As an example, the following cases can be mentioned: Reduction of melatonin production in the body; hormone responsible for growth in the body. This causes birds to not be able to migrate to the right place because they can not follow the moon and stars. Sometimes, these stor… Another cause of pollution is the ignorance and lack of awareness of people’s people who do not save energy consumption light and abuse illuminating spaces that are not transited at home or in populated places. Certain gases in the atmosphere can cause air pollution. Some of the most suggested recommendations for the prevention of this type of pollution are: Within the different types of light pollution, we can mention the following: There are many examples of the presence of light pollution worldwide. Air Pollution is the presence of harmful elements in the air. There are various causes to the spread of pollution of environmental air around us. Leaving the lights switched on for the whole night is not only contributing to the causes of light pollution but it is also an example of wasting energy (Check – energy Saving tips ). Light pollution is thus linked to the disruption of the natural habitat and negative impacts on human health. Over-illumination, light placement and glares most commonly contribute to the light pollution in the sky. Modification of the natural behaviour of birds and produces alterations in their migrations and reproductive cycles. Think of a large, well-known store at night, and you'll probably notice that its store name is lit up. Also, some businesses with large windows purposely leave all their lights on at night. Light pollution is a side effect of the industrial civilisation and the result of ineffective lighting. Alteration of the life cycle of nocturnal animals. In disrupting ecosystems, light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. This is quite intuitive since overpopulation usually leads to a higher population density. Over-illumination 4. Light pollution is caused by inefficient or unnecessary use of artificial light. disruptive effect on natural cycles and inhibits the observation of stars and planets a street light designed to direct light downwards towards the street is more suited for its purpose. Promote this type of information to raise public awareness and avoid light pollution. Poorly recycled, dumped in landfills is the main cause. The main cause of light pollution is the misuse of artificial lightin streetlights, projectors, spotlights, lamps, etc., which let a large part of their luminous flux escape into the sky. Each of us can implement practical solutions to combat light pollution locally, nationally and internationally. It is also an effective use of energy in the form of electricity.

Light pollution, unwanted or excessive artificial light.Like noise pollution, light pollution is a form of waste energy that can cause adverse effects and degrade environmental quality. Light pollution is the undesirable use of artificial light that causes problem such as the alteration of natural light level in the outdoor environment, disruption of the natural habitat, etc. It can confuse the migratory patterns of animals, alter competitive interactions of animals, change predator-prey relations, and cause physiological harm. These are more durable and generate less impact in the sky. Light pollution definition is - artificial skylight (as from city lights) that interferes especially with astronomical observations. Many mammals, insects, birds, and reptiles are photoperiodic meaning their movement, mating, growth and development, and eating cycles are regulated by natural light patterns. Ozone is also a greenhouse gas that can be both good and bad for our environment. Plastic pollution causes. For example, some people have security floodlights that come on at night so it's not completely dark around their home. For example, in cities, a gas called ozone is a major cause of air pollution. There are five kinds of light pollution: 1. This type of pollution is little known in many countries and for this reason, the planet is now faced with the disastrous consequences it produces. This is because when an open bulb releases light, most of it is directed upward, instead of focusing on a specific spot. Unlike other forms of pollution, light pollution has not been regarded as an important issue until lately.Specifically, light pollution has been realized due to some of its effects. A growing number of scientists, homeowners, environmental groups and civic leaders are taking action to restore the natural night. I am often taken aback by what I hear people say about light pollution. Too many light sources that stay on for extended periods of time have a significant impact on light pollution. Cars, trucks, jet airplanes and other combustion engine vehicles cause air pollution. This in turn leads to a higher level of light pollution. Excessive lighting generates energy and CO2 costs in the ecosystem. Electricity. Poorly designed residential, commercial, and industrial outdoor lights also contribute significantly to light pollution. Avoid the use of light or laser cannons in the sky. Turn on the light only when necessary and turn it off in places where no one requires it. Light pollution can accumulate significantly within highly populated areas, causing a number of issues within the natural environment. With respect to adverse health effects, many species, especi… Poorly designed streetlights with high powered bulbs cause glare and light trespass, which decreases visibility on the road in front of drivers. 1. As a consequence, it upsets the activities and natural cycles of wildlife and also affects the welfare In the case of humans, it can have the following negative health effects: In animals and plants produces the following consequences: In addition to these negative effects, it should be noted that it also affects the astronomical study of the sky, generates many economic costs, climate change and the energy crisis worldwide. Very often, people act carelessly and illuminate very bright lights at homes and business places – no matter what the hour.2.
