Ko te ao he wā e whakarerekē ana ake tonu, ā, he nui ngā tangata kē kērangi kia kitea ai tō tātou whenua i te oranga. Whakamahi low density polyethylene he tino pai tēnei kia whai wā. Nō te mīhini iti, he para hau e rere ana me te torotoro nui ake i ētahi atu momo para. Ko tēnei āhuatanga pūmau e mahi anō hoki i a rātou ki te whakaorangorangoa. Ki te whakamahia te para mīhini iti nei, ka mahi tātou i tō tātou wā moe ki te itinga o ngā mea kua korekore ki ngā wāhi takutaku. Ko tēnei ko te mea nui rawa, nā te mea ko te iti noa iho o ngā mea kore iwi ka hoki mai he ao katoa nui tonu. Ahakoa, ko te huringa kai hoko hei hanga i ngā mea hou para mai i te para mīhini iti he iti noa iho. Ko tēnei he whakaritea mō te tiaki i ngā taonga o tō tātou whenua me te whakanuia i tō tātou wā katoa.
Ko te polyethylene pūtauheke kaua he tino moutapu ldpe low density polyethylene . Ko tēnei rākau kaihua e whakamahi ana ngā toa maha, ēngari nō te wāhi matihiko i te waehanga. He mea mohio nui tēnei, ka taea te whakatū ki ngā āhua maha, koia nei he pai ake hei rauemi whakapakoko. Ko tēnei ka taea e ia te whakarite i ngā mea o ngā roa me ngā āhua katoa, mai i ngā kai kotahi ki ngā pūtē maha. Nō reira, ka taea e te polietilini iti i te huringa. Ko tēnei he whakariterite, nā te tīmata huringa ka taea te whakaora i te taiao. Ko te huringa ka taea e tātou te hanga i ngā mea hou mai i te kaihua whakamahunga, e kore e tangohia.
Pēnei i ngā mea katoa, he pai āhe tonu te pūnamu iti i te whakamahere, engari he nui ētahi wāhi. Me pēhea rawa, ko te waehanga tino hira ki te whakaorangia. Ko tēnei ka whakaiti i ngā huanga me ngā rauemi mō te hanga i ngā mea hou mai i te pūnamu whakahokia. He mea hē ki te roa, ko te pūnamu iti nei kei te manaaki i te wae o te rangi, me te whakaputu hei whakaae i te haere. Kāore i konei, he nuinga hoki o ngā hapa. Kaore te pūnamu iti i te mana motuhake i runga i ētahi atu momo pūnamu. Nā tēnei, kaore ia i te whakanui ki te whakamahere mō ia mea, inā e hiahiatia ana te kaha nui.
Te polipropihi o te mohiotanga iti he momo atu anō hoki o te mohiotanga iti. Ka whakamahi ngātahi nui i tēnei mohiotanga mo ētahi atu whakamahinga. Hei tauira, ka whakamahi ia ki te pākete kai (nō reira e tika ana, nā tērā e taea ana te tiaki i te kai). Ko tēnei ka whai mana ki te whakamahia hei tiaki i ō rātou kai me ō rātou nonoti, kāore i te whakarite i ngā rūma kīmika e hanga ai ngā uiui. Ko te polipropihi o te mohiotanga iti ka whai mana hoki ki ngā rautaki hauora, nā tērā ka taea te whakapakari me te mana ki te hauora. Ko tēnei he nui rawa te noho i roto i ngā wāhi hauora pērā i ngā hapori whakauru hoki me ngā rōpū hinengaro, nō reira ko te whakapakari he mea nui.
Ko te Yuezheng he kāwanatanga matua. Nō reira, mēnā e mōhio ana tātou i te hēra o te roroa iti whakarongo i tō mahi. Ko te roroa iti e whakaiti ana i te waihotanga, ā, e āwhina ana i te taiao hoki. E hiahiatia ana e tātou ngā mahi hei whakapakari i te hauora o te whenua. Ka whakangahau te roroa iti i ā mātou mahi hei whai mana, hei whai kareenga. Kāore i te pai noa iho tēnei mō te whenua, ka whakaorangia anō e ngā tūroro o tātou i te wā e hīkaro nei, nā te mea ko te mahi iti e hiahiatia ai ngā utu haere me ngā utu whakahaere.
