The federal Endangered Species Act seems to make everybody unhappy these days. Extractive industries don't like the way it changes the way they do business (think logging and the spotted owl).
And environmental groups are frequently frustrated by the federal government's slow moves to protect sensitive species.
Take the wolverine, for example. The federal Fish & Wildlife Service withdrew its proposal to list the wolverine, despite its small population numbers. Now Cascadia Wildlands and other groups are threatening to sue.
