Are you guys really sure of what you are supporting?
I'm afraid I won't be supporting this issue, as presented by the parties involved as a result of a little research into the organization and it's backers.
One glaring instance is the involvement of Mr. Richard Pombo, former member of the House of Representatives.
The following is copied and pasted from the Wikipedia article on this individual...
Pombo has proposed legislation to sell roughly a quarter of the land managed by the National Park Service. In November 2005, Pombo and Jim Gibbons (R-NV) co-authored an amendment to the Federal Budget Reconciliation Bill easing restrictions of sale of federal lands to mining companies. This amendment was opposed by environmentalists, anti-growth advocates, and even some Republican Senators concerned about the measure's effects on hunting and fishing. The amendment narrowly passed the House, but was defeated in the Senate. The legislation was later described by his chief of staff as a "bureaucratic exercise" designed to evaluate the costs of not drilling in the Arctic National Wildlife Refuge (ANWR).
Pombo has likewise pushed for oil drilling in the ANWR, despite concerns about the fragile ecosystem and opposition from moderate Republicans. .
In September 2005, Pombo helped rewrite the 1973 Endangered Species Act. The proposed revision "was widely denounced by environmentalists as a disturbing retreat from habitat protection and a paperwork nightmare for agencies seeking to revive the 1,268 threatened and endangered plants and animals in the country, 186 of which are in California."
By March 2006, Environmental Science & Technology reported that Pombo was coordinating efforts with Pac/West Communications to weaken the Endangered Species Act (ESA). Pac/West has created the Save Our Species Alliance, an anti-environmental front group that is campaigning for Pombo's bill to change the ESA.
The League of Conservation Voters, a nonpartisan PAC, assigned Pombo a lifetime average rating of 7 on a scale of 0 to 100. In 2005, he scored a 6. Subsequently, the organization has also named Pombo as one of the "Dirty Dozen" in 2006 . LCV released an ad on October 31, 2006, citing Pombo's acceptance of $120,000 from oil companies and his ties to indicted lobbyist Jack Abramoff .
For his anti-environment views, the magazine Rolling Stone ranked him one of the worst congressmen and called him "Enemy of the Earth" .
As the chairman of the House Resources Committee, Rep. Pombo blocked legislation that would have created the Wild Sky Wilderness area in Washington state, despite broad support for the bill.

His involvement in the organization that sponsors the petition is documented on their website...
You may well save public land from being classified as wilderness, only to see it sold for comercial devlopment in the future. Not a good tradeoff in my humble opinion.
