Light pollution is not only a hinderance to astronomy, but it also impacts us directly. Each of us can implement practical solutions to combat light pollution locally, nationally and internationally.The good news is that light pollution, unlike many other forms of pollution, is reversible and each one of us can make a difference! Learn about the major types of light pollution, their impact on human health, and how the worldwide glow from artificial light may continue to grow.Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. IDA educates the public and certifies parks and other places that have worked to reduce their light emissions.
However, like carbon dioxide emissions and plastic, too much of a good thing has started to negatively impact the environment. This light, and the electricity used to create it, is being wasted by spilling it into the sky, rather than focusing it on to the actual objects and areas that people want illuminated.With much of the Earth’s population living under light-polluted skies, over lighting is an international concern. There is a global movement to reduce light pollution, and everyone can help.Boats, buildings, street lights, and even fireworks contribute to the light pollution in Victoria Harbor, Hong Kong. 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.

Birds are also affected by this, and many cities have adopted a “Lights Out” program to turn off building lights during bird migration.Even in places meant to provide protected natural habitats for wildlife, light pollution is making an impact. © 1996 - 2020 National Geographic Society.

Now, artificial lights overpower the darkness and our cities glow at night, disrupting the natural day-night pattern and shifting the delicate balance of our environment. © 1996 - 2020 National Geographic Society. IDA has many valuable Andre Gabrielli, National Geographic Society Being able to see thousands of stars was part of everyday life, inspiring artists like Van Gogh or musical composers like Holst or writers like Shakespeare. The light pollution map has two base layers (road and hybrid Bing maps), VIIRS/World Atlas/Clouds overlays and a point feature overlay (SQM, SQC and Observatories).

This became glaringly obvious when the Sky glow is the brightening of the night sky, mostly over urban areas, due to the electric lights of cars, streetlamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Large numbers of insects, a primary food source for birds and other animals, are drawn to artificial lights and are instantly killed upon contact with light sources.
More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow. Learn about the major types of light pollution, their impact on human health, and how the worldwide glow from artificial light may continue to grow. Light pollution can be detrimental to the health of people and animals in the area. A growing number of scientists, homeowners, environmental groups and civic leaders are taking action to restore the natural night. Less than 100 years ago, everyone could look up and see a spectacular starry night sky.
But a growing body of evidence links the brightening night sky directly to measurable negative impacts includingLight pollution affects every citizen.
