10 Lines on Light Pollution

Light pollution is an outcome of the excessive use of artificial lights during the night due to commercialization, consumerism, and urbanization. The pollution creates constant exposure to light which has a huge impact on the photosynthesis of a plant. The light pollution disrupts our ecosystem and has adverse health issues like stress, anxiety, and insomnia. Over-illumination, glare and sky glow are different types of light pollution that can create navigational problem for nocturnal animals like owl, scorpion and many species of birds.

Ten Lines on Light Pollution

Set 1

1) Light pollution is the pollution caused due to excessive use of artificial light at night.

2) Light pollution is a major side effect of urbanization and industrialization at a rapid pace.

3) It disrupts our entire ecosystem and alters the natural condition of life.

4) Light pollution destroys wildlife by changing the natural lighting of the environment.

5) Changing the light condition in the night has a devastating effect on plants, animals, and nature.

6) Many plants are photosensitive and light pollution can damage metabolism in plants.

7) Light pollution can kill the navigation ability of nocturnal animals at night.

8) The sources of light pollution at night are many like offices, homes, factories, etc.

9) The illumination of the night sky caused by artificial sources of light is known as sky glow.

10) The effects of sky glow can result in the death of birds, sea creatures and nocturnal animals.


Set 2

1) The after-effects of commercialization and consumerism due to the result of human development have led to light pollution.

2) Excessive light pollution has adverse health effects on humans like headaches, stress, and anxiety.

3) Light pollution consumes natural resources in large quantities and costs billions of dollars to the government.

4) An efficient way to tackle light pollution is to switch off the bulbs after use and save electricity.

5) We should use efficient LEDs and CFLs in place of conventional high energy bulbs to curb light pollution.

6) Skyglow creates the problem for astronomers as they are not able to locate the brightest stars in the sky at night.

7) Light pollution has a major impact on reproduction, migration, and communication of animals.

8) It has also deeply impacted the aesthetic beauty of star-studded sky in night by causing sky glow.

9) Light trespass, clutter, glare, sky glow are some of the different types of light pollution.

10) The awareness and education among the people towards the light pollution would help us to curb it down.


Set 3

1) The presence of artificial light in the night environment is termed as “Light Pollution”.

2) Generally, it refers to every artificial light that interferes with natural conditions.

3) Light pollution is a side effect of urbanization and industrialization.

4) In cities, the sky seems to have few stars as they get obliterated by light pollution.

5) It could be classified into four types – urban sky glow, light trespass, Glare, and Cutter.

6) Urban Sky Glow refers to the brightening of the night sky over an urban settlement.

7) Trespass occurs when light falls on an area where it is not intended, needed or wanted.

8) Glare occurs when a very bright light causes discomfort apart from reducing visibility.

9) Clutter, in a way, refers to a mix of urban sky glow, trespass, and glare.

10) Light pollution has detrimental effects on the environment and human health.

Set 4

1) Light pollution occurs when artificial light interferes with natural light and the environment.

2) Urbanization, Industries, buildings, factories, and cars are the main sources of light pollution.

3) Light pollution depends on the population of an area and is directly proportional to the latter.

4) Light pollution can be reduced by using only that much of light which is required.

5) Singapore is declared as the most light polluted country in the world.

6) Light pollution has ill effects on human health which includes headache, fatigue, and stress.

7) Light pollution interferes with the ecosystem and disrupts the food chain and habitat of species.

8) Artificial light confuses animals’ or birds’ natural navigational skills, resulting in damages.

9) Light pollution reduces the visibility of astronomical objects like stars and comets.

10) Strict laws must be enforced to regulate the use of light and to reduce its overuse or misuse.


Light pollution is gradually having a detrimental impact on our ecosystem affecting plants, animals, and humans equally. Light pollution is the outcome of overpopulation of the human race as people are getting increasingly involved in the fast pace of urbanization, industrialization, and consumerism with the passage of time.

The effects of sky glow can also impact agriculture produce. The government, civil societies should create awareness by educating people about light pollution and its causes in order to make the environment safer for living.
