Light Pollution

"...whose effects scientists are only now beginning to study.  Light pollution is largely the result of bad lighting design, which allows artificial light to shine outward and upward into the sky, where it's not wanted, instead of focusing it downward, where it is.  Ill-designed lighting washes out the darkness of night and radically alters the light levels - and light rhythms - to which many forms of life, including ourselves, have adapted.  Wherever human light spills into the natural world, some aspect of life - migration, reproduction, feeding - is affected...Of all pollutions we face, light pollution is perhaps the most easily remedied.  Simple changes to lighting design and installation yield immediate changes in the amount of light spilled into the atmosphere and, often, immediate energy savings."

See some streetlights on 24 hours a day - help us get them turned off during the day

As you may notice, there are many streetlights on during the day, sometimes even whole streams of streetlights on one side of the road that are on all day, every day.  Use this form to inform Enersouce Mississauga to get these streetlights fixed so they are only on during the night.  Make sure the tell them that the lights are on during the day, as they concentrate on lights that are off during the night.  REPORT STREETLIGHTS ON!
