A primary forest is a virgin forest that has never been touched by the hand of man; its
fauna and flora is so varied that it is calculated that only 14% of its species have been
identified. More than half of virgin jungles are found in the tropics with 80% of the world's
biodiversity; it is fundamental to regulate carbon emissions for natural resources and the
climate. The protection of these forests is a matter of survival, but it is not related to simply
protecting an isolated wooded area since it is important that species are free to move
around. Take the example of the ''Corredor del Jaguar'' that links 13 countries from Mexico
to Argentina, passing through Costa Rica, joining different jaguar populations to prevent
extinction. The primary forest in Corcovado National Park has fifty specimens (15,000
estimated in the world).
