Since 2010, Joye Braun, a member of the Cheyenne River Sioux tribe in Eagle Butte, South Dakota, has fought the construction of oil and gas pipelines in her region, working to protect sacred places where her forebears hunted and fished and lived and died.Today, Braun is opposing a huge new pipeline that would transport carbon dioxide across five Midwestern states — Iowa, Minnesota, Nebraska, and North and South Dakota.The project will sprawl 2,000 miles across the five states, capturing carbon dioxide before it is released into the air by 32 producers of ethanol, a biofuel made from fermented corn.Pressurized and liquified, the carbon dioxide will flow through the buried pipeline to storage reservoirs several thousand feet underground at various locations in western North Dakota, the company says.Asked about the vote in Emmons County, a Summit spokesman said in a statement: “Opponents of modern agriculture and traditional energy have mobilized and are activating landowners against the project using misinformation."
