Climate change, imho, is a smokescreen to deflect attention from the man-made chemicals we've unwittingly loosed upon our planet's ability to adapt to their accumulating presence in our entire biosphere. "Planet Ocean" and many other documentaries, have demonstrated that, which Dr. Blake's 1989 BBC production of "After the warming" warned the world about, which Ban Ki-Moon warned us about in the 2009 Copenhagen Climate Conference. Willful ignorance is bliss. There is absolutely nothing that has been invented, proven effective and scaled up to prevent the deaths of the less adaptable life forms on our planet. Contaminated, or cooked, when the microorganisms at the base of all our food chains can no longer adapt to the presence of those chemicals in their environment and food, global famine, mass migrations, pandemics, and conflicts become inevitable. How many species have become extinct in my lifetime, 73 years, I have no idea. None have evolved that are worth consuming, yet.
