Tom Uhlman Reihenfolge der Bücher (Chronologisch)

Una historia real sobre un científico contemporáneo que salvó la capa de ozono y el planeta, evitando un desastre en el medioambiente. Mario Molina es un científico mexicoamericano y un héroe de nuestros días que ayudó a resolver la crisis de la capa de ozono de la década de 1980. Se crió en la Ciudad de México y desde niño sintió curiosidad por los mundos ocultos que estudiaba a través de un microscopio. De joven, ya viviendo en California, descubrió que el clorofluorocarbono, o CFC, que se usa en millones de refrigeradores y aerosoles, estaba haciendo un agujero en la capa de ozono que protege la Tierra. Mario tuvo que alertar al mundo... ¡y rápido! Mario fue galardonado con el premio Nobel y con la Medalla Presidencial de la Libertad. Su inspiradora historia es una esperanza en la lucha contra el calentamiento global.
