The actress joined a Washington, D.C., rally asking the president to ban the natural gas drilling method on federal lands.

Actress and environmental activist Daryl Hannah made known her displeasure with President Barack Obama's environmental policies at a press conference and rally Thursday, August 22, in Washington, D.C.

Hannah and the coalition Americans Against Fracking asked Obama and the Bureau of Land Management to ban fracking on public lands. They say they delivered 625,000 signatures demanding stricter regulations at the rally.

"We as the public, as human beings, need to stand up for our life support system," Hannah tells The Hollywood Reporter. She says she was pleased with the turnout at Washington's Lafayette Square, calling the crowd "respectful but firm."

Hannah and the other protesters are unhappy with the Bureau of Land Management's recent proposed regulations on fracking, which environmental activists have criticized as being too weak. The government closes a public comment period for the proposed regulations Friday, August 23, which is why Hannah says the rally took place Thursday.

"They have a mandate to look after the health and biodiversity of these public lands for the citizenry," she says.

Hannah, known for her work in the Kill Bill films, is one of several Hollywood stars who have adopted the anti-fracking banner. Matt Damon, Mark Ruffalo, John Krasinski and Zoe Saldana also have spoken out against it.

Hannah has a long history of environmental activism and has been arrested several times at protests. Most recently, she was taken into custody in February in front of the White House protesting the Keystone XL pipeline.
