The Idle No More movement, asserting Indigenous rights against Canadian Government attempts to destroy them, has targeted, among other things, mining company De Beers, controlled by London-based Anglo American. Indigenous protests have also taken place in the USA, including against Rio Tinto‘s Kennecott subsidiary in Michigan. The movement also opposes destructive tar sands ‘development’ by, among others, BP and Shell.
