Discovery Communications used to be known for their earth-friendly offerings. But they’ve just paid millions to Sarah Palin to host a “nature” show, despite her decidedly anti-environmental stance: She vocally advocates for habitat-destroying oil drilling, she denies global warming is a human-caused threat, and she spearheaded a brutal wolf-slaughter program as governor of Alaska.

It’s one thing if Fox News gives Sarah Palin a platform. But when Discovery Communications – home to the Discovery Channel, the "Planet Earth" series, the Science Channel, Animal Planet and Treehugger.com – gives a show to Sarah Palin, it undercuts everything the Discovery brand has come to represent.

Anti-environmentalism has no place in the Discovery Communications lineup. Demand that the company cancel "Sarah Palin's Alaska" before it airs.

The former partial-term Alaska governor is reportedly getting paid $1.2 million per episode to host a television series called "Sarah Palin's Alaska," to be broadcast on TLC, one of Discovery Communications' channels. And if Palin runs for president in 2012, a show that provides her the opportunity to greenwash her environmental record on a mainstream, eco-friendly channel is downright dangerous.

Here’s what Sarah Palin’s real Alaska is:

-- She accelerated Alaska's cruel aerial wolf-hunting program while in office, introducing a $150 bounty for each slaughtered wolf's forelimb.

--- She made a personal appeal to Alaska voters to oppose a ballot measure that would have stopped the immense Pebble Mine operation from dumping cyanide and mining waste into streams that make their way to Bristol Bay, home to the largest sockeye salmon fishery in the world.

-- When President Bush finally agreed to list the polar bear as a threatened species in 2008 because of global warming's effects on its habitat, the governor sued to challenge the listing.

-- Armed with her "Drill, Baby, Drill" catchphrase, Palin called for opening the Arctic National Wildlife Refuge and the Cook Inlet to oil and gas drilling.

With such a disastrous environmental track record, how could Sarah Palin get a nature show on an eco-conscious media platform like Discovery? The answer may lie in Discovery's COO, Peter Liguori, who joined Discovery in December after a previous stint at Palin's other TV home: Fox Broadcast Co.

We can't let an anti-environment extremist like Sarah Palin take over Discovery and spread her "drill here, drill now" message on a science and environment network.

Speak out now and demand that Discovery pull Sarah Palin's show before it airs.
