Light pollution: the good, the bad and the ugly

According to current estimates, the UK consumes more than 100 million pounds of energy annually. £ 100 million!

This is enough money to buy two luxury homes in the center of London, 1000 Aston Martin, or if you like Richard Branson, Caribbean private island

As an example, sky light, spilled light and glare brighten the night sky, it is divided into two types, discomfort and disturbance (details are here)

We are more concerned about bad healthy glare; this type is so brighter that you want to be away from it (obstacle glare can affect your ability to see a strong light source)

Since the introduction of the Clean Community and Environmental Law in 2005, unnecessary artificial light intrusion has been classified as legal nuisance. In other words, local governments have a legal obligation to investigate mild pollution violations as well as noise and air pollution problems.

Please do not light excessively. In order to reduce superior light, as explained by ILP in the "Guide to Guidance", GN 01: 2011 (Read the full text!)

Partial night switching or dimming is an energy-saving and cost-effective option that should definitely be considered at the design stage. For example, if an area is not used even after a certain period of time overnight, do you need the same level of illumination as the peak time?

Anti-glare occlusion minimizes unnecessary light leakage and lights the necessary place. They are another simple consideration at the design stage of the project - but they can also be retrofitted to the installed solution. Do not worry about ugly light as the shield is not noticeable

Finally, consider the proper mounting height and slope of the luminaire. Generally, if the installation height is increased or the inclination angle is increased, the light tends to leak more than when installed with a low zero lift. Floodlight is one of the biggest factors not necessary for unwanted light when placed in the wrong position

Since light damage plays an important role in waste of energy, taking necessary measures to prevent light damage was not so important.

Unfortunately we see that it is worse and terrible than good news when we see the benefits, bad things, and ugly on ocean plastic contamination. As the old sailor says, "Before my fearful story is told, the heart of my heart", we are talking about marine animals that are felt the fatal influence of plastic contamination with us It is impossible to spend. It is important. The Philippine Greenpeace created creative and powerful artwork to attract public attention and encourage recycling activities. The full-size 15 meter long whale is composed entirely of plastic waste, causing unnecessary plastic consumption problems in front of the masses. Artwork is uncomfortable and frustrating, just what you need.

So far, we have not received much benefit from 'good, bad, ugly' plastic contamination, so after some news of frustrating news, I recently talked about cleaning the world's largest beach in Mumbai, India I returned. . Twenty years later, the turtle once again made nests on the beach and gave a wonderful result. We hope that you will not miss this inspiring story, if you do not, this is the second chance, see: rare sea turtle is the world's largest beach cleanup I will return later.

The turtle that emerges from the beach's nest is also a victim of light harm. It is a common mistake that turtles hatching are attracted to the moon. Instead, they discover the ocean in the dark away from the dunes and the dark outline of their vegetation. It is an act of artificial light interference. However, reproductive activity and breeding phenology of cockroaches are inspired by the moonlight. Underage seabirds may be lost in the direction of light when flying off the nest to the sea. Amphibians and reptiles are also affected by light damage. The light source introduced during normal dark period may disturb the level of melatonin production. Melatonin is a hormone that regulates the physiology and behavior of the photoperiod. Several species of frogs and crickets use "compass" which depends on light to direct movement to the breeding ground.
