It began earlier this year in North Dakota when members of the Standing Rock, Rosebud and Lower Brule Lakota tribes blocked construction of the Dakota Access Pipeline, but the #NoDAPL movement has grown in force and picked up supporters in states across the nation.
Nearly 300 other tribal groups and celebrities such as Rosario Dawson, Susan Sarandon, Ben Affleck and Leonardo DiCaprio have joined the original tribes in their campaign to stop the pipeline.
Tuesday was the #NoDAPL National Day of Action. Organized protests were planned in cities across the country, all with the goal of halting the pipeline permanently. ThinkProgress reports that protests took place in cities from San Diego to New York, backed by environmental organizations such as the Sierra Club and Greenpeace.
The nation's capital was the scene of a large rally as protesters gathered across the street from the White House, participated in a Native American prayer ceremony and gave speeches on the danger the pipeline poses.
Sen. Bernie Sanders (I-Vt/.) attended the Washington rally Tuesday and said, "This pipeline must be stopped."
Sanders added that there should be a full environmental- and cultural-impact analysis done on the pipeline.
On Twitter the #NoDAPL, #StandWithStandingRock and #RezkpectOurWater hashtags are filled with tweets from celebrities, journalists and everyday citizens offering their support, prayers and solidarity to those going to battle over the pipeline.
On Wednesday activists took to the streets of Washington, D.C., again, this time shutting down two different branches of TD Bank. TD Securities, the bank's parent company, is contributing $365 million to the pipeline project.
Protesters arrived at the branch on 17th Street N.W., and several went inside to deliver a letter asking the bank to stop lending money that will be used to build the pipeline. After the letter was delivered, the bank locked its doors, prompting protesters to hang yellow crime-scene tape that read "Fresh Graves Keep Out" on the outside of the bank's doors.
The protesters said they won't give up. Their actions have gained the attention of various city governments.
ThinkProgress reports that the Seattle City Council voted unanimously to approve a resolution supporting the Standing Rock Sioux tribe, and several other cities, including Portland, Ore., and St. Louis, have done the same.
Until the pipeline is stopped altogether, the grassroots movement continues.
