Despite all the changes that had to suffer our ecosystem, nature is wise, andfor this reason that we have not yet self-destroyed. Today the world is suffering from pollution, and damage caused by man are irreversible. Still time for human beings become aware of the urgentneed to manage the use of rational means.
