Filtering Fantasy Air

WHEN "I" BUILT MY HOUSE, it was located, and still is, between large trees.The house faces south, and the trees are close to the house, at both the east and west ends, and belong to my neighbors. During the summer they block the sun for all but a couple of hours each day. During the winter the sun, low in the south, comes streaming beautifully into the house through leafless trees in my front yard. I live in a small forest which I planted twenty years ago. I seldom need to use air conditioning, even when the temperature is above nintey. On summer nights I open all the windows, and use a window fan to suck in the fresh, night air. By morning, I can begin the day with a nice cool house filled with fresh air, and keep it that way by closing the windows during daylight hours. I lie in bed at night, and I hear the gentle buzzing of the fan, and I feel the fresh clean night air flowing in through the window screens, and out through the window with the fan pointed outward. I'm a ventilation freak. Wherever I am,I want fresh air in the room, circulating in from outside. Nothng dismays me more than to walk into a room full of people and no ventilation, and to inhale the aroma of carbon dioxide and human breath. My imagination kicks in, and I imagine the window screens as air filters, filtering all the pollution, especially carbon, out of the air, and filling my house with the pure clean nitrogen oxygen mixture which we seldom actually get to inhale. Window screens, cleaning the air like trees, only faster. I wonder how much air goes through the house at night, how much of my imaginary newly cleaned air I am sending back out into the world every summer night. Enough to make a difference? What if the window fan ran twenty four seven, all year along? I'd freeze to death, for one thing. What if every house and building on Earth did the same thing, filtering tons (does air come in "tons?") of air through window screens whenever the weather allows? Suddenly I remember that in Germany, for instance, people don't have window screens. I learned this from a ninety year old lady who was born and raised in Germany, remembers Hitler, and came to the United States with her American serviceman husband the year I was born, 1955. I'm just guessing that if the carbon removal and sequestration window screen technology of my fantasy ever actually manifests, that the Germans will suddenly fall in love with window screens, and install them in all buildings. The Germans are like that. When RFK, (the sane father, not the insane son), was murdered, his brother,Ted, said at his funeral: "some men see things the way they are, and say "why"? He saw things that never were, and said "why not?" Perhaps we could all benefit from doing more of that. Or, as John Lennon said "Imagine". Or, as Einstein said "Imagination is more important than knowledge." Einstein also said that as long as there are people on Earth, there will be violence war. I don't agree with this, even though every piece of available evidence clearly indicates that it is perfectly true. I refuse to believe it, because I refuse to be realisitc, if reality is that unsavory. I prefer to live in my imaginary world in which some fine day the air will be clean, there will be no more war or violence of any sort, and our descendants will not hate and curse us for the world we left to them.
