I've been following Gail Zawacki's blog, Wit's End, for a couple of years now and it has very usefully introduced me to another of the quiet killers of the unfolding ecological catastrophe: tropospheric ozone pollution (check out her science links if you are interested in the peer reviewed research materials). Below is the introduction to her latest post: A Fine Frenzy - The Universal Dance of Delusion ... and the Paucity of Hope. Nice to see her work getting wider distribution too (e.g. at Desdemona Despair and Op Ed News).
"To the philosopher, the physician, the meteorologist and the chemist, there is perhaps no subject more attractive than that of ozone." ~ C.B Fox, 1873
There is a man who lives on the other side of my village (it is said) who one day, setting out for errands, inadvertently ran over his child as he backed out of the driveway. Ever since I heard this tragic tale, I have thought I can imagine the moment that, thunderstruck with horror and frozen in disbelief, he gazed upon that little mangled body. I think I know the ferocious dread that overcame him when first he realized that the car of which he was so proudly enamored - that quintessential symbol of success, the pinnacle of modern technology and shiny avatar of individual freedom - was the very same mighty instrument of folly that had literally crushed the one thing most important to him - his progeny, his future.
I suffer his tumultuous and inconsolable grief because that is how I greet every new day since abruptly I came to understand that the splendid, intricate, exquisitely entwined tapestry of life is unraveling. This realization rushed into my consciousness like a dark sinister flood by an odd circumstance. In the summer of 2008 I suddenly noticed an irrefutable signal - that trees, the essential foundation of so much biodiversity, are dying prematurely. It was a hot, dry August, and everywhere the leaves were drooping, limp and lifeless. My curiosity piqued, the more I looked, the more I found indisputable, incontrovertible symptoms of irreversible decay. It was only the beginning recognition of an ominous trend. Now, the mute indicators of deterioration are common - swathes of bare branches protrude above the canopy.
Possessing just a rudimentary knowledge of the timescales involved in evolution was enough for me to realize the formidable outcome that must result as trees die off, when myriad crashes reverberate throughout the biosphere. Eventually, a total collapse of the ecosystem will be inevitable. Initially I speculated that the reason trees manifest terminal afflictions could only be attributed to the changing climate - surely the sole influence extensive enough to instigate such a colossal catastrophe. And yet, the climactic mechanisms - precipitation and temperature - did not consistently correlate with the empirical evidence I found, which was puzzling. It turns out, as incredible as it may seem, that the primary reason all species of trees - old and young, coniferous and deciduous - are in precipitous decline is their exposure to pollution.
