Leonardo DiCaprio is among several high-profile actors who are protesting a proposed oil pipeline on social media.

According to EcoWatch, DiCaprio shared images on Instagram and Twitter voicing support for efforts being led by members of the Standing Rock Sioux Tribe to oppose the Dakota Access Pipeline.

DiCaprio also shared a link to a petition that is urging the U.S. Army Corps of Engineers to stop the pipeline from being constructed.

Jason Momoa, who will star as Aquaman in the upcoming “Justice League” film, also took to social media to protest the pipeline’s proposed route.

The pipeline would travel about a mile away from the Standing Rock Reservation, EcoWatch said.

According to Dakota Access, the project is a new 1,168-mile, 30-inch diameter pipeline that will connect Bakken and Three Forks production areas in North Dakota to Patoka, Illinois.

The pipeline will be able to transport about 450,000 barrels per day with a capacity as high as 570,000 barrels per day or more, accounting for about half of Bakken current daily crude oil production.

The pipeline will allow shippers to access multiple markets, including Midwest and East Coast markets as well as the Gulf Coast via the Nederland, Texas crude oil terminal facility of Sunoco Logistics Partners.

The project is expected to cost $3.7 billion and is anticipated to create between 8,000 to 12,000 local jobs during construction.

The pipeline is operated by Dakota Access, LLC, a subsidiary of Energy Transfer Crude Oil Company, and could be in service by the fourth quarter of 2016, depending on regulatory approvals.

The Army Corps of Engineers is studying the project and will issue a decision on whether construction can move forward within the next several months.
