Mario and the hole in the sky How a chemist saved our planet

Gr 1--4--Growing up in Mexico, Mario Molina loved exploring the world around him and performing experiments with his microscope. After attending boarding school in Switzerland and receiving his PhD, Molina began work in the United States, where he made a horrific discovery: CFCs, chemicals used in countless everyday items, were damaging the environment by destroying the ozone layer. Despite Molina and his colleague F. Sherwood Rowland's attempts to publicize this discovery, they were not taken seriously until scientists discovered a huge hole in the ozone above Antarctica. Finally, Molina and Rowland's hard work led to almost every country agreeing to stop the production of CFCs. Vibrant, imaginative illustrations convey the possibilities of science and the urgency of Molina's discoveries and depict Molina's interest from an early age. Both English and Spanish texts flow smoothly. VERDICT An excellent addition to children's nonfiction collections, and sure to be a great highlight of Hispanic Heritage Month biography collections.--Selenia Paz, Harris County Public Library, Houston

"The sky is falling, the sky is falling"but unlike the supporting cast of "Chicken Little," no one pays attention to Mexican-born chemist Dr. Mario Molina's call to action.Rusch's compelling narrative captures the dread and frustration felt by Molina and fellow University of California-Irvine chemist Sherwood Rowland as they race to head off the depletion of the ozone layer. Excessive amounts of chlorofluorocarbons are being released into the atmosphere from air conditioners, refrigerators, spray cans, etc. at an alarming rate. Their initial, unsuccessful efforts to convince the media and Congress about the serious chemical threat to everyone on this planet parallels Nobel Prize winner Molina's current struggle to address our current crisis of global warming. Martinez's Disney-esque illustrations, set against dark or murky-colored backgrounds, detract only slightly from the strong storyline. A succinct epilogue summarizes Molina's many accomplishments, and a chart comparing the similarities between ozone depletion and global warming is appended. Additionally, a suggested reading list and corresponding links are provided. Unfortunately, the timeline is printed across the endpaperslimiting access to the information once the protective jackets are affixed to school or library copies. A Spanish-language edition will be simultaneously released, with a translation by Carlos E. Calvo.A timely and fascinating look at what courage and focused, informed action can accomplish.

Mario Molina was born in Mexico City on March 19, 1943. By the time he was six, the world was awash in amazing new products made from amazing new chemicals. Spray. Spray.  Mario's mother misted perfume onto her wrist.  Squirt. Squirt.  Someone polished a window.  Spurt. Spurt.  A press of a button propelled cleaner onto a counter, paint onto a fence, and hair spray onto curls. But one of the new chemicals, used in millions of spray cans and refrigerators, had a dangerous side that no one had yet discovered. . . . "¡Feliz cumpleaños, Mario!" On Mario's eighth birthday his parents gave him a microscope.  Mario peered through the lens at a drop of water.   Boring,  he thought. Then he began to wonder:  What would happen if I looked at dirty water? Mario soaked some lettuce and let it rot. After a few days the gooey, brownish-green mess smelled awful. Mario plugged his nose, sucked up a dropper of the filthy water, and dripped it onto a slide. He peered into the lens and gasped. "¡Increíble!  All these amazing creatures in just one drop of water!" Mario studied everything he could under the microscope: sparkling salt crystals, tomatoes, onions, chilies from salsa--even toothpaste. Mario was itching to see more. "Can I use this bathroom as a laboratory?" he asked his parents. "No one ever uses it." " ¡Dios mío!  " his mother groaned. "Sounds messy."   But they removed the toilet for him and installed some shelves.    "Don't blow anything up," his father warned.
