Kauri is dominantly imported from the Philipinnes and Australia where it is extracted from the tropical rain forest . The deforestation of tropical wood causes serious local environmental problems and is related to the climate change in the world. The transport to the Netherlands requires 2 * 250km by trailers (from factory to forest and back) and 10442km by ship.
