Photographs Of Cities From Space Have Shown A Worrying Trend

A photograph of Washington DC tweeted from space by Scott Kelly, via Twitter.

LED street lamps are good news for the environment, known to provide more light with a greater efficiency, so it’s no surprise much of the world’s cities are switching over to them.

In many respects, we shouldn’t be complaining about this. However, scientists at the Complutense University of Madrid in Spain were documenting photographs of cities taken from space and noticed a worrying side effect of this switch over: light pollution.

A recent study showed how one-third of Earth's human inhabitants can’t see the Milky Way in the night sky due to light pollution, but this isn’t the only concern. This video from Tech Insider shows some of the worrying effects that could be brought about if current trends of light pollution continue.
