Talking Hawk... pointed to the river's tea-colored water as proof that the overwhelming amount of pollution humans have produced has caused changes around the globe...

I'd say that the 'tea-colored' water was proof of Talking Hawk's overwhelming load of Bull 'Pucky' except for the fact that the river water was the same color when I was a kid in the 1960s paddling a canoe in the Boy Scouts down the rivers of central Florida. It's called called tannin and it's a naturally occuring chemical in tree roots and leaves that causes river water to turn brown.

The irony is that native American indians are among the worst polluters, hands down, of any group I've observed.

I have travelled across numerous reservations across the western U.S.; the filth and trash that they emit just makes me plain depressed.

Fun Fact: Tannin is also present in tea-leaves
