My gut level feeling is that there is a substantial part of the American public who does not really respond to the notion of, "if we burn, you burn with us." I think most are christians, many evangelicals. And more republicans than not. The bottom line is; they don't care; and, I think, a part of the reasons they don't, are bound up within their worldview. Ist many are waiting for the end of the World anyway. It's a part of their religion. And secondly, of course, they are going to heaven when they die. In other words they have no connection with the Earth as themselves. They are just here in a dominator role for a short while, then off to heaven.
Contrast this with the Indigenous peoples worldview of Vnci Maka( grandmother Earth), and humans as Earth protectors. My strong guess is this same mix in different formats was at least a part of the equation in the destruction of Mars, Lemuria, Atlantis , and now, 'the age of Trump', as livable habitat for humans and most all the other critters
All of us who feel a strong connection to the Earth understand the significance of Standing Rock. Water is Life.
