Why its good to burn wood

Riding the Carbon Cycle: The carbon cycle is nature's way of moving carbon around to support life on earth. Carbon dioxide is the most common vehicle for carbon, where the carbon molecules are bound to oxygen. Plant photosynthesis breaks the carbon dioxide in two, keeping the carbon to form the carbohydrates that make up the plant, and putting the oxygen into the air.

When the plant dies or is burned, it gives its carbon back to the air, which is then reabsorbed by other plants. Fossil fuels, on the other hand, are made of plants that grew millions of years ago. The carbon they absorbed then is released now when the fossil fuels are burned. There are no extra plants to absorb that carbon, so the cycle becomes out of balance. There are two different carbon cycles in operation now: the natural one between plants and the air, which is in balance, and the human-made cycle where carbon is pulled from the earth and thrust into the atmosphere.
