Urban Light Pollution

Recent studies have shown that urban light pollution not only blocks our view of the stars to an extent at night, but some nocturnal animals are having trouble navigating their celestial compasses as well.....I found it interesting that animals could use the stars for navigation. Here is the whole article: http://www.sciencedaily.com/releases/2011/10/111027112513.htm

I think this article is extremely interesting. I am still a little bit confused about what urban light pollution is though. Also another thing that intrigued me was how studies have discovered that some nocturnal animals are having difficulties in navigating their celestial compasses. I wonder how scientists go about measuring that.

It really is unfortunate that light pollution has affected us in so many ways. Especially because a ton of the lights causing the pollution aren't even necessary.

I find it really interesting that stars played such a role in animals' lives. And a shame that light pollution is harming that role. I've always disliked light pollution because I would much rather see the stars at night than my neighbor's front porch, or the convenience store across the street. It's something that I've always wanted to escape actually, since I found most sources of light pollution to be completely unnecessary.

How do scientists know that animals are having trouble navigating?

Growing up in Los Angeles I connect a lot with this article. It is very hard to see any stars at night unless leaving the area. To answer your question about how scientists know that animals are having trouble navigating, one major way birds migrate is using the stars. Without being able to see them obviously, migration would be very hard.

Light pollution is an unfortunate side affect of urban settings. It was bad enough when light pollution was affecting astronomical observation and was causing energy waste, but now light pollution is affecting the ecosystem and navigation of animals. However, it will be difficult for governments to regulate light pollution because it is difficult to measure on an individual basis.
