From the Youtube description: The North Dakota Access Pipeline is a controversial pipeline meant to bring 570,000 barrels of oil through North Dakota, South Dakota, Iowa, and Illinois. It should generate approximately $10B in revenue every year. It crosses the Mississippi and Missouri rivers multiple time and is a source of contention. Water protectors have gathered from across the country from 280 tribes to amass 5,000 protesters. The protesters have been met with brute force by the state and private security firm GS4.
