This letter was inspiring.  Reading the comments here however is depressing.  I hope 90% of those comments are written by trolls.  It is generally the case. Otherwise, I think I'm just going to give up on humanity. Biology 101: we all need to breathe air and drink water to live - whether we are aboriginal people or not. The difference is: they know it and this is why they protect it; our civilization is so caught up in the everyday grinder, it has forgotten one important thing: if we don't survive as a species, all the rest (the economy, getting rich destroying the Earth, driving a big truck, getting a fat pay cheque from the oil/gas companies) is no longer a thing, because we are sick, we are starving, we are dead.  Why are you all starting a war against each other? It is totally ridiculous.  In the 70's they thought smoking cigarettes wasn't bad for people.  They drove and smoked with all the windows up with 3 kids on the back seat wearing no seat belts.  Get on with knowledge people
