Mario Molina

Mario Molina was a Mexican chemist known for his groundbreaking research on the depletion of the ozone layer caused by chlorofluorocarbons (CFCs). His work in the 1970s demonstrated how these man-made chemicals released into the atmosphere were harmful to the ozone, which protects the Earth from harmful ultraviolet radiation. Molina's findings led to global awareness and the adoption of the Montreal Protocol in 1987, an international treaty to phase out CFCs. He received the Nobel Prize in Chemistry in 1995 for his contributions to environmental science, playing a crucial role in efforts to preserve the Earth's atmosphere.
