The Japanese have been producing wood for 700 years without cutting down trees. In the 14th century, the extraordinary daisugi technique was born in Japan. Indeed, the daisugi provide that these trees will be planted for future generations and not be cut down but pruned as if they were giant bonsai trees; by applying this technique to cedars, the wood that can be obtained is uniform, straight and without knots, practically perfect for construction. #interestingness
