēnei hua, ko tētahi huarahi mō ngā kaiwhakawhiti kia whakamahia ngā māteriale e pūtere ana i te whenua. Ka pūtere ngā māteriale nei i te wā. Ko tēnei hei whakangungu i te taiao, e pā ana ki ētahi atu mīhini — kei reira tonu i ngā paheke whenua mō rau tau. Ki tēnā, ka taea e ētahi mīhini te whakapuare mai i ngā māngai tahutahu rānei, i te muka rākau rānei, kia pūtere, kia whakaora anō hoki te Papatūānuku.
He tūtohi nui atu hoki ngā rauemi whai wāhanga hei whakamahere mō te hanga rēhita taiao. He ara whakawhiti i te whakaputu, ka āhei tēnei ki te wānanga i ngā mea rēhita e pāngia ana e ngā tangata, kia whakatūria iho hei mea rēhita e taea ana te whakahoki i te wā. Ka whaimano hoki te whakaputu i te nui o ngā mea rēhita e takahi ana ki ngā wāhi whakaputu me ngā moana. Ko tēnā he nui rawa ki te tiaki i tō tātou whenua hei oranga noa iho mō te ao taiao.
