In areas where the night hours are not illuminated by artificial light, nocturnal animals can live out their normal way of life without environmental stress. Migratory birds remain undisturbed on their migration routes and are not distracted by artifi cial light. Insects, the natural pollinators for various plants, are protected because they are not attracted by unnatural light sources where they usually die. This in turn also allows animals \u2013 such as bats and hedgehogs \u2013 to hunt sufficient insects in their natural habitat.<\/p>\n\n\n\n<p>But day-active animals and humans also benefit from a dark night, as it supports the natural rhythm of life and a restful sleep. Last but not least, it is also a pleasure for us humans to observe the starry sky in really dark regions.<\/p>\n\n\n\n<div class=\"wp-block-uagb-image uagb-block-22018a62 wp-block-uagb-image--layout-default wp-block-uagb-image--effect-static wp-block-uagb-image--align-none\"><figure class=\"wp-block-uagb-image__figure\"><img decoding=\"async\" srcset=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/02\/grafik-14-1024x470.png ,https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/02\/grafik-14.png 780w, https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/02\/grafik-14.png 360w\" sizes=\"auto, (max-width: 480px) 150px\" src=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/02\/grafik-14-1024x470.png\" alt=\"\" class=\"uag-image-103\" width=\"1024\" height=\"326\" title=\"grafik\" loading=\"lazy\" role=\"img\"\/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p><strong>Heavy light pollution\r\n\r\n<\/strong>dazzling, wasteful, with high blue content<strong>\r\n\r\n\r\n<\/strong><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-align-center has-large-font-size\"><strong>&gt;&gt;&gt;&gt;&gt;&gt;&gt;<\/strong><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<p><strong>Low light pollution<\/strong><br><br>focused, efficient, with low blue content, additionally dimmed or switched off at certain times<\/p>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-audio\"><audio controls src=\"https:\/\/lehrpfad.umwelt-campus.de\/wp-content\/uploads\/2025\/09\/113_2_eng.mp3\"><\/audio><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"margin-top:0;margin-bottom:0\">Criteria for the sustainable use of light outdoors<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Illuminate only those areas that are absolutely functionally necessary.<\/li>\n\n\n\n<li>Avoid light smog: illuminate the object precisely (with a narrow cone of light), without glare and with downward beams.<\/li>\n\n\n\n<li>Keep the light color below 3,000 Kelvin, because warm light tones have a lower attracting effect on insects<\/li>\n\n\n\n<li>Avoid illuminating bodies of water and green areas.<\/li>\n\n\n\n<li>Avoid decorative lighting of buildings, monuments and others structures or at least dim the light and switch it off in the late hours of the night.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" style=\"margin-top:0;margin-bottom:0\">Sensitively shining on historic buildings<\/h3>\n\n\n\n<p>Light also has a highly aesthetic component.
