Dr. Mario Molina, a Mexican chemist who efficiently satisfied governments to work collectively to avoid wasting the planet’s ozone layer has been honored by Google Doodle. Molina died of a coronary heart assault on the age of 77 in 2020.
Dr. Molina, a co-recipient of the Nobel Prize in Chemistry in 1995, was one of many researchers who found how chemical compounds deplete the Earth’s ozone defend, which is essential for safeguarding people, vegetation, and wildlife from dangerous ultraviolet mild.
For years, chemical compounds in hair spray and fridges wreaked havoc on the ozone layer, the protecting shroud that protects us from the solar’s dangerous ultraviolet radiation. Nonetheless, it wasn’t till 1974 that individuals started to take discover.
In that yr, Mexican scientist Mario Molina printed a research demonstrating that chlorofluorocarbons, that are broadly utilized in fridge coolants, spray paint, deodorant sprays, and different aerosol merchandise, had been depleting the ozone layer. The implications had been dire, as a result of with out the ozone layer to defend us from the solar, our planet can be uninhabitable. His work influenced world environmental coverage.
Google devoted its Doodle to Molina on the Nobel Prize-winning scientist’s eightieth birthday to honour his pioneering efforts to fight an environmental catastrophe.

Dr. Mario Molina, who was born in Mexico Metropolis on March 19, 1943, was drawn to science at a younger age, changing a rest room in his dwelling right into a makeshift laboratory for his chemistry units.
“I used to be already fascinated by science earlier than getting into highschool,” Dr. Mario Molina wrote in his Nobel biography. “I recall how excited I used to be after I first checked out paramecia and amoebae by way of a slightly primitive toy microscope.”
Molina returned to Mexico after being despatched to a Swiss boarding college on the age of 11 to review chemical engineering on the Nationwide Autonomous College of Mexico earlier than incomes a doctorate in bodily chemistry from the College of California, Berkeley, in 1972.

Molina found that CFCs within the higher environment could possibly be damaged down by ultraviolet radiation, releasing chlorine atoms that destroyed ozone molecules a yr later whereas working with F. Sherwood Rowland of the College of California at Irvine.
In 1974, their findings had been printed within the journal Nature.
Their findings had been criticized by industries that depend on CFCs, with one government claiming that the pair’s concept was “orchestrated by the Ministry of Disinformation of the KGB.” Nonetheless, British scientists found a large gap within the ozone layer over Antarctica in 1985.
This discovery prompted governments everywhere in the world to signal the Montreal Protocol within the Nineteen Eighties to part out the usage of ozone-depleting substances. The settlement was dubbed “essentially the most profitable worldwide effort to fight local weather change and environmental degradation” by Science journal.
Molina and Rowland shared the Nobel Prize in Chemistry in 1995 with Paul J. Crutzen of the Max Planck Institute in Germany. The Royal Swedish Academy of Sciences mentioned in asserting the award that the researchers “have contributed to our salvation from a worldwide environmental downside that would have catastrophic penalties.”
