Forests services are for free, for this reason we hardly imagine their real value
Forests provide food (fruits, seeds, vegetables, game), vegetable fibers, raw materials. Many of the prescription drugs used in the western world have been derived from plants and 70% of the plants identified as having anti-cancer characteristics by the US National Cancer Institute are found only in the tropical rainforest. Scientists believe that the answer many of the major diseases, like AIDS, tuberculosis, has to be found in the rainforests. Forests are huge libraries, as well as a science laboratory in continuous progress.
Forests have enormous hidden values, and their destruction have enormous hidden costs.
