From NRDC:

Just before leaving office, the Bush administration issued sweeping changes to the Endangered Species Act to weaken protections for imperiled wildlife, including polar bears, wolves and whales. These changes decrease scientific review for activities that could harm threatened and endangered species and prohibit the government from considering the impact of global warming pollution on polar bears and other wildlife.

Interior Secretary Salazar now has the opportunity to help reverse these destructive changes. In March President Obama signed a spending bill that allows Secretary Salazar to overturn President Bush's last-minute changes to the Endangered Species Act regulations as well as a separate rule that weakens Endangered Species Act protections for polar bears. But the Obama administration must act by May 10th, and opponents of the Endangered Species Act are working hard to convince Secretary Salazar that he should not withdraw these rules.

What to do:
Send a message right away urging Secretary Salazar to withdraw the Bush administration's last-minute Endangered Species Act regulations and polar bear rule under the authority granted by President Obama and Congress.

From Defenders of Wildlife:

U.S. Interior Secretary Ken Salazar and Commerce Secretary Gary Locke have little more than one week to set right one of the Bush/Cheney administration’s most disastrous decisions on wildlife -- and we need your help to ensure that they do the right thing and restore key protections for polar bears, wolves and other imperiled wildlife.

Please send Interior Secretary Salazar and Commerce Secretary Gary Locke a message right now urging them to reverse the Bush/Cheney administration’s last-minute assault on Endangered Species Act protections for polar bears, wolves and other imperiled wildlife.

Before leaving office, the Bush administration rammed through regulatory changes to the Endangered Species Act that threaten efforts to save polar bears, wolves, manatees and more than 1,300 other species from extinction.

If left in place, these changes will...
Prevent the Endangered Species Act from protecting our vanishing polar bears from global warming, which would effectively allow America's threatened polar bears to drown in a sea of inaction; and
Let federal agencies in charge of building highways, dams and other projects decide whether those projects might drive rare plants and animals toward extinction, without ever checking with the expert biologists in the U.S. Fish and Wildlife Service and National Marine Fisheries Service.

Defenders of Wildlife -- and caring wildlife supporters like you -- fought hard in Congress for legislation that gives Secretaries Salazar and Locke the authority to overturn these rules. Now it’s up to Secretaries Salazar and Locke to use this hard-fought authority before it expires on May 9th.

Only 12 days remain to reverse the Bush/Cheney assault on Endangered Species Act protections for our wildlife. Please send your message right now!

More than 200,000 comments opposing the changes were submitted to the Interior Department in the 60 days that the Bush/Cheney administration allowed for the public to respond to its changes. And newspapers across the country have editorialized overwhelmingly against the Bush/Cheney administration’s gutting of Endangered Species Act protections.

Nonetheless, these regulations are now in place, and each day they remain in effect our polar bears and other vulnerable species are being placed at greater risk of extinction.

The good news is that a stroke of the pen by Secretary Salazar and Secretary Locke can restore Endangered Species Act protections for the polar bear and other endangered wildlife. The bad news is that neither secretary has taken action yet.

Use your voice to restore protections for our vulnerable wildlife. Encourage Secretaries Salazar and Locke to use the power that Congress gave them to protect the lives of our imperiled wildlife.

UPDATE:

I've added an additional petition to Secretary Salazar and Secretary Locke regarding this issue.

From CREDO:

Over the course of eight years, the Bush administration made a number of savage changes to environmental regulations, including those that protect endangered species.

Some of the worst cuts came in the twilight of the administration, as Bush officials rammed through midnight regulations that decimated protections for over 1,300 species — including polar bears, wolves and manatees.

For example, one regulation allows federal agencies to oversee the construction of new roads and highways without ever checking with scientific experts to see if such projects would harm endangered species. Regulations like these are reckless for our environment, and they must be overturned.

The good news is that Congress has empowered Interior Secretary Ken Salazar and Commerce Secretary Gary Locke to overturn these insidious regulations — but time is running out: They only have until May 9.

Click here to tell Secretary Salazar and Secretary Locke to overturn every last Bush regulation that erodes protections for endangered species.

Thank you for working to build a better world​
