Compare the night skies of the desolate mountains and a bustling city and there lies a marked difference. The city skies glow with an artificial light of their own whereas you can see a galaxy of stars embedded in the distant skies away from human settlement and “man-made” light.
Even biologists now are wondering whether those lights are making the world more dangerous for animals and insects – particularly nocturnal creatures that thrive in blackness. Though the research is scattered, individual biologists are beginning to shed some light on species that haven’t taken kindly to artificial daylight. While biologists hesitate to say artificial light is killing or even seriously harming night-loving creatures, many agree that it is at least having noticeable effects. Take moths, for example. Anyone who has ever flicked on an outdoor light on a summer’s evening knows it is an invitation to every moth in the neighborhood. They spiral around it, drawn by some force unknown.
Light pollution is not even in the slightest manner absurd. In fact, it is a grave matter often overlooked by the world in preference of climate change and global warming. It is true, that it may not have as catastrophic consequences as the latter; nevertheless it is imperative for the world to wake up to its disastrous consequences. One can imagine if we had a water sprinkler system that wasted much of its water by scattering water everywhere; onto the street, through our neighbour’s windows, and upwards to encourage evaporation, we’d not tolerate it for long. If together we wasted over a billion dollars a year this way, we’d declare it a national disaster and begin conservation measures and efficiency improvements immediately. We must build a greater awareness of the adverse effects of poor lighting and get on with the task of using only quality lighting.
The economics of the situation would tell any layman that the humongous amount of money saved from conserving “light” and monitoring its use and scatterings can actually help feed billions of the hungry across the globe and give aid to the diseased and the victims of other natural calamities!
