Many people will concern about deforestation caused by building plyscrapers, the tallest buildings made by woods.
But, it's not the case in Japan, where tons of cedar trees were planted after World War 2 to supply a lot of woods for construction. That's because cedar trees can grow more rapidly than conventional trees.
But, when alternative woods began to be imported from developing countries wth cheaper price, these planted trees are left behind and began to destroy ecosystems in Japan's forests ,where Broad-leaved trees had been dominant.
So, use of cedar trees is now promoted to preserve original forest environment in Japan.
Plyscrapers would contribute to the issue.
