I have friends involved in these issues and actions, so if you can share this far and wide I would appreciate it! Some of the most pressing issues facing Native nations globally are these same issues of imposed environmental destruction that both causes a host of problems of its own such as pollution and illness but also significantly highlights the ongoing violation of these nations inherent sovereignty. No matter what legal fictions nations like Canada and the US come up with (like the US "domestic dependent nations" nonsense) the fact is Native nations ARE sovereign for the same reasons all nations are sovereign and NO ONE can grant that or take it away, at least not legally.
These environmental issues also affect non-Native people and the entire Earth in the case of global warming increased by the emission of the carbon from some of these projects, so these are really issues for everyone but at the moment all over the world Native peoples are facing them so directly and with such dire consequences (including mass murder in some cases, mass illness such as the cancers at four corners, and loss of homes and ancestral lands to submersion from dam projects like James Bay and Belo Monte) If you care about the Earth, Native people, or balance overall, these are very valid areas to focus your energy, time, actions and prayers as resolving these problems will produce wide ripples of good and blessings throughout our world.
