The trade in demolition timber is a responsible way to use noble timber in a rational way without environmental aggression. Even today lumber of dubious origin is traded on a large scale and most often from illegal or criminal extraction, which results in irreparable damage to nature, annihilating several species and even in many cases reach extinction. But for us to be a little more relieved, these irregular forms of deforestation have been counting, because although they are still evident, there has already been a great fall, thanks to politicians and serious entities and their rigid deal with these crimes. The processes that are being implemented range from intensive combat in the regions dominated by the noble and influential entrepreneurs, to the control of m³ that reaches the retail market, through strict inspection of the areas of extraction and tracking by volume during the entire journey until arriving to the final consumer, all monitored for absolute control.
