He hangarau pūoko atamai hei āwhina i ngā kaimahi pāmu ki te whakamahi i ngā tongi me te whakaiti i ngā kino ki te taiao.
Mā te hangarau, e whakaahuatia ana i roto i te maheni Natural Foods, ka taea e ngā kaihanga te whakatau i te wā pai hei whakamahi i te tongi ki ngā hua me te nui o te tongi e hiahiatia ana, me te whai whakaaro ki ngā āhuatanga pēnei i te rangi me ngā āhuatanga o te oneone. Mā tēnei ka whakaitihia te tongi nui rawa o te oneone, he utu nui, he kino hoki ki te taiao, ka tukuna te hau kati kōtuhi o te hauota waikura, ka poke hoki i te oneone me ngā awa.
I ēnei rā, nā te nui rawa o te whakamomona kua kore e taea te whakamahi i te 12% o ngā whenua ahuwhenua o te ao, ā, kua piki ake te whakamahinga o ngā maniua hauota mā te 600% i roto i ngā tau 50 kua hipa.
Heoi, he uaua ki ngā kaihanga hua te whakahaere tika i tā rātou whakamahinga tongi: ki te nui rawa, ka tūpono ka kino te taiao, ki te iti rawa te whakapaunga, ka tūpono ka iti ake ngā hua;
E ai ki ngā kairangahau o te hangarau pūoko hou, ka whai hua pea tēnei ki te taiao me ngā kaihanga.
Ko te pūoko, e kiia nei ko te pūoko hau hiko mahi-matū pepa (chemPEGS), ka ine i te nui o te ammonia i roto i te oneone, he matū ka hurihia hei nitrite me te nitrate e ngā huakita oneone. Ka whakamahia e ia tētahi momo matauranga horihori e kiia nei ko te ako mīhini, ka whakakotahi i tēnei me ngā raraunga mō te rangi, te wā mai i te whakamahinga tongi, ngā inenga o te pH oneone me te kawe hiko. Ka whakamahia e ia ēnei raraunga hei matapae i te nui o te hauota o te oneone i nāianei me te nui o te hauota 12 ngā rā kei te heke mai hei matapae i te wā pai ki te whakamahi tongi.
E whakaatu ana te rangahau me pēhea e taea ai e tēnei otinga hou, iti te utu, te āwhina i ngā kaihanga ki te whiwhi i te painga nui mai i te iti rawa o te tongi, inā koa mō ngā hua e nui ana te tongi pērā i te witi. I te wā kotahi, ka taea e tēnei hangarau te whakaiti i ngā utu a ngā kaihanga me te kino ki te taiao mai i ngā tongi hauota, te momo tongi e whakamahia whānuitia ana.
I mea atu a Tākuta Max Greer, te kairangahau matua, nō te Tari Hangarau Koiora i Imperial College London: "Kāore e taea te whakanui rawa i te raruraru o te nui rawa o te whakamomona, mai i te tirohanga taiao me te tirohanga ōhanga. Kei te heke te hua me te moni whiwhi e pā ana i tēnei tau, ā, kāore i ngā kaihanga ngā taputapu e hiahiatia ana hei whakatika i tēnei take."
"Ka taea e tā mātou hangarau te āwhina i ngā kaiwhakatipu ki te mārama ki ngā taumata haukini me te pākawa waro o nāianei i roto i te oneone, me te matapae i ngā taumata ā muri ake nei i runga i ngā āhuatanga o te rangi. Mā tēnei ka taea e rātou te whakatikatika i tā rātou tono tongi kia rite ki ngā hiahia motuhake o tā rātou oneone me ā rātou hua."
Ka tukuna e te tongi hauota nui rawa te hauota waikura ki te rangi, he hau kati kōtuhi e 300 ngā wā he kaha ake i te hauhā waro, ā, ka whai wāhi atu ki te raruraru āhuarangi. Ka taea hoki te horoi atu i te tongi nui rawa e te wai ua ki roto i ngā awa, ka tangohia te hāora o ngā mea ora i roto i te wai, ka puāwai te rimurimu, ka whakaiti i te kanorau koiora.
Heoi anō, he uaua tonu te whakarerekē tika i ngā taumata tongi kia rite ki ngā hiahia o te oneone me ngā hua. He onge te whakamātautau, ā, ko ngā tikanga o nāianei mō te ine i te hauota oneone ko te tuku tauira oneone ki te taiwhanga—he tukanga roa, he utu nui hoki, ā, kāore e whai hua ngā hua i te wā e tae atu ai ki ngā kaiwhakatipu.
I mea atu a Tākuta Firat Guder, he kaituhi matua, he kairangahau matua hoki i te Tari Hangarau Koiora o Imperial: "Ko te nuinga o ā tātou kai i ahu mai i te oneone – he rauemi kore e taea te whakahou, ā, ki te kore tātou e tiaki ka ngaro. Anō, me te parahanga hauota mai i te ahuwhenua ka puta he raruraru mō te ao e tumanako ana mātou ki te āwhina ki te whakaoti mā te ahuwhenua tika, e tumanako ana mātou ka āwhina i te whakaiti i te nui rawa o te tongi me te whakanui ake i ngā hua hua me ngā hua o te hunga whakatipu."
