it is not natural

I found this article back in early February but did not get a chance to read it until now. The piece is entitled Exploring the Link Between Exposure to Nighttime Artificial Lights and Thyroid Cancer Risk and I found it on the Technology Networks web site.

While it was not designed to establish causality, it discussed an observational study which compared lighting in satellite imagery to registered cancer cases for over 460 000 Americans. It suggests that there is a higher chance of developing thyroid cancer for people exposed to higher levels of outdoor artificial light. Perhaps it is due to disruptions in the circadian sleep patterns.

Certainly bright and constant lighting at night is not natural. We need to do whatever we can to limit or reduce this.
