The true story of how a scientist saved the planet from environmental disaster.
Mexican American Mario Molina is a modern-day hero who helped solve the ozone crisis of the 1980s. Growing up in Mexico City, Mario was a curious boy who studied hidden worlds through a microscope. As a young man in California, he discovered that CFCs, used in millions of refrigerators and spray cans, were tearing a hole in the earth's protective ozone layer. Mario knew the world had to be warned--and quickly. Today Mario is a Nobel laureate and a recipient of the Presidential Medal of Freedom. His inspiring story gives hope in the fight against global warming.
This is the story of Mario Molina, a Mexican chemist who was responsible, with his colleagues F. Sherwood Rowland and Paul J. Crutzen, for the discovery of the hole in the ozone layer above Antarctica. Readers learn how Mario’s parents converted an old bathroom into a laboratory for their son and how his aunt, Esther Molina, also a chemist, helped and challenged him. The story follows Mario’s trajectory as he continues his medical studies abroad and ends up in California studying the chlorofluorocarbons that had been amassing and damaging the atmosphere. Engaging illustrations and information presented in an easy-to-read format make this title an excellent addition to any Spanish-language nonfiction collection. An epilogue, compare-contrast chart, bibliography, time line, and an author’s note are included.
