Mario Molina was a Mexican chemist who was awarded the Nobel Prize in Chemistry in 1995 for his work on atmospheric chemistry and the discovery of the threat posed by chlorofluorocarbons (CFCs) to the Earth's ozone layer. Molina's research showed that CFCs released into the atmosphere through human activity were depleting the ozone layer, which protects the Earth from harmful ultraviolet radiation.
Molina's discovery was a major breakthrough in environmental science and led to the creation of the Montreal Protocol, an international agreement signed in 1987 to phase out the use of CFCs and other ozone-depleting substances.
In addition to his work on the ozone layer, Molina was also a leading voice on climate change and the need for sustainable energy solutions. He was a professor at the University of California, San Diego, and a member of the National Academy of Sciences, the Pontifical Academy of Sciences, and the United States President's Committee of Advisors on Science and Technology.
Molina's achievements serve as a reminder of the importance of scientific research and the role of scientists in addressing global challenges. His work on the ozone layer has had a significant impact on environmental policy and helped to protect the Earth for future generations.
