Illuminating the Night: Taming Light Pollution for a Better World

As the sun sets and the world transitions into darkness, artificial light takes centre stage. We illuminate our streets, buildings, and landscapes, often without considering the consequences. But what if I told you that our well-intentioned lighting choices can harm both people and the natural world? Let’s explore the growing importance of limiting obtrusive light and its impact on our lives, flora, fauna, and the night sky.

The Dark Side of Light, What Is Obtrusive Light?

Obtrusive light, also known as light pollution, occurs when artificial illumination spills beyond its intended area. Think of that overly bright streetlamp glaring into your bedroom window or the neon glow drowning out the stars. It disrupts our natural rhythms, affects wildlife behaviour, and erodes our connection to the cosmos.

Excessive artificial light disrupts our sleep patterns, messes with our circadian rhythms, and contributes to health issues like insomnia and anxiety. Imagine a world where our cities and towns embrace softer, more thoughtful lighting—where we can rest, rejuvenate, and reconnect with the night.

Birds, insects, and nocturnal creatures rely on darkness for survival. Obtrusive light confuses their navigation, disrupts mating rituals, and alters feeding habits. Bats, those elusive night flyers, suffer immensely. Their sensitive echolocation systems falter as their prey is attracted to artificial light but they are diverted, bombarded by artificial glow.

Their prey, flying insects of many kinds are also caught in a torturous cycle. Recent research suggests that these insects are not so attracted by the light as their inbuilt navigation is disrupted by the light. Insects that normally orientate their flight to the brightness of the moon mistake artificial lights for the moon and constantly adjust their path as they try to fly away from the light source. It never ends until they collapse to the floor, exhausted.

Even plants have a stake in this battle. Some species flower at night, relying on moonlight and starry skies to guide their pollinators. Excessive light disrupts this delicate dance, affecting pollination and plant diversity. Many take signals from the colour of the dawn or dusk glow, synchronising the photosynthesis and rest periods based on light availability. Plants near street lights grow 10% faster than others, some never reaching maturity as they fail to get signals from dusk that it’s time to flower.
