IV. E tutuki ana te kapu aihikirīmi pepa i ngā paerewa taiao o Ūropi?
1. Ngā whakaritenga taiao mō ngā rauemi tākai kai i Ūropi
He tino kaha ngā whakaritenga taiao a te Kotahitanga o Ūropi mō te whakamahinga o ngā rauemi tākai kai. Ko ētahi o ēnei ko:
(1) Te haumaru o ngā rauemi. Me tutuki ngā rauemi takai kai i ngā paerewa akuaku me te haumaru e tika ana. Ā, kaua hoki e whai matū kino, e whai moroiti kino rānei.
(2) Ka taea te whakahou. Me hanga ngā rauemi tākai kai ki ngā rauemi ka taea te hangarua i te nuinga o te wā. (Pērā i ngā biopolymer ka taea te whakahou, ngā rauemi pepa ka taea te hangarua, me ētahi atu)
(3) He pai mō te taiao. Me tutuki ngā rauemi takai kai i ngā paerewa taiao e tika ana. Ā, kaua e waiho hei tūraru ki te taiao me te hauora o te tangata.
(4) Te whakahaere i ngā tukanga whakaputa. Me tino whakahaere te tukanga whakaputa o ngā rauemi takai kai. Ā, kaua e tukuna he tukunga o ngā poke e kino ai te taiao.
2. Te mahi taiao o ngā kapu aihikirīmi pepa ki te whakataurite ki ētahi atu rauemi
Ki te whakaritea ki ētahi atu rauemi takai kai e whakamahia whānuitia ana, he pai ake te mahi a ngā kapu aihikirīmi pepa mō te taiao. Ko ētahi o ēnei ko ngā mea e whai ake nei.
(1) Ka taea te hangarua i ngā rauemi. Ka taea te hangarua i te pepa me te kiriata paninga. Ā, me iti noa iho te pānga ki te taiao.
(2) He ngāwari te pirau o te rauemi. Ka tere, ka pirau noa hoki te pepa me te kiriata paninga. Mā tēnā ka māmā ake te whakahaere i ngā para.
(3) Te whakahaere i te taiao i te wā o te tukanga whakaputa. He pai te āhua o te tukanga whakaputa kapu aihikirīmi pepa ki te taiao. Ki te whakaritea ki ētahi atu rauemi, he iti ake ngā tukunga parahanga.
He rerekē, he nui ake ngā raruraru taiao o ētahi atu rauemi takai kai e whakamahia whānuitia ana. (Pērā i te kirihou, te kirihou pahuka.) He nui ngā para me ngā tukunga poke e puta mai ana i ngā hua kirihou i te wā o te tukanga whakaputa. Ā, kāore e ngawari te pirau. Ahakoa he māmā te kirihou pahuka, ā, he pai te mahi tiaki wera, ka puta mai i tana tukanga whakaputa te parahanga taiao me ngā raruraru para.
3. He tukunga parahanga kei te puta i te wā e hangaia ana ngā kapu aihikirīmi pepa?
Ahakoa he iti noa ngā para me ngā tukunga ka puta mai i ngā kapu aihikirīmi pepa i te wā o te tukanga whakaputa. Engari i te nuinga o te wā, kāore e nui te parahanga o te taiao. I te wā o te tukanga whakaputa, ko ngā mea matua e pāngia ana e ēnei ko:
(1) Pepa para. I te wā e hangaia ana he kapu aihikirīmi pepa, ka puta he nui o ngā pepa para. Engari ka taea te hangarua, te tukatuka rānei i ēnei pepa para.
(2) Te whakapaunga pūngao. Me whakamahi i tētahi nui o te pūngao (pēnei i te hiko me te wera) hei hanga kapu aihikirīmi pepa. Ka pā kino hoki ēnei ki te taiao.
Ka taea te whakatau i te rahinga me te pānga o ēnei poke i puta i te wā o te tukanga whakaputa mā te whakahaere whakaputa tika.
Te whakahaere me te whakatinana i ngā mahi tiaki taiao hei whakahaere me te whakaiti.
