The night sky, once a canvas of stars, is slowly disappearing. In cities — and even in far-off rural areas — the stars have faded behind a constant veil of artificial light. What was once normal — the clear view of the Milky Way or the slow dance of constellations — has become a rare experience. This is the result of a growing environmental problem known as light pollution.
Light pollution is an environmental issue caused by the excessive or misdirected use of artificial lighting. Sources include streetlamps, buildings, cars, and billboards that shine into the sky instead of toward the ground. This constant brightness erases natural darkness and severely impacts nighttime ecosystems. Though it leaves no smell or trash, its environmental impact is silent and long-lasting.
This form of pollution disrupts the natural balance of ecosystems. Nocturnal animals become disoriented, migration patterns are interrupted, and insect populations decline. Even plants struggle to grow properly under constant artificial light. This invisible threat has now reached deep into forests, shorelines, and mountain towns — damaging biodiversity without drawing much attention.
Humans are affected too. Artificial light exposure during nighttime interrupts sleep patterns, affects mental health, and even weakens the body’s ability to regulate hormones. These environmental effects cross into public health, showing that light pollution isn’t just a scientific issue — it’s a growing risk to communities.
The worst part is how easily the problem spreads. Light travels. What happens in one city can affect skies many kilometers away. Even areas that used to enjoy dark skies now see skyglow — a clear sign of light pollution expanding beyond urban zones.
Yet this is an environmental crisis we can still reverse. With smarter, lower, and warmer-toned lighting, energy-efficient fixtures, and awareness campaigns, the night sky can be restored. Unlike many environmental problems, this one requires no large-scale cleanup — just smarter choices.
We are not losing the stars because they vanished — we are drowning them in unnecessary light. The sky is part of our environment too. And like forests, oceans, and air, it needs protection.
