Wengé is dominantly imported from tropical Africa. The wood is not cultured. 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 5748km by ship.
