Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I te tau 1974 Frank Sherwood Rowland, Kaiwhakaako Matū i te Whare Wānanga o California i Irvine, me tana hoa whai muri i te taote a Mario J. Molina i kii ko nga konupora halogen rauropi roa-roa, penei i nga CFC, ka rite pea te ahua ki ta Crutzen i whakaaro ai mo te nitrous oxide. I kitea tata nei e James Lovelock, i a ia e rere ana i te Moana-nui-a-Kiwa ki te Tonga i te tau 1971, ko te nuinga o nga pūhui CFC i hangaia mai i te tau 1930 i kitea ai i te hau. I whakatau a Molina rāua ko Rowland, pēnei i te N2O, ka tae ngā CFC ki te papa o te rangi, ka whakakorehia e te hihi UV, e tuku ana i ngā ngota konupūmā. I te tau i mua ake, i whakaaturia e Richard Stolarski rāua ko Ralph Cicerone i te Whare Wānanga o Michigan he pai ake te Cl i te NO ki te whakaoho i te whakangaromanga o te hāora. He rite tonu te whakatau a Michael McElroy rāua ko Steven Wofsy i te Whare Wānanga o Harvard. Heoi anō, kāore tētahi rōpū i mōhio ko ngā CFC he pūtake nui pea o te chlorine stratospheric, engari, i tirotirohia e rātau ngā pānga pea o ngā tukunga HCl mai i te Space Shuttle, he tino iti ake.  Pātai: I hea a Rowland i te wā e whakaako ana?
