Question

Essay on light pollution (not more than 100 words )​

Answer 1

Answer:

Light pollution is a type of pollution. It is defined as “any adverse (or bad) effect as a result of man-made lights.” Usually, this means too much light. Several species, including plants and humans, are badly affected by light pollution. Most people have never heard of light pollution, and those who have usually don’t care, or do anything about it. Light pollution costs Americans billions of dollars every year.

There are five kinds of light pollution:

• Light trespass
• Over-illumination
• Clutter
• Glare
• Sky glow

Sky glow usually has more of an effect on the environment than light trespass and glare, but all of them are a major problem to people today.

Sky glow is the kind of light pollution that prevents people from seeing stars and other deep-space objects. This causes birds to not be able to migrate to the right place because they can not follow the moon and stars. Sky glow also prevents astronomers from seeing dim objects.

Light trespass is when light being used by a person goes into the property of another. Although light trespass is not an environmental issue, it is still light pollution.

The third kind of light pollution, glare, has different kinds. The first, disability glare, is the loss of visibility because of too many lights. Discomfort glare is when the lights cause pain.

Effects on animals

Light pollution stops migrating birds from having any way of seeing the moon and stars that they need to use to navigate the direction of their migration, therefore not being able to migrate to the correct place. Also, sea turtles do not come to shore and nest as often, because they are afraid of the lights. It also affects animals eyes as a flash of camera weakens the eyesight of animals.

Effects on humans

Glare causes sleep problems in humans. For example, too much light in an apartment shining in from a nearby billboard will disturb their sleep. Science, too, is being affected by light pollution. Astronomers have no way of observing or making discoveries with too much light to block the night sky. Light pollution also causes headaches when light directly falls into our eyes and affects the sensory nerves.

There are now several groups that are trying to prevent light pollution. Light pollution first made news in 1964, when an observatory was specially placed just to avoid light pollution. However, it wasn’t brought to the attention of most people until June 6, 2002, when the Czech Republic passed the world’s first light pollution law. Since then, light pollution is slowly being recognized by the general public as a major problem.

Also government should pay attention for advertisements, which produce the greatest amount of light.

Answer 2

Unwanted or excessive artificial light is referred to as light pollution. Light pollution, like noise pollution, is a waste energy source that can have negative consequences and damage environmental quality.

Explanation:

Light Pollution:

• Humans are diurnal (active primarily during the day) species, which is a basic evolutionary truth.
• Humans have eyes that have evolved to live in the light of the sun. We've made the darkness welcome us by flooding it with artificial light. Damming a river is similar to this type of engineering.
• It has advantages, but it also has drawbacks. Light pollution is one of these impacts.
• Light pollution (also known as photopollution or luminous pollution) is obtrusive (bothersome), misdirected, inappropriate, or excessive artificial light that happens at night.
• Urban Sky Glow, which is the brightening of the night sky over human regions, is one example of light pollution.
• When light falls where it isn't supposed to or needs to fall, this is known as light trespass. Visibility can be reduced by glare, which is caused by extreme brightness and high levels. Light sources that are brilliant and excessive, as well as clutter. In over-lit urban areas, certain light sources can be found.
• The brightening of the night sky reduces the visibility of stars and planets.

Individual creatures and the effects of light pollution:

• Light pollution's most typical effect is that it disrupts biological cycles and activity.
• We interrupt our own and other organisms' sleeping cycles as a result of all our artificial light.
• This is particularly problematic for nocturnal species that awaken at dusk. They are more vulnerable to predators as a result of the artificial lighting, and they have less time to find food. Organisms rely on their genes to inform them when to get up or sleep, but with all of our artificial lights, this can be confusing.
• When people go to other time zones, they may notice that everything is different and their minds and bodies are confused.
• Light pollution affects mammals as well, particularly nocturnal species such as bats, coyotes, and bats.
• Night-migrating birds rely on the light reflected by the moon and stars to navigate through the darkness. Because they were taken off guard by all the lights, they become confused and may become stuck in an urban area.

Types of light pollution:

Urban Sky-glow:

• Sky light is a phenomenon that occurs in major cities. It's the glow that may be seen in the evenings over numerous cities and towns.
• The brightening of the night sky is known as urban sky glow. It occurs when artificial light from poorly aimed and engineered light sources escapes into the atmosphere.
• While travelling through the atmosphere, it is scattered by particles (pollen, germs, dust, spores, mineral particles) or water droplets. The light is reflected, masking the background stars and giving the night sky a hazy haze.
• Astronomers are concerned about this form of light pollution because it casts a hazy haze across the night sky.

Clutter:

• Excessive light groups are known as light clutter.
• These light clusters can cause confusion, attention from objects, and even accidents. Clutter light pollution is generated by things like street lights, which can be hazardous to people driving since they can distract drivers.

Glare:

• Excessive and uncontrolled light causes glare, which is a visual sense.
• Streetlights, car-yard lights, and security lights can all cast a glare directly into your eyes, causing pain.
• This makes it difficult for the eye to respond to shifting levels of illumination adequately, impairing night vision.

Brightness:

• The presence of bright sources in a person's field of vision that can cause discomfort, impairment, or blindness glare.

Reduce light pollution:

• We may reduce light pollution by conserving energy at home, turning off lights that aren't in use, and so on. By doing so, we can all help to reduce light pollution.  

• We can also lessen light pollution in larger amounts by turning off a few streetlights and welcoming the darkness.

• We can also employ intelligent lighting to reduce the impact by using dimmer or timer lights, as well as wavelength light with a red or yellow tint.

• We should also replace small, low-quality lamps with brighter illumination so that we may use as little electricity as possible while still being able to see well enough to stroll down the street.  

• We could also make use of efficient sources found in and around companies and residences.

• We can get enough light from a low-wattage light bulb in most of the places we go. When using higher power light bulbs, ensure sure the bulb is protected to prevent light from being wasted.
