The Center for Biological Diversity (CBD) portrays itself as a pro-science, non-profit organization that simply wants to protect endangered species. In reality, it's largely a group of lawsuit-happy lawyers.

Scientists would like to have a list of all the species on Earth. That sounds like a relatively straightforward, purely academic exercise, but it really isn't. Unfortunately, one major reason is politics.

Classifying species is a notoriously sticky problem in biology.
