Svetlobno onesna\u017eevanje je emisija svetlobe iz umetnih virov, ki pove\u010duje naravno osvetljenost okolja. Strokovnjaki ocenjujejo,  da v Evropi na novo osvetlimo pribli\u017eno 1 kvadratni kilometer na dan. Ljudje zaradi brezbri\u017ene uporabe umetne svetlobe postopoma vodijo, do prihodnosti, kjer bo no\u010d tako svetla, kot je danes dan. Torej bomo lahko knjige brali tudi pono\u010di brez lu\u010di. Ta prihodnost ironi\u010dno ni svetla in moramo narediti nekaj, da se to spremeni.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Re\u0161evanje problema se za\u010dne s tem, da se lotimo naj\u0161ibkej\u0161ega \u010dlena. V na\u0161em primeru je to osvetljevanje javnih objektov, kot so cerkve, spomeniki in ogla\u0161evalni panoji. Ve\u010dina teh objektov je osvetljena od spodaj navzgor. Pri temu gre pogosto od 60% do 80% celotnega svetlobnega toka mimo fasade v nebo in okolico.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ta pobegli \u017earek zmoti bioritem mnogih \u017eivalskih vrst in prav tako ljudi. Medtem ko svetloba privla\u010di nekatere \u017eivali in jih s tem ujame v neskon\u010dno kro\u017eenje okoli svetlobe, druge odganja in s tem zmanj\u0161uje njihov naravni habitat.<\/p>\n\n\n\n

Svetloba ima najve\u010dji vpliv na \u017eu\u017eelke, to pa spro\u017ei veri\u017eno reakcijo in s tem vpliva tudi na druge \u017eivalske vrste, kot je netopir, ki je odvisen od prehranjevanja z \u017eu\u017eelkami. \u017du\u017eelke uporabljajo Luno, kot vodilo saj je vir svetlobe.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\u010clovekovo mno\u017ei\u010dno ustvarjanje virov umetne svetlobe zmoti tako dnevni ritem in selitve \u017eu\u017eelk, kot prehranjevanje in razmno\u017eevanje, saj \u017eu\u017eelke to svetlobo vidijo, kot ne\u0161teto Lun, ki v ve\u010dini vodijo do njihove smrti. Mno\u017ei\u010dno umiranje \u017eu\u017eelk in osvetljenost javnih objektov, neposredno vplivajo na netopirje.<\/p>\n\n\n\n

Osvetljenost javnih objektov vpliva na to, da se samice netopirjev na lov odpravijo kasneje kot sicer in tako zamudijo ve\u010derni mrak, ko je naokoli najve\u010d \u017eu\u017eelk in bi se lahko najedle. Slab\u0161e nahranjene matere slab\u0161e skrbijo tudi za mladi\u010de. Posledi\u010dno rastejo po\u010dasneje, zato bodo tudi te\u017eje pre\u017eiveli.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Prav tako svetloba negativno vpliva na \u010dlove\u0161ki ritem ter zdravje. Za na\u0161e zdravje je izrednega pomena bio – ritem dneva in no\u010di, kar imenujemo cirkadialni ritem. Zaradi prevelike koli\u010dine umetne svetlobe med spanjem, pride do prekinitve tvorjenja melatonina, imenovanega tudi hormon spanja.<\/p>\n\n\n\n

Melatonin deluje antioksidativno in antikancerogeno ter vpliva na kakovost na\u0161ega spanja ter dobrega po\u010dutja. Pomankanje melatonina lahko pripelje do razli\u010dnih bolezni na stara leta.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Menimo, da moramo zmanj\u0161ati nepotrebno uporabo svetlobe, \u010de \u017eelimo obdr\u017eati vse vrste \u017eivali ter zmanj\u0161ati dele\u017e bolezni povezanih z umetno svetlobo. Verjameva pa tudi, da se vsi bojimo prihodnosti v kateri je omejen dostop do energije. Nekaj najinih re\u0161itev je: bele LED svetilke, ki so velika gro\u017enja (saj sevajo modro svetlobo, ki prekine tvorbo melatonina \u017ee ob majhni izpostavljenosti), nadomestimo s svetili, ki odsevajo toplo (rumeno) barvo; uga\u0161anje osvetlitve npr. Trgovine, ko ni obiskovalcev; Objekti za ogla\u0161evanje, naj bodo majhni in pravilno osvetljeni, saj lahko zagotovimo le to, da svetilke ne svetijo nad vodoravnico, kar je najve\u010dji problem panojev. Ve\u010dina znakov in reklamnih panojev sveti 50% nad vodoravnico.<\/p>\n\n\n\n

