Light pollution is the presence of any unwanted, inappropriate, or excessive artificial lighting. [1] [2] In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind ...
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...
Data flowcharts, showing controls over a data-flow in a system; System flowcharts, showing controls at a physical or resource level; Program flowchart, showing the controls in a program within a system; Notice that every type of flowchart focuses on some kind of control, rather than on the particular flow itself.

Light pollution is the impact that anthropogenic light has on the visibility of the night sky. It also encompasses ecological light pollution which describes the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.

The eye facets of Platycnemis pennipes collect light directly or incidentally. That gives environmental information to the insect. Polarization is a property of light waves that describes the orientation of their oscillations. Polarized light pollution [1] is a subset of the various forms of light pollution referring specifically to polarized ...
Mexico City at night, showing skyglow A map from 1996 to 1997 showing the extent of skyglow over Europe. Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution.
Another characteristic of urban areas is light pollution. One of the well known consequences of light pollution is the attraction of insects. Before the presence of human light, the only source of light at night was the moon. Insects fly with a fixed angle to the moon to be able to fly in a straight line. Our light sources, however, are very ...
The representation of such a system can be supplemented by one or more flowcharts, which show the sequence of one of the flows in one direction, or any of the control flows to manage the system. The physical movement of objects from one location to another can also be visualized in a mix of maps and flowchart or sankey diagram , which are ...
