Mario Molina was a renowned atmospheric chemist who, along with Frank Sherwood Rowland, discovered the role of chlorofluorocarbons (CFCs) in the depletion of the ozone layer. Their groundbreaking research in the 1970s demonstrated how CFCs, commonly used in refrigeration and aerosol propellants, break down ozone molecules in the stratosphere. This work significantly contributed to the global awareness and policy changes regarding ozone protection, leading to the Montreal Protocol in 1987, which aimed to phase out the production of ozone-depleting substances. Molina's efforts earned him the Nobel Prize in Chemistry in 1995.
