diplomsko delo

Abstract

Popolna tema nam daje občutek utesnjenosti, zato potrebujemo umetno svetlobo. Z razsipnim ravnanjem z razsvetljavo pa smo presegli meje njene koristne uporabe, ob tem pokrajini jemljemo njeno identiteto. Svetlobno onesnaževanje poveča naravno osvetljenost okolja in je vidno kot žarjenje neba v smeri svetlobnih virov. Kljub opozorilom okoljevarstvenikov so ljudje večinoma brezbrižni, ko slišijo za termin svetlobno onesnaženje, predvsem ko je govor o škodljivem vplivu umetne svetlobe na nočna astronomska opazovanja, na poseganje v bioritem flore in favne, na povečane izpuste toplogrednih plinov, ki povečujejo učinek toplogrednih plinov, ter na spreminjanje kulturne pokrajine, toda samo dokler ne slišijo posledic, ki se navezujejo na vsakega posameznika: kako po nepotrebnem plačujemo veliko višje položnice za porabo elektrike, kot bi lahko; kako umetna svetloba vpliva na naše zdravje, da lahko povzroči nastanek raka; kako je na cestišču zaradi nepravilne razsvetljave povečano bleščanje, ki moti naš vid, ter ne nazadnje, kako so naši otroci morda že generacija, ki ne bo mogla več uživati v pristnem nočnem nebu. Ko začnemo o problemu širše razmišljati, se zavemo resnosti le-tega. S kakovostno javno razsvetljavo in racionalno postavitvijo lahko dosežemo neverjetne rezultate. Nezasenčene in delno zasenčene svetilke bi morali odpisati in jih zamenjati z ekološkimi, pravilno nameščenimi. Take svetijo na mesto, kjer svetlobo potrebujemo, ne pa v atmosfero, kjer je nekoristna. Ponekod se lahko razsvetljava v drugi polovici noči ugasne, saj je takrat večina ljudi neaktivnih. S pravilnimi ukrepi bi pripomogli k manjši degradaciji okolja, v katerem živimo. Proučevanje svetlobne onesnaženosti je podprto z obsežnim terenskim delom na enem izmed kanarskih otokov - na Tenerifu. Delo zajema zbiranje gradiva v obdobju trimesečnega bivanja na otoku z meritvami in zajemanjem fotografij sija neba in viri osvetljevanja, kot primeri slabe prakse.

Secondary title:	Light pollution in Tenerife
Secondary abstract:	In complete darkness we feel a sense of anxiety that is why we need artificial light. With the wasteful use of lightening we have exceeded its beneficial uses; in addition we have taken the landscape's identity away. Light pollution increases natural light of the environment and is seen as the glowing of the sky in the direction of the light source. Despite warnings from environmentalist mostly people are indifferent when they hear the term light pollution. Above all when speaking about the harmful effects of artificial light at astronomical observations at night, the interference on the biorhythm of flora and fauna, increased greenhouse gases emissions increasing the effect of greenhouse gases and changing cultural landscape. However, until they hear the consequences which are related to each individual. How we are unnecessarily paying much higher bills for electricity consumption as we could, how artificial light affects our health, it can cause cancer, how due to improper lighting on the road the glare is increased, which disturbs our sight and finally how our children are perhaps the next generation that will no longer be able to enjoy an authentic night sky. When we start to think about the problem more broadly, we are aware of the seriousness of it. With the quality of street lighting and the rational layout we can achieve amazing results. Those that are not shaded and those that are partially shaded must be given to the write off and be replaced with the eco lamps which are installed correctly. They shine on the place where light is needed rather than into the atmosphere where it is useless. In some places lighting in the second half of the night may be turned off, because at that time most people are inactive. With the right measures we could help to smaller degradation of the environment, where we live. The study of light pollution is supported by extensive fieldwork on one of the Canary Islands - Tenerife. The thesis contains collecting of materials for a period of three month's stay on the island with the measurements and the photographs of the glows of the sky and lighting sources as examples of bad practice.
