Ozone Layer and Mario Molina's Contribution

The video discusses the ozone layer's role in protecting Earth from harmful radiation and the threat posed by chlorofluorocarbons (CFCs). It highlights Mario Molina's journey from Mexico to the U.S., where he and Sherry Roland discovered the damaging effects of CFCs in the 1970s. Despite resistance from chemical companies, Molina's advocacy led to a global agreement to ban CFCs. This action has set the ozone layer on a path to recovery.
