Mario and the Hole in the Sky
How a Chemist Saved Our Planet
Illustrated by Teresa Martinez
How did a boy from Mexico City become a Nobel Prize-winning chemist who saved our planet?
Eight-year-old Mario wanted to learn all he could about chemistry. He examined everything under a microscope—from rotten lettuce to toothpaste.
As an adult, Mario continued studying chemistry—and discovered something scary. CFCs, used in millions of refrigerators and spray cans, were destroying the earth’s
protective ozone layer. Without ozone, deadly solar radiation would bombard our planet. Mario had to warn the world—and quickly.
This is the true story of Mario Molina, the Mexican-American chemist who brought the world back from the brink of environmental catastrophe. His inspiring story offers hope in the face of today’s battle against global warming.
