The Dark Sky Revolution: How Europe is Reclaiming the Night
Belgium, often brightly illuminated when viewed from space, is at the forefront of a growing movement to restore darkness to its natural state. A radical project in the Entre-Sambre-et-Meuse national park, near the French border, is seeing 75 “pointless” streetlights permanently switched off, marking a significant step towards mitigating light pollution and protecting biodiversity. This initiative isn’t isolated; it’s part of a wider European trend recognizing the detrimental effects of artificial light on the environment and human health.
The Cost of Constant Illumination
For over a century, the expansion of electric lighting has transformed our world, but at a cost. Research increasingly demonstrates that illuminating the night sky disrupts the natural rhythms of a wide range of species, impacting their feeding, reproduction, and navigation. Insects, birds, and amphibians are particularly vulnerable. In France, an estimated 2,000 billion insects are killed annually by public lighting. The problem is global, with 80% of the world’s population now living under light-polluted skies.
Beyond Biodiversity: Rethinking Safety and Security
The debate surrounding streetlights often centers on safety. Residents, like André Detournay, 77, of Mazée, express concerns about personal security and theft. “I walk here with my dog and it makes me feel safe,” he says. But, studies challenge the assumption that more light equates to more safety. Research in England and Wales found that reduced street lighting didn’t significantly impact crime rates or road collisions. The perception of safety, it seems, doesn’t always align with actual safety.
A European-Wide Shift Towards Darkness
The Belgian project is mirroring initiatives across Europe. Thousands of communes in France are switching off public lighting mid-night to conserve energy and reduce light pollution. At the EU level, guidance is being developed to create dark corridors for wildlife and reduce artificial light. The UK is seeing increased awareness campaigns, and cities in the US are exploring ways to reduce sky glow. This coordinated effort signals a fundamental shift in how we perceive and manage nighttime environments.
From Streetlights to Stork Havens: Repurposing Infrastructure
The removal of unnecessary streetlights isn’t just about eliminating a problem; it’s about creating opportunities. In the Entre-Sambre-et-Meuse park, disused electricity pylons are being repurposed as nesting sites for white storks, a species that has seen a remarkable resurgence in the region – with nearly 800 sightings in 2025. These retrofitted pylons, costing around €500 each, provide a safe haven for the birds, demonstrating a creative approach to environmental restoration.
The Future of Nighttime Environments
The project in Belgium, allocating €308,000 to restore nighttime darkness, treats it as a beneficial act for nature, comparable to restoring a pond or woodland. This approach highlights a growing recognition of the intrinsic value of darkness. Extending this infrastructure to other parts of Europe is the next step, with collaborations already underway with French colleagues.
FAQ: Light Pollution and Dark Skies
- What is light pollution? Excessive or misdirected artificial light.
- Why is light pollution harmful? It disrupts ecosystems, impacts human health, and wastes energy.
- Does turning off streetlights increase crime? Studies show no significant correlation between reduced street lighting and increased crime rates.
- What can individuals do to help? Use outdoor lighting only when necessary, shield lights to direct them downwards, and advocate for responsible lighting policies.
Did you know? More than half of all insects are active at night, making them particularly vulnerable to the effects of light pollution.
Pro Tip: Consider using motion-sensor lights for outdoor security. They provide illumination only when needed, minimizing light pollution.
