Mario Molinachemist, Nobel laureate
Born: March 19, 1943
Birthplace: Mexico City
At the University of California at Berkeley in 1973, Molina and Sherwood Rowland began researching chlorofluorocarbons (CFCs), then widely used in refrigerators, spray cans, and cleaning solvents. They discovered that the release of CFCs could destroy the ozone layer in the stratosphere, allowing more ultraviolet light to get through to Earth and potentially increasing the rate of skin cancer. Their efforts led to CFC production being banned in most countries, and they received the 1995 Nobel Prize in Chemistry.
