"An Alaska petroleum industry trade group has sued the federal government over its designation of 187,157 square miles as polar bear critical habitat, claiming it covers too much territory and could cost tens of millions or more in economic effects.
The Alaska Oil and Gas Association sued Tuesday in Anchorage.
"This is an area larger that 48 of the 50 states, exceeding the size of the State of California by nearly 25,000 square miles," association attorneys said in the lawsuit.
The designation is unprecedented — the largest area set aside in the history of the Endangered Species Act — and was done for an animal that is abundant, with 20,000 to 25,000 animals in 19 subpopulations, according to the group."
