When the moon appears as a thin crescent in the sky during twilight, we can often observe that the rest of your disc also shines faintly. This phenomenon is called cinereal light and is due to the reflection of sunlight by the Earth, which in turn illuminates the lunar surface. Once reflected by the earth, the colors of the radiation, which appear as a rainbow in the image, change significantly.
Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon.
By observing cinematic light, astronomers can study the properties of Earth's reflected radiation as if it were an exoplanet and look for signs of life. The reflected radiation is also highly polarized and the study of this polarization, as well as the intensity of the different colors, allows testing of the presence of life very sensitively.
Earthshine is even more faint because the moon's "albedo" (a specific kind of reflectivity) is less than Earth's. Even though this dim light is only a reflection it can still illuminate some features of the moon. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon).
James William Arthur Taylor (born 6 January 1990) is a former English cricketer who played for Nottinghamshire County Cricket Club.A right handed batsman and occasional right-arm leg break bowler, Taylor made his debut in first-class cricket in 2008 for Leicestershire and made major impressions in his first county seasons. He is noted as being a fine fielder in the covers. He became the youngest Leicestershire one-day centurion and first-class double centurion. In 2009, Taylor also became the youngest player in Leicestershire's history to score 1,000 championship runs in a season.
So to me it looks like that into more of the future more people are born in Urban areas and in the Rural areas it looks like it will slowly go down till there is little to none left.
