Pānga Taiao o te Kirihou
He rauemi tino whai hua te kirihou i roto i te oranga o ia rā, engari he pānga kino anō hoki ki te taiao. Nā te mea kāore e pirau ngāwari te kirihou, he maha ngā wā ka poke ngā moana, ka pā kino hoki ki ngā rauropi moana. E ai ki ngā rangahau taiao, tata ki te 8 miriona tana o te kirihou e uru ana ki ngā moana i ia tau.
Ngā Mahi Whakahaere:
– Te hangarua: Whakanuia ake ngā mahi hangarua hei whakaiti i ngā para kirihou. He maha ngā wā ka hangaruahia ngā kirihou pēnei i te PET me te HDPE hei hanga hua hou.
– Te Whakaiti i te Whakamahinga: Whakaitihia te whakamahinga o ngā kirihou kotahi te whakamahinga, ka huri ki ngā rauemi e pai ake ana ki te taiao pērā i te pepa, te konganuku, te karāhe rānei.
– Auahatanga Rauemi: Kei te haere tonu ngā rangahau hei kimi i ngā kirihou rerekē ka pirau, me te whakanui ake i te whai huatanga o te tukanga hangarua.
Whakamutunga
He nui ngā takoha a te kirihou ki te whanaketanga hangarau me te oranga o te tangata. He rerekē ngā whakamahinga me ngā painga o ngā momo kirihou, ā, he māmā ake te oranga o ia rā. Heoi, nā te whānui haere o te whakamahinga o te kirihou, me mōhio anō hoki tātou ki ōna pānga ki te taiao. Mā te mahi hangarua, te whakaiti i te whakamahinga, me te rangahau i ngā huarahi kē atu e pai ake ana ki te taiao, ka taea tonu e tātou te whai hua i ngā painga o te kirihou me te kore e kino ki tō tātou ao.
