Most of my family lives in Oklahoma. My BIL is half Cherokee.
I live in Idaho where there are many as you put it "natives." Here the term is Native Americans, and, frankly I am not quite sure what climate change/environment has to do with Native Americans and cancer.
2 members of my family have died from cancer recently and 2 of my neighbors died from cancer. My best friend died from cancer and none of them were "native." They suffered just the same. I just found out today that a close friend of mine has terminal breast cancer and her only wish is to live long enough to see her son graduate from high school.
I am not quite getting your point...what does being a "native" have to do with climate change and the environment?
Never mind...I don't want to debate this with you...it's rather pointless.
