Today is a global day of action against the $3.8 billion Dakota Access pipeline, which has faced months of opposition from the Standing Rock Sioux Tribe, as well as members of hundreds of other tribes across the U.S. and Canada. As many as 80 protests are expected to take place today in major U.S. cities, including New Orleans, Denver, Anchorage and Honolulu, as well as in Britain, Portugal, Japan and other countries.
