  1. WHAT CONSEQUENCES EFFECTS Photo pollution/ Luminous pollution

  2. Excessiveartificiallight increased brightness • The International Dark-Sky Association (IDA) adverse effect : • sky glow • glare • light trespass • light clutter • Decreased visibilyty • Energy waste

  3. Indoor = lighting in houses or apartments (North America, Europe, Japan, Middle East, North Africa) • Outdoor (main pollutants): • more necessary (roadside lamps, traffic lights, vehicle lights, road sign lights, emergency vehicle lights...) • Less necessary (store, commercial sign lights, the lights that enlight statues and buildings...)

  4. Energy waste light bulbs energy resource deficiency wars dishwashers energy crysis save energy: energy saving washing machines refrigerators

  5. sky observing interference telescope efficiency dark sky La Silla observatory in Chile 6 hundred kilometres away from light Hinder to acquire knowledge

  6. Types of pollution • Light trespass • Glare: • Blinding glare • Disability glare • Discomfort glare • Light clutter • Sky glow

  7. Human health Fluorescent lighting  elevate blood pressure by 8 points, increased stress & fatigue worker errors over-illuminating and bad planning of lighting (not light pollution)

  8. Animals • Changed mood & behaviour • confuse animal navigation • alter competitive interactions • change predator-prey relations • more aggressive

  9. Disruption of ecosystems • It can be: • beneficial • neutral • damaging Spiders

  10. Solutions • adjusting light’s intensity • turning lights off • improving lighting fixtures • adjusting the type • evaluating the necessity of lights

  11. Organisations and campaigns • the IDA • Globe at Night (global) • ‘’Nebo ponoči’’ in Slovenia • Earth Hour

  12. Not really dangerous just disturbing and hindering
