Ko te National Institutes of Health i Maryland, i te United States o Amerika, kua whakaputa i ngā rangahau hou e whakaatu ana
kāore ngā taumata CO₂ teitei e whakatairanga anake i te tipu o ngā otaota, engari ka piki hoki te
kōwae o ngā matū whai tikanga rongoā i roto i a rātou.
He tino whai pūhui kaha ngā otaota rongoā kua whakamahia i roto i te rongoā taiao mō ngā mano tau.
Nā te mea i tino nui ake te nui o te CO₂ i te rangi i ngā mano tau ki muri i ēnei rā, he tino pea
i kaha ake ngā otaota rongoā i taua wā i ēnei rā.
Ko te mutunga iho, e kitea ana he nui ake ngā painga o te pikinga o ngā taumata hau waikura i te āhuarangi i ngā kino.
Ka ara ake te pātai: i te wā e huna ana, e whawhai ana rānei ngā kaiwhakatūpato āhuarangi i roto i te tōrangapū me ngā pāpāho
matua i ngā painga o te CO₂, pērā i ēnei, kāore rānei tēnei e whakaatu ana i a rātou me ō rātou rangatira
huna kei muri i te Mahere 2030 a te UN hei hunga kino, he hunga whakaparahako i te tangata?
