The true story of a Mario Molina, a Mexican-American scientist and modern-day hero who helped solve the ozone layer crisis of the 1980s
Mario grew up in Mexico City and as a child was curious about the hidden worlds he studied through a microscope. As a young man living in California, he discovered that chlorofluorocarbons, or CFCs, which are used in millions of refrigerators and aerosol cans, were eating a hole in the ozone layer that protects the Earth. Mario had to alert the world...and fast!
Mario was awarded the Nobel Prize and the Presidential Medal of Freedom. His inspiring story is a hope in the fight against global warming.
