When there is too much light, too little light, or the wrong kind of light present it can disrupt the natural harmonies and metabolic cycles of life forms on Earth. While worrying about whether the ground worm is confused as to whether it is night or day doesn’t seem like an issue, consider that human beings have metabolic systems that are also highly light dependent. We are as responsive to light as a plant that turns its bloom towards the sun. In fact, Seasonal Affective Disorder(SAD) is thought to be caused by a sharp decrease in exposure to natural light.
causes:-Poor Planning – The placement of signage and street lights is planned by engineers, if they do not take into account the effect placement has on the surrounding environment they can create glare, light trespass and light clutter.
Irresponsible use – You may love Christmas lights but leaving them on all night is a form of pollution, as is leaving a room with the lights still on or setting the timers on street lamps and not adjusting the timer for the season. Not actively choosing to minimize energy waste is a huge source of light pollution. Overpopulation – That is really a zoning issue. Too many businesses, or too many residences, grouped in one area can cause light pollution of many kinds.
Effects:-Animals – Lights can attract or repel animals and insects. Most animal life functions on a diurnal or nocturnal system that is thrown out of sync by light pollution. This can place entire species in danger, or attract unwanted species into human areas.
People – The wrong kind of light, or too much light has been proven to have an impact on your health and quality of life. Light pollution also increases danger to people as it can interfere with important navigational systems for trains, planes and even automobiles.
The Earth – The Earth’s ecosystem is dependent on cycles of natural light. Sky Glow alone can cause a loss in growth protection as the reflected light off the atmosphere will prevent the natural UV rays from reaching the Earth. This disrupts growth and decay cycles that our food, air and water supply is dependent on.
conservation:-There are two basic approaches to solving light pollution – planning and education. Planning means more consideration about how areas are zoned and where lights are placed. It also means changing the types of lights used within the home, signs and street lamps to more efficient bulbs, and with a light output that is not so disruptive. Education is also key. The more people understand the importance of turning off lights to conserve energy and reduce light pollution the faster change will be seen.
