10 Lines on Light Pollution
Light pollution, though less often discussed than air or water pollution, is an important environmental problem in today’s India. As our towns and cities grow, artificial lighting has become a common part of the night-time landscape. However, when this light is excessive, or not directed properly, it changes the natural darkness which is vital for people, wildlife, and even cultural life. In this essay, I will explain what light pollution is, its causes, how it affects not only humans but also the natural world, and how we can reduce its impacts together.What is Light Pollution and Why Has It Increased?
Light pollution happens when artificial light brightens the night sky more than is necessary, disturbingly changing the balance of light and darkness. Several factors in India contribute to this rise. Urbanisation is one of the main reasons. Cities like Mumbai, Delhi, and Bengaluru have seen enormous growth in malls, offices, restaurants, and factories that stay open late. More and more roads are lit through the night, and markets remain busy even at odd hours.Another cause is the increase in decorative lighting, especially for advertisements and events. Huge illuminated hoardings along highways and at crossroads compete for attention. Streetlights, if not properly designed, send much of their light upwards or sideways instead of the ground. Festival times, especially Diwali, add extra brightness when lakhs of homes and neighbourhoods are decorated with string lights, lanterns, and crackers. All these sources together mean that natural darkness barely exists in many places.
Types of Light Pollution
It helps to understand a few basic types: - Skyglow: This is the brightening of the night sky over towns and cities, caused by scattered light, which hides the stars from view. - Glare: Extremely bright or misdirected light—like a blazing tube-light or car headlight—strains our eyes and even creates unsafe conditions on roads. - Light trespass: This is when unwanted light pours into our windows at night, or into parks or forests, disturbing people and animals. - Visual clutter: Multiple bright sources at junctions, markets, or festival venues make nights look busier and more chaotic.These types of light pollution are common in Indian urban areas. At major crossings in cities like Chennai or Hyderabad, the night is as bright as day due to a jumble of streetlights, shops, and advertising boards.
Effects on Environment and Wildlife
Excessive night-time light disturbs many living things. Plants, for instance, depend on length of night and day to flower, rest, and grow. In city parks, constant lighting can cause certain species to flower too early or too late, confusing their natural cycles.Insects such as moths and beetles are particularly affected, often circling streetlights until they die or are easy prey for predators. This reduces pollination – an essential service for crops and gardens. In the Western Ghats or near lakes, bright lights can change the behavior of frogs and fireflies, whose calls and flashes are tuned to dark nights.
Birds, especially those that migrate at night, sometimes get drawn to illuminated towers or tall buildings, colliding with them or losing their way. Nocturnal creatures like owls and bats find it difficult to hunt or nest around bright areas. Even in places bordering the oceans, artificial lighting from resorts can disturb turtle hatchlings that need darkness to crawl safely to the water.
Human and Social Impacts
Light pollution is not just a problem for animals. It affects people too. Bright night lights seep into bedrooms, making it hard for many people to get deep, restful sleep. Scientists call this disturbance of our natural sleep-wake pattern “circadian rhythm”, and it is closely linked to the body’s health and mental wellbeing. Students who do not sleep well may find it harder to focus and do well at school. There is also unnecessary consumption of electricity, which increases both household bills and the load on the country’s power supply. Glare from poorly placed lights at crossings can actually make it more difficult to see, especially for elderly people or drivers at night, leading to accidents.Losing the Wonders of the Night Sky
Perhaps the saddest effect of light pollution is the fading away of the natural beauty of starry skies. In ancient times, Indian poets and sages drew inspiration from the stars and the moon. Gazing upward, our ancestors saw the same constellations celebrated in Sanskrit literature—Dhruva (the Pole Star), Sapta Rishi (the Great Bear), or even the Milky Way, known as “Akash Ganga”. Today, in most Indian cities, far fewer stars can be seen, making it hard for students and amateur astronomers to study or enjoy the universe. Major observatories need to be located far from towns for this reason.Steps to Reduce Light Pollution
There are simple actions that every household and school can take. We should switch off lights and electronic devices when not in use, especially at night. Using lamps that point downwards, with covers or shades, ensures that light goes only where needed and does not spread upwards. Replacing very bright tube lights with warm, lower-wattage LED bulbs reduces both glare and energy use.Schools can arrange “star-gazing nights” by turning off unnecessary lights for a couple of hours and encouraging students to look for constellations. Organising drawing competitions or awareness rallies on light pollution during Diwali week can alert families to the problem. Mapping out the brightest spots around school using simple phone meters is a good group activity.
At the community level, people can suggest to local authorities that streetlights be spaced sensibly and set with timers or motion sensors, so they are bright only when necessary. Temples and event organisers should limit decorative lighting to early evening hours.
10 Original Sentences on Light Pollution
1. Light pollution means the overuse or wrong direction of artificial light, making nights unnaturally bright. 2. It has increased in India because of more cities, busy night markets, and brightly lit advertisements. 3. Festival celebrations, especially Diwali, cause a sudden rise in night-time lighting everywhere. 4. Poorly designed streetlights and upward-facing lamps shine light into the sky needlessly. 5. Wildlife, including birds, insects, and plants, face confusion and harm due to so much night brightness. 6. Too much light at night hides stars, destroying the natural beauty of the sky for everyone. 7. Bright street and building lights disturb people’s sleep and can affect health. 8. Wasted lighting also means more electricity usage and higher bills for families and cities. 9. We can help by choosing shielded lamps, switching off lights when not needed, and using timers. 10. Together, schools, families, and local authorities can act to bring back darker and more peaceful nights.Conclusion
To sum up, light pollution is a modern-day problem in India caused mainly by the careless use of artificial lighting. It harms the environment, wildlife, human health, and even our sense of wonder about the world above. Yet, by taking conscious steps at home, at school, and in our cities—such as shielding lamps, using lower-power bulbs, and switching off lights when not required—we can help restore the calming darkness of night. Small efforts from each of us can revive the joy of seeing the stars and benefit living creatures, making our nights both beautiful and restful once again.---
Tips to Remember: - Divide your points into definition and causes, effects, and solutions. - Use local examples (like Diwali or your neighbourhood) to make your answer stronger. - Keep sentences short and explain difficult terms if needed (for example, circadian rhythm = natural sleep pattern). - Practise reading your answer aloud, using a clear structure for oral or written exams.
