Most of the electricity in my area of the USA is produced by hydroelectric dams that harness the power of gravity to generate electricity without pollution. The native tribes in my area have been lobbying for decades to have these dams dismantled, to save the environment they claim. Native Americans are anti-civilization. They're still butt hurt that civilization conquered their stone age ancestors who hadn't even invented the wheel yet. They believe that harnessing nature in any way to make human life better is evil. Even though today they wear our clothes, eat our food, use our technology, and generally benefit from everything that civilization has built. Hypocrites.
