Google's logo is redesigned so as to include O3, the chemical formula of Ozone. The doodle dedicated to Mario Molina shows him pondering next to an artistic rendition of a depleted Ozone cover. Molina's research was the foundation of the landmark Montreal Protocol, which banned the making of nearly 100 harmful chemicals. The Google Doodle on March 19 marked the birthday of Mario Molina, the Nobel Prize-winning Mexican chemist who alerted the world to the dangers of Ozone layer depletion.
