The campaign to oppose the construction of the Dakota Access pipeline (DAPL) continues to gain steam with Leonardo DiCaprio and actors from the upcoming Justice League film joining the cause. Dakota Access-a subsidiary of Texas-based Energy Transfer Partners LP-has proposed a $3.7 billion, 1,168-mile pipeline that will transfer up to 570,00 barrels of crude oil per day from the North Dakota Bakken region through South Dakota and Iowa into Illinois.
