ONE--I'm a septagenarian, and probably fairly close to the curtain. A main aim of my life has always been to help in leaving this Earth as healthy as possible; it doesn't belong to me --or you---it belongs to the innocent kids [and animals--]and the yet unborn. TWO---As far as I can gauge, global warming is a fact.We may be entering a natural warming cycle---but there is NO doubt that human activity is exacerbating it. THREE--- NOBODY can state with any certainty that fossil fuel burning, deforestation, etc. is NOT causing accelerated warming. So it follows that those who persist in advocating the continued "march of progress" in the present manner are purely and simply gambling that they MIGHT be right---and using for chips the lives of children and the future of the Earth as a viable life-sustaining planet.
