Nerd Note: Thanks to fungi and other wood-eating organisms, carbon is recycled back into the biosphere rather than accumulating as piles of wood and cellulose and eventually being buried and turned in to coal as happened during the Carboniferous Period approximately 360 to 300 million years ago. At the beginning of that period, woody plants had come into existence, and it is believed that it took nearly 60 million years for fungi and other cellulose-degrading organisms to appear. For better or worse, most of the coal that has been used came from woody plants that piled up during that period for want of something to consume their corpses.
