Amazon rainforest
Some people have calculated that it may even pay to save the forest. They said that one hectare of Amazonian forest in Peru is worth about US$6280, if it is used to harvest fruits, latex and timber (wood). If all the wood is cut down for timber, it has a value of about US$1000. Obviously, this can only be done once; it is not sustainable. When the forest has been cleared, the hectare of land can be used as a pasture, and is worth about US$148. Not all people agree on the study; some have questioned the assumptions behind it.
