Letter: The more the better
28 May 2007
Sir - To discuss species diversity and taxonomy in the context of monetary inflation is a bit like watching a bank burn and observing that at least the remaining currency is gaining value ("Hail Linnaeus" May 19th).
Except for one thing: when a species goes extinct, we cannot just print another. Moreover, even if one accepts your analogy, it takes radical inflation for people to stop caring about the conservation of currency. As the value of money declines slightly year to year, people do not typically respond by throwing it away. Your examples of polar bears and raccoons in the Bahamas show that species recognition counts in a similar manner. Simply, the public values species more than other categories of diversity.
I like to dream of a world so full of diversity that the death of another species would be no great loss, or in which the difference between geographic variant and species would be less fateful. But it is just that, a dream. As it is, we are contributing to the greatest series of extinctions in the last 65m years, and likely condemning our closest relatives in the process. Our limited financial history provides no analogue for that.
