The state of Alaska says it will sue the U.S. Fish and Wildlife Service over protections recently put in place to help polar bears faced with the effects of climate change.
Polar bears are listed as threatened under the Endangered Species Act, and as such more than 187,000 square miles of critical habitat in the Arctic has been designated to help the species recover.
The state says the critical habitat includes areas where there is little or no evidence that the areas are crucial to polar bear conservation.
The state on Tuesday put the federal agency on notice that it intends to sue unless the critical habitat designation is changed. If no action is taken in the next 60 days, the state will file a lawsuit.
