The rhythm of life is orchestrated by the natural diurnal patterns of light and dark; so disruption to these patterns impacts the ecological dynamics. When she is not writing, she loves watching sci-fi movies on Netflix. As a result, the world is slowly losing the beautiful dark sky view with the moon and the skies as well as other outer space objects. People are also at risk, however, from the direct impacts of living in areas where there are always lights on nearby. The first issue that affects humans and the environment alike is energy consumption. This is because artificial light disrupts our biological clock by altering the production of melatonin - the sleep hormone. Whilst light pollution is currently an issue, it’s important to remember as awareness of the issue grows, people will hopefully respond by making positive changes that will make our planet and skies safer for wildlife everywhere. (And Which Foods to Avoid), Can Squirrels Eat Raisins? Overpopulation. What is a Biome and What are Major Types of Biomes on Earth? Effects.

Light pollution decreases the capacity of the zooplankton to consume algae from the water surface. All Rights Reserved . Artificial light sources hinder opportunities to photograph the night sky and alter the levels of natural light for the amatuer astronomer. In disrupting ecosystems, light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. The researchers are also investigating how individual species living on sea floors are affected by light pollution, while plans for global measurements involving an international team of scientists called Global Artificial Light Ocean Network (GLOW) have been postponed because of the COVID-19 pandemic. Causes of Light Pollution 1. One of the negative effects of industrialization on human activity and the environment is the production of excessive light. 8 Various Types of Environmental Pollution, Why Do White Rabbits Have Red Eyes? Light pollution can cause major adverse health effects. And that light that is scattered upwards is wasted and lost light. Skyglow. Working at nights has become normal for a section of society that has become global and does not want to waste a moment of time. 50% of the light, due to poor shielding, is directed towards the sky, diminishing its view and hence, leading to energy wastage. The researchers from the University of Plymouth spent four nights in 2018 studying the waters of Plymouth Sound and the Tamar estuary, looking for light infiltration – in the form of red, green and blue wavelengths – on the surface of the water, beneath the surface, and on the sea floor. It can confuse the migratory patterns of animals, alter competitive interactions of animals, change predator-prey relations, and cause physiological harm. Skyglow is the name for the reddish-yellow glow in the sky that persists throughout the night due to light pollution in the city below. Here are some of known side effects of light pollution. This leads to an excessive algal bloom that may reduce the quality of water and also disturbs the life of flora of aquatic ecosystems. Ways to reduce light pollution: How do Rainbows Form? Light Pollution is also defined as… “The Excessive, Invasive, or Misdirected Use of Artificial (manmade) Light. In fact, light pollution has an important effect on the trophic chains of nocturnal animals, since it directly affects the ability to hunt and, therefore, feed. Many wildlife animals such as mammals, birds, reptiles and insects are naturally photoperiodic. What are the effects of light pollution? Waste of resources: It costs a lot of money to light up homes, public places, sports and commercial places. For instance, hundreds of wildlife such as deer and zebras are killed on the roads in the evenings since the glares blind and distort their night locomotive aspects. The human eye is equipped to naturally adjust to the day and night patterns so as to see in the right manner. Alteration of the biological clock. In animals and plantsproduces the following consequences: 1. (And Can They Choke on Raisins), Can Squirrels Eat Popcorn? It can create a disorienting experience for the wildlife if there is too much artificial light, especially during night time. Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects. It may seem strange, but excess light is a form of pollution, particularly at night. Hormonal imbalances. Especially, many young people growing up in the city might never experience this beautiful view if people continue to evolve into the night through lighting. What they found is that while the impact of the red wavelengths was minimal, 76 percent and 70 percent respectively of green and blue lights reached the seafloor – these same colors being present in the LEDs that are used along the coast to light up city streets. The air pollution, ecosystem losses and energy waste associated with light pollution are all undoubtedly negative side effects for humanity. Another type of glow is known as ‘gegenschein’: this refers to the way that the sun’s rays illuminate gas and dust in the atmosphere causing a wide-ranging glow. Light pollution can disrupt animal health and behaviour; however, its effects on aquatic invertebrates are poorly understood. Light pollution also changes the natural illumination at night by brightening the skies and leads to the disruption of the ecosystem. What is Oceanography and What Does an Oceanographer Do? Linkages with health and wildlife have been a key focus in the geography literature. In general, artificial lighting heavily impacts and threatens the balance of the ecosystem because numerous wildlife including plants and animals highly depend on the nocturnal and diurnal influences. A study led by the University of Plymouth in the UK has found that the artificial light from coastal cities is affecting as many as three quarters of habitats on their neighboring sea floors. a street light designed to direct light downwards towards the street is more suited for its purpose. /Paul Souders/Getty/VCG. Impact of Light Pollution on Health Light pollution also has clear health and environmental detriments, including harming abilities to sleep, increasing possible cancer, and harming animal behavior, including migration. Light pollution negatively impacts on animal and plant physiology thereby modifying the competitive interactions of the animals, tampers with their migratory patterns, and distorts predator-prey relations. Light pollutant Light pollution is the impact that anthropogenic light has on the visibility of the night sky. Sky glow results from light pollution, or the excess of electric light during the night. The negative effects of light pollution impact many fields of study, including economics, ecology and, of course, astronomy. Light pollution is a side-effect of industrial civilization. A light source that spills or scatters light in all directions is a major source of light pollution. Light pollution, the excessive or inappropriate use of outdoor artificial light, is affecting human health, wildlife behavior, and our ability to observe stars and other celestial objects. Many people don’t realize that it costs lots of money to the power grid system to support the lighting of public places, homes, and commercial places. But light pollution is not like water pollution, which is pollution of water. Light pollution is an artificial light that’s excessive and has a profound effect on astronomy.
