Title
La contaminación lumínica
Sinopsis
El cielo oscuro no solo constituye un importante patrimonio científico y cultural, sino también un eje en torno al que desarrollar actividades de turismo sostenible y cuya carencia, derivada de la contaminación lumínica, afecta a nuestra salud y a la de los ecosistemas. El estudio del firmamento ha ido de la mano del desarrollo de las diferentes civilizaciones y ha sido y es una importante fuente de conocimiento. Su observación fue determinante para el desarrollo de la navegación por mar o para precisar el inicio de la época de siembra en las sociedades agrícolas; nos ha permitido también conocer la posición de nuestro planeta en la galaxia o descubrir que compartimos composición química con las estrellas. Esta obra profundiza en el conocimiento de un problema ambiental creciente: la contaminación lumínica, de la que analiza sus principales causas. A través de sus páginas aprenderemos a identificar cuándo un cielo está contaminado y qué técnicas e instrumentos se utilizan para medir dicha contaminación. Además, presenta los resultados de las últimas investigaciones científicas relacionadas con los impactos de la contaminación lumínica y plantea posibles acciones para mitigar este problema creciente.
