Light Pollution Speech: If we went before a little more than 100 years ago, we could walk outside at night in a city, and we could see the Milky Way galaxy arch across the night sky.
We could see how thousands of stars were parts of our everyday life and how they were inspiring artists like Van Gogh or musicians like Gustav Holst or writers like William Shakespeare.
Now, as we are allowing artificial lights to wash out our starry night skies, we are losing contact with our cultural heritage which has made us who we are. We are also losing connection with what could inspire their future generations.

Long Speech On Light Pollution 500 Words In English
In today’s disrupted environment, light pollution has become a serious threat particularly to nocturnal wildlife, i.e. animals living in the dark. Light pollution has many negative impacts on plant and animal physiology.
It can bewilder the translocating patterns of animals, change fierce interactions of animals, alter predator-prey relations, and cause harms physiologically. The rhythm of life is arranged by the natural non-nocturnal patterns of light and dark. So disruption to these patterns affects the ecological dynamics.
You will be surprised to know that with more than half of the world’s population now living in cities, 3 out of every four people in cities have never experienced the astonishing thing of natural dark skies.
Concerning bad health effects, many species, especially humans, depend on natural body cycles which are known as circadian rhythms. They are dependent on the production of melatonin, which is regulated by light and dark also. If humans are exposed to light while sleeping, production of melatonin can be put down.
This less production of melatonin can lead to various sleep disorders and other health-related problems such as increased headaches, worker fatigue, medically defined stress, different forms of obesity due to lack of sufficient amount of sleep and increased anxiety.
And there are risks of a couple of types of cancer. There are also bad effects of flame on ageing eyes. Health effects are not caused by only over-illumination or excessive exposure of light over time, but also the inappropriate insubstantial composition of light. This composition of light is certain colours of light.
If we talk about the wastage of energy, we must know that lighting is blameworthy for at least one-fourth of all electricity consumption around the world. Over illumination can comprise energy wastage, especially in an upward direction of lighting at night. Wastage of energy is also a waste in cost and carbon footprint.
The good news is that light pollution can be reduced quite easily by protecting lights properly. We should only use a light when and where it is needed. By only using the required amount, by using energy-efficient bulbs, and by using bulbs with appropriate spectral power distributions for the task at hand, we can easily reduce light pollution.
Speaking with my clinical knowledge, the three main types of light pollution include glare, light trespass and skyglow. Glare from unprotected lighting is a threat to the health of human beings, especially the older you become. Glare light breaking up in the eye can cause loss of contrast, and it can blind you temporarily. This glare leads to unsafe driving conditions, for instance.
Light trespass is caused when unwanted light enters one’s property. For example, we can say, shining unwanted light into a bedroom window of a person who is trying to sleep is light trespass.
Skyglow is defined as the glow effect that can be seen over populated areas. Skyglow is the combined form of all the reflected light and upward-directed light escaping up into the sky. If we shield lights, then it can significantly reduce all three of these types of light pollution.
Short Speech On Light Pollution 150 Words In English
We, humans, are active mainly during the day. Human eyes are adapted to living in the sun’s light. We experience the nights with the help of artificial light. It has benefits, but also negative impacts. These negative impacts are light pollution.
Light pollution (which is also known as photo pollution or luminous pollution) occurs at night and is noticeable, misdirected and inappropriate. Light pollution is caused due to excessive artificial light.
Different elements of light pollution are: Urban Sky Glow, i.e. brightening of the night sky over inhabited areas, Light Trespass, i.e. when light falls where it is not needed to fall, glare, visual discomfort caused by excessive brightness and high levels can decrease vision power, Clutter, light sources which are bright and excessive.
These light sources are generally found in over-lit urban areas. It is the brightening of the night sky, and it decreases the view of stars and planets.
Thank you.

Question 1.
Describe one negative impact of light pollution.
Answer:
Light pollution has many negative impacts on plant and animal physiology.

The rhythm of life is arranged by the natural non-nocturnal patterns of light and dark. So disruption to these patterns affects the ecological dynamics.
Question 2.
What are the three types of light pollution?
Answer:
The three main types of light pollution include glare, light trespass and skyglow.
Question 3.
What is skyglow?
Answer:
Skyglow is defined as the glow effect that can be seen over populated areas. Skyglow is the combined form of all the reflected light and upward-directed light escaping up into the sky. If we shield lights, then it can significantly reduce all three of these types of light pollution.
