Marker Quotes (1 quote)
In the Anthropocene, the time of humans[,] … rocks … are forming today. Not only will they contain fewer species than the rocks that preceded them but they will contain markers that are completely new—fragments of plastic, plutonium from nuclear activity, and a worldwide distribution of the bones of domesticated chickens.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) -- Carl Sagan
