When cutting wood pieces for a window sill project, I could not help but wonder the genius of plants. Dryed wood is composed at 96 % of only three elements: carbon (45 %), oxygen (45%) and hydrogen (6%). Trees harvest those atoms from the CO2 in the air and the H2O pumped by the roots.
Trees recombine air and water by the means of photosynthesis to produre cellulose and lignin, the building blocks of hardwood. Wood can last millenia and stand straight against the wind at more than 100 meters high in a single piece measuring only a few decimeters at its base.
No man-made machine can measure up with trees.
