Ben Affleck recently united with his Justice League crew for a new video opposing the construction of the Dakota Access Pipeline.

The superhero squad, which is currently filming the upcoming DC Comics team up flick in London, joined together to show their support for the Standing Rock Sioux Tribe and others who are demonstrating against the $3.8 billion oil pipeline. Opponents say that the planned construction under the Missouri River could have a disastrous effect on several of the tribe’s sacred sites as well as their reservation’s supply of drinking water.

In a video posted by Change.org, Affleck, along with his Justice League co-stars Ray Fisher, Gal Gadot, Jason Momoa, and Ezra Miller, urged their fans to take a stand by supporting the cause Rezpect Our Water in its fight against the pipeline.

“As a gang of Earth defenders, we want to send a big shoutout to the Oceti Sakowin and those opposing the Dakota Access Pipeline,” Miller says in the video on behalf of the group. “To get involved with this movement, go to SacredStoneCamp.org.”

The debate over the pipeline took a violent turn over the weekend when private security officers from Energy Transfer Partners, the parent company of Dakota Access, attacked protesters with dogs and pepper spray. Thousands of demonstrators from more than 100 tribes came together at a construction site in North Dakota to protest against the project, which would funnel 500,000 barrels of crude oil per day to Illinois if the pipeline is completed.

Green Party presidential candidate and Lexington resident Jill Stein, who was also at the protest, is facing charges stemming from the demonstration after she allegedly spray-painted construction equipment, according to the Associated Press.
