I'm a student at Emerson College and this is my project for my Environment and Humankind (SC-205-02 1), which is taught by Jon Honea. The purpose of the project is to address a specific issue in one of four topics: human population growth, food production in America, global climate change, or energy.
I had some trouble thinking of an idea for the project, so I took Jon’s advice and did a project with activities I enjoyed outside of class(photography and blogging). I also wanted to do research on an environmental issue that doesn’t get a lot of coverage. Pollution has always piqued my interest and I stumbled upon light pollution.
In my project, I took pictures of examples of light pollution and waste in Boston. I also provide an explanation of light pollution and some different ways to reduce light pollution.

What is Light Pollution?
Light pollution or photopollution is the use of excessive or obtrusive artificial lighting. This type of pollution is especially relevant in cities such as Boston. Light pollution wastes energy, negatively affects both animal and human health and psychology, and disrupts ecosystems.
According to the U.S. Natural Park Service, which works under the U.S. Department of the Interior, light pollution is "Principally, the illumination of the night sky caused by artificial light sources, decreasing the visibility of stars and other natural sky phenomena. Also includes other incidental or obtrusive aspects of outdoor lighting such as glare, trespass into areas not needing lighting, use in areas where or at times when lighting is not needed, and disturbance of the natural nighttime landscape."
There are four types of light pollution. The first is sky glow, which is the brightening of the night sky in urban or inhabited areas. Sky glow is a major issue within cities. Light trespass, the second type, occurs when light falls in areas unintentionally or in areas where the light is unwanted or unneeded. The third type is bright light that reduces visibility and causes discomfort. Lastly, clutter is the grouping of excessively bright lights. Light clutter is another major issue in urban areas.
