Species Richness Quotes (1 quote)
The most commonly used measure of biodiversity is species richness, which simply means the number of species in one place. But that measure alone does not tell us how healthy an ecosystem is. For example, think of a pristine coral reef and an overfished coral reef. The pristine reef might have dozens of gray reef sharks, whereas the overfished reef could have just one shark left.

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
