Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 1974 Frank Sherwood Rowland, Purofesa weChemistry paYunivhesiti yeCalifornia paIrvine, uye mushandi wake wepashure pechiremba Mario J. Molina akataura kuti makemikari ane upenyu hurefu ane halogen, akadai seCFCs, angaita nenzira yakafanana neizvo Crutzen akanga ataura nokuda kwe nitrous oxide. James Lovelock akanga achangobva kuwana, mukati mokubvakacha muSouth Atlantic muna 1971, kuti inodokuva yose yemakemikari eCFC akagadzirwa chifo chokugadzirwa kwawo muna 1930 yakanga ichiripo mumhepo yakapoteredza pasi. Molina naRowland vakagumisa kuti, kufanana neN2O, maCFC aizosvika mu stratosphere umo aizoparadzaniswa neUV chiedza, achibudisa maatomu eklorini. Gore rakanga rapfuura, Richard Stolarski naRalph Cicerone paUniversity of Michigan vakanga varatidza kuti Cl inonyatsobudirira kupfuura NO pakuita kuti ozone iparadzwe. Mhedziso dzakafanana dzakasvikwa naMichael McElroy naSteven Wofsy paHarvard University. Boka racho, zvisinei, rakanga risina kuziva kuti maCFC akanga ari manyuko makuru anobvira eklorini ye stratosphere - panzvimbo pezvo, vakanga vave vachiongorora migumisiro inobvira yezvinyorwa zveHCl zvinobva muSpace Shuttle, izvo zviduku zvikuru.  Mubvunzo: Rowland akanga ari purofesa kupi?
