The Carbon Cycle Author:Leonard Ridzon The Carbon Cycle defines the role of carbon in the soil digestion process. Priceless is Ridzon?s insight into the soil carbon function in handling toxicity. The point of this volume and its earlier companion, The Carbon Connection, is that the carbon frame has to come first, although it is dependent on the right ingredients, namely a gas, a liqu... more »id and energy. This energy must pump moisture from the soil and lift it against gravity into the sky at least as high as plants grow. If oxygen would fall below 15% in the atmosphere, the fires would go out and we would all suffocate. If oxygen would climb to over 25%, the world would explode. The temperature of planet Earth is regulated within this narrow range. Life does all of this, governed by carbon. In Ridzon's words "...death is life without carbon."« less
