Light pollution

Most of us are familiar with air, water, and land pollution, but did you know that light can also be a pollutant? Not many people know about this kind of pollution. Light pollution is the inappropriate or excessive use of artificial light and it can have serious environmental consequences for humans, wildlife, and our climate. Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminates sporting venues.

The fact is that much outdoor lighting used at night is inefficient, overly bright and, in many cases, completely unnecessary. This light, and the electricity used to create it, is being wasted by spilling into the sky, rather than focusing on the actual objects and areas that people want illuminated. For three billion years, life on Earth in a rhythm of light and dark that was created solely by the illumination of the Sun, Moon, and Stars. Now, artificial lights overpower the darkness and our cities glow at night. It disrupts the natural day-night pattern and shifts the delicate balance of our environment. Light pollution has negative impacts. It increases energy consumption, disrupts the ecosystem and wildlife and harms human health. Fortunately, concern about light pollution is rising dramatically. A growing number of sciences, homeowners, environmental groups and civic leaders are taking actions to restore the natural night.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.
