A phenomenon linked to the systematic lighting of towns, roads and villages, light pollution very significantly affects the biology of living species by modifying the natural alternation of day and night. The impacts of light pollution are multiple: sky observation, energy consumption, flora and fauna, human health. For more than ten years, the Pyrenees National Park has been committed to reducing light pollution. In particular, he became the co-sponsor of the Pic du Midi International Starry Sky Reserve alongside the Hautes-Pyrénées SDE and the Pic du Midi union. It has also defined a sensitivity threshold for certain nocturnal species beyond which light pollution has a strong impact on their activity, with the help of the Hautes-Pyrénées CPIE and the Conservatoire des Espaces Naturels.
Thus, in order to make as many people as possible aware of the beauty of the night and the issue of light pollution, the Pyrenees National Park is offering a series of free events on Saturday October 10, accessible to all.
