Durante millones de aos, las molculas de Ozono han salvaguardado la vida sobre nuestro planeta. Pero a partir del siglo pasado, el hombre ha puesto en peligro la capa de Ozono. Aunque las molculas de Ozono juegan un papel vital en la atmsfera, se trata de un compuesto relativamente poco abundante. Por cada milln de molculas de aire, menos de diez son de Ozono. El 90% del total de las molculas de Ozono de la atmsfera se agrupan en la estratosfera, capa situada entre los 10 y 40 Km sobre la superficie terrestre. El Ozono aqu situado absorbe parte de la radiacin ultravioleta proveniente del Sol y perjudicial para la vida en la superficie del planeta. Este Ozono es el amenazado por algunos contaminantes qumicos que hemos estado liberando en la atmsfera. Cerca de la superficie del planeta, el Ozono muestra su lado destructivo. Al reaccionar fuertemente con otro tipo de molculas puede daar los tejidos de plantas y animales. El Ozono en la troposfera, contribuye tambin a elevar la temperatura sobre al superficie de la Tierra en lo que se ha denominado Efecto Invernadero.
