Biologists have created a way to
track endangered species that they say is
similar to the way we track financial markets.

The new system is nicknamed the Dow Jones Index of Biodiversity.
It’s put together by the International Union for Conservation of Nature and the
London Zoo.
Jonathan Baillie is with the zoo. He says the system helps keep track of which
species are doing well and which ones are close to extinction.
“So if you thought of a group of species like a company you can track what’s
happening to birds through time, what’s happening to mammals through time
what’s happening to amphibians through time – and we’re seeing amphibians
are crashing quite quickly, birds are going down but not as rapidly.”
Of course species can’t be tracked exactly like financial markets. The species
index gets updated every few years instead of every day.
Soon they’re hoping to track things like beetles, mushrooms, and lichens on the
index.
