Many governments of developing countries consider that croplands and pastures are more valuable than forest, so they harvest the most valuable timber, turn the smaller trees into charcoal, and burn the rest. Often the whole forest is razed to the ground and burned. Not only does the timber thus become a non-renewable resource, but many other valuable species are lost, for only a handful of scientists know what these valuable non-timber species are, and only rarely has the information been made available to governments.
