How much light is too much light? Satellite pictures show our planet as a brightly glowing orb, and in our era of constant illumination, light pollution has become a major issue. The world’s flora and fauna have evolved to operate in the natural cycle of day and night. But in the last 150 years, we have extended our day—and in doing so have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things, including ourselves.

The world's flora and fauna have evolved to operate in the natural cycle of day and night. But constant illumination has made light pollution a major issue. From space, our planet glows brightly, 24/7. By extending our day, we have forced out the inhabitants of the night and disrupted the circadian rhythms necessary to sustain all living things. Our cities' streetlamps and neon signs are altering entire ecosystems. As a devoted friend of the night, Johan Eklöf encourages us to appreciate natural darkness, its creatures and its unique benefits.

Natur- und Artenschutz sind in aller Munde, aber ein Aspekt, der unsere Natur massiv bedroht, wird dabei meist außer Acht gelassen: Die Lichtverschmutzung – das künstliche Licht, das unsere Städte und Dörfer erhellt. Alle Rhythmen der Natur sind letztlich abhängig vom Wechsel zwischen Tag und Nacht. Fällt dieser Wechsel weg, weil die Nacht verschwindet, dann hat das gravierende Folgen. Vögel singen in allzu heller Umgebung mitten in der Nacht.
