Yesterday, after a period of long delay, the Department of the Interior announced it would list the polar bear as a "threatened" species under the Endangered Species Act. Designating a species as threatened is not as serious as calling it endangered, but it still affords the species federal protections and special considerations.

The debate over whether to list the polar bear has been a hot button issue, because the main threat to the species is global climate change which is affecting the ice cover and sea conditions the bear needs to subsist.

Interior Secretary Dirk Kempthorne said that the decision to list the polar bear under the Act does not permit the federal government to regulate greenhouse gas emissions. "Protecting the polar bear under the Endangered Species Act is a major step forward, but the Bush Administration has proposed using loopholes in the law to allow the greatest threat to the polar bear — global warming pollution — to continue unabated," said Andrew Wetzler, Director of the Endangered Species Project at the Natural Resources Defense Council (NRDC).

Although Kempthorne is passing the buck on climate change, that doesn't mean the decision is a hollow one. Climate change is not the only threat to the polar bear. Man's physical intrusion into polar bear habitats can add unnecessary peril to a sensitive situation; industrial activities can disrupt any species' lifestyle.

In fact, the reason the Interior Department delayed the decision to deem the polar bear as threatened was because it needed to hurriedly approve permits for oil and gas extraction in parts of Alaska where the polar bear lives. The department was legally required to make its decision in January but stalled while its division in charge of minerals extraction doled out permits to big polluters. Environmentalists sued, and a court ordered Interior to make the decision by May 15.

Because of the listing decision, future actions that benefit special interests at the polar bear's expense will not be so easy. According to NRDC, "Listing the polar bear guarantees federal agencies will be obligated to ensure that any action they authorize, fund, or carry out will not jeopardize the polar bears' continued existence or adversely modify their critical habitat, and the U.S. Fish and Wildlife Service will be required to prepare a recovery plan for the polar bear, specifying measures necessary for its protection." That's good news for the polar bear.

The head administrator for EPA's Midwest Region, Mary Gade, resigned last week amid a political firestorm. Aides to EPA Administrator Stephen Johnson "told her to quit or be fired by June 1," according to the Chicago Tribune.

Gade claims she was forced out because she was trying to make Dow Chemical clean-up soil and sediment contaminated with dioxin, a highly toxic chemical and known carcinogen, in Saginaw Bay and Lake Huron. Dow has been dragging its feet on efforts to clean up the chemical which is emitted by its Midland, MI plant. Gade ordered Dow to begin dredging last year "when it was revealed that dioxin levels along a park in Saginaw were 1.6 million parts per trillion, the highest amount ever found in the U.S," according to the Tribune.

Gade was a Bush appointee, and a former corporate attorney who "had represented big companies like Dow against environmental regulators." Senior EPA officials are staying tight-lipped about Gade's resignation, but she told the Tribune she is certain it is a result of her aggressive pursuit of Dow: "On Thursday, Gade said of her resignation: 'There's no question this is about Dow. I stand behind what I did and what my staff did. I'm proud of what we did.' "

Ultimately, it doesn't matter whether Dow was the reason Gade was fired. EPA brass could say they fired Gade for stealing paper clips, but the damage is done: EPA officials on the ground will think twice next time they are considering aggressively enforcing environmental regulations, for fear of losing their jobs.
