Mario Molina was a Mexican chemist who was born on March 19, 1943, in Mexico City, Mexico. He is famous for his research on the effects of chlorofluorocarbons (CFCs) on the ozone layer, which led to the discovery of the Antarctic ozone hole. He was the co-recipient of the 1995 Nobel Prize in Chemistry for his work in atmospheric chemistry.

Molina studied chemical engineering at the National Autonomous University of Mexico and later received his Ph.D. in physical chemistry from the University of California, Berkeley. In 1974, he became interested in the effects of CFCs on the ozone layer, and in 1975 he published a paper in the journal Nature describing the potential danger of CFCs to the environment. His research contributed to the signing of the Montreal Protocol in 1987, an international agreement to phase out the production of CFCs.

Google placed a doodle on his 80th birthday on March 19, 2023, to commemorate his contributions to science and his dedication to protecting the environment.

Here are ten interesting facts about Mario Molina:

1. Molina was the first Mexican-born scientist to receive the Nobel Prize in Chemistry.
2. He was also the first Hispanic scientist to receive the National Medal of Science in the United States.
3. Molina co-founded the Mario Molina Center for Strategic Studies on Energy and the Environment, a non-profit organization dedicated to promoting sustainable development.
4. In addition to his work on the ozone layer, Molina also researched the effects of air pollution on human health.
5. He was a member of the United Nations Secretary-General's Scientific Advisory Board.
6. Molina served as a professor of chemistry and biochemistry at the University of California, San Diego, and later at the University of California, Berkeley.
7. He was a member of the Pontifical Academy of Sciences, the National Academy of Sciences, and the American Academy of Arts and Sciences.
8. Molina was awarded the Presidential Medal of Freedom by President Barack Obama in 2013.
9. He was a strong advocate for science education and worked to promote STEM education in underprivileged communities.
10. Molina passed away on October 7, 2020, at the age of 77.

Mario Molina was a renowned chemist who dedicated his life to studying the effects of human activities on the environment. He was born on March 19, 1943, in Mexico City, Mexico, and passed away on October 7, 2020, at the age of 77. He received his undergraduate degree in chemical engineering from the National Autonomous University of Mexico, and later obtained his Ph.D. in physical chemistry from the University of California, Berkeley.

Molina's research on the effects of chlorofluorocarbons (CFCs) on the ozone layer is what he is most famous for. In the 1970s, he became interested in the effects of CFCs, which were widely used in refrigerants and aerosol sprays at the time. He conducted a series of experiments that showed that CFCs could be broken down by sunlight in the upper atmosphere, releasing chlorine atoms that could destroy ozone molecules. Molina published his findings in a 1974 paper in the journal Nature, which caught the attention of the scientific community and policymakers.

Molina's research was significant because it led to the discovery of the Antarctic ozone hole, a large area of depleted ozone over Antarctica that is caused by the release of CFCs into the atmosphere. The discovery of the ozone hole raised alarm bells around the world and led to the signing of the Montreal Protocol in 1987, an international agreement to phase out the production of CFCs. Molina played a key role in the negotiations that led to the signing of the protocol, and his work on the ozone layer earned him the 1995 Nobel Prize in Chemistry, which he shared with two other scientists.

In addition to his work on the ozone layer, Molina also conducted research on air pollution and its effects on human health. He was particularly interested in the effects of air pollution on children and pregnant women, and he conducted several studies that showed the link between air pollution and respiratory diseases, such as asthma. He was also involved in the development of the California Clean Air Act, which has been credited with improving air quality in California.

Molina was a strong advocate for science education and worked tirelessly to promote STEM education in underprivileged communities. He believed that everyone should have access to quality education and that scientific research should be accessible to all. He was a member of several scientific organizations, including the National Academy of Sciences, the American Academy of Arts and Sciences, and the Pontifical Academy of Sciences.

Throughout his career, Molina received numerous awards and honors for his contributions to science and the environment. He was awarded the National Medal of Science in the United States, the Tyler Prize for Environmental Achievement, the Volvo Environment Prize, and the Blue Planet Prize, among others. In 2013, he was awarded the Presidential Medal of Freedom, the highest civilian honor in the United States, by President Barack Obama.

In addition to his scientific work, Molina was also an advocate for social justice and human rights. He spoke out against discrimination and inequality and was a champion of diversity and inclusion. He believed that science should be used to make the world a better place for all people, and he worked to make that vision a reality throughout his life.

In conclusion, Mario Molina was a brilliant scientist and a tireless advocate for the environment, education, and social justice. His work on the effects of CFCs on the ozone layer and his advocacy for environmental protection have had a profound impact on the world, and his legacy will continue to inspire future generations of scientists and activists.
