There is no other natural resource on the planet that has contributed so much to both the health and beauty of this Earth and to the development of the human race, than wood and trees.
From the caveman and his club, to the explorer with his ship and the traveller with his wheel, not to mention heat, shelter and food. Homo sapiens could not have developed into the sophisticated society we know today without wood and trees.
Worldwide there are over 600 species of what are sometimes called softwoods or coniferous (pine, spruce etc) and over 70,000 species of hardwoods or deciduous (oak, mahogany etc).
