e are a lot of things out there in the world that are free." but are they really is the questions?
             Can you believe that Melville Dewey once said, "free as air, free as water, free as knowledge?" Free as knowledge? Let's get real, this is the modern world --- air and water no longer come cheap! Hey, you want breathable air, you better pay your air conditioner's power-bill. Free as water? If you've got sense you buy the bottled variety or pay for an ionic filter on your tap. And free as knowledge?

The thousands of dollars that are going into keeping the air clean due to the years and years of pollutants that mankind has been pumping into the it. That certainly is not free.
             We breath in this compound composed of oxygen, nitrogen, carbon dioxide and other insignificant gases and never in our minds does the question arise about the worth of this indispensable compound. If it wasn't for the four-eyed chemists in their white lab coats concocting new methods of cleaning the air in order to make it "breathable". Where would we be? Probably in the world filled with dust, radiation and skyrocketing amounts of carbon dioxide. All this valuable research and data doesn't come cheap. Every time you get your paycheck and you notice a couple of dollars missing and don't really think anything of it. Think about it. Air is not free. It does have an economic value even if it is "hidden." Once upon a time we did actual have "free...