 Vsak pobegli \u017earek svetlobe je dodaten udarec po va\u0161i denarnici. Zato vas vabiva, da se skupaj potrudimo in s tem kon\u010damo prito\u017eevanje nad visokimi ra\u010duni. Razumimo, da so \u017eivljenja \u017eivali pomembna prav tako kakor \u017eivljenja ljudi. Moramo si zapomniti, da ta dejanja vodijo do svetlej\u0161e prihodnosti, ki pa ne rabi biti dobesedno svetla.<\/p>\n\n\n\n

ENGLISH:<\/p>\n\n\n\n

Do you also complain about electricity bills while still unnecessarily leaving the lights on? <\/p>\n\n\n\n

Unfortunately, by doing so, you are causing harm to yourself and others.<\/p>\n\n\n\n

Light pollution is the emission of light from man-made sources that increases the natural illumination of the environment. Experts estimate that in Europe, approximately 1 square kilometre is newly illuminated each day. Due to the careless use of man-made light, people are gradually heading towards a future where the night will be as bright as daylight. So, we might be able to read books at night without any additional lights. Ironically, this future is not bright, and we must take action to change it.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Addressing the problem begins by tackling the weakest link. In our case, it is the lighting of public structures such as churches, monuments, and billboards. Most of these structures are illuminated from below, with often 60% to 80% of the total light flux escaping past the facade into the sky and surroundings.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

This stray light disrupts the biorhythms of many animal species, including humans. While light attracts some animals, trapping them to wander around the light, it repels others, reducing their natural habitat.<\/p>\n\n\n\n

Light has the greatest impact on insects, triggering a chain reaction that also affects other animal species, such as bats, which depend on feeding on bugs. Insects use the moon as orientation since it is a source of light.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Light sources made by humans disrupt both the daily rhythm and the migrations of insects, affecting their feeding and reproduction. Insects see this as daylight, which in most cases leads to their death. The mass dying of insects and the illumination of public structures also directly impact bats.<\/p>\n\n\n\n

The illumination of public structures causes female bats to start hunting later than usual, missing the peak evening hours when there are the most insects. Poorly nourished ancestors also do not provide as good of a care for their offspring, resulting in slower growth and increased difficulty in survival.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Light also negatively affects the human rhythm and health. The circadian rhythm, also known as the day-night biological rhythm, is crucial for our well-being. Excessive man-made light during sleep disrupts the production of melatonin, which is known as the sleep hormone.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Melatonin acts as an antioxidant and anticarcinogen, influencing the quality of our sleep and well-being. Melatonin deficiency can lead to various diseases in the old age.<\/p>\n\n\n\n

CONCLUSION:<\/p>\n\n\n\n

We believe that reducing the unnecessary use of light is essential to preserve all animal species and decrease the appearance of diseases associated with artificial illumination. However, we also acknowledge the fear of a future with limited access to energy. Some of our proposed solutions include replacing white LED lights, because they emit blue light that disrupts melatonin production even with minimal exposure. We suggest replacing it with warm (yellow) colour-reflecting lights; turning off lighting in places like stores when not in use; ensuring that advertising objects are small and correctly illuminated, avoiding lights shining above the horizon, which is the main issue with billboards. Most signs and advertising panels emit 50% of light above it.<\/p>\n\n\n\n

Every stray ray of light is another hit to your wallet. However, we encourage everyone to put in the effort and end the complaining about high bills. We acknowledge that the animals\u2019 lives matter as much as the lives of human beings. We have to remember that these actions lead to a brighter future\u2014but it doesn\u2019t have to be bright in the literal sense of the word.<\/p>\n\n\n\n
