“In order for the light to shine so brightly the darkness must be present.” -Francis Bacon
Recently, a team of international researchers has assembled the most comprehensive, up to date study on light pollution on Earth ever, including a full-Earth map of dark sky conditions or lack thereof. Its findings were disheartening but unsurprising, including the fact that 80% of Americans and 60% of Europeans cannot see the Milky Way.
Although this may have detrimental effects to plants and animals, the largest negative may be humanity’s disconnect from the night sky, and the Universe beyond our world as a result. If you’re interested, it’s not difficult to find a dark sky location within two hours of your location, pretty much independent of where you are.
