It's official. Environmental groups are disenchanted enough with the Obama administration that they've decided to hit it with the same tactic they used for Bush, a tactic that the environmental movement has relied on since time immemorial to get done what needs to be done: suing the crap out of the government.

Today, a suite of environmental groups that includes NRDC, EDF and Earthjustice revived a 2008 lawsuit they'd first brought against the Bush administration. Its aim is to keep people from breathing nasty, dirty, health-threatening air by forcing the government to tighten smog standards.

The Obama administration was going to do that on its own; now it's not planning to. No one likes improving the environment via legal brief. But the Obama administration hasn't left many other options open.
