Where humans and their cultures have emerged from their adaptations, their knowledge of their use. to biodiversity are two inseparable dimensions: the Biological and cultural. Thus a property of living things and that makes them different cultural and unique. a 50-80% of the planet's biodiversity is found in tropical countries (Brazil, Colombia, Mexico, Zaire, Madagascar and Indonesia), who have suffered in the last 100 years, huge losses of tropical forests and the disappearance of Indian population at the rate of one tribe each year. Half trachea 6,000 native languages are spoken in the world today are likely to disappear within the next 100 years, with her knowledge and skills will disappear management of biological diversity on earth (UNL, IUCN, UNEP-1992) to 200 million indigenous people (5% of the population of the earth) maintain levels of biodiversity, are custodians of the biodiversity of the earth. The struggle is their natural habitat for survival. The loss of ecosystems means the disappearance of the biological culture. the importance of the Amazon forest is not simply of the effect of heavy rain or intense sunshine and rich soil consumes the forest.
No. The forest part of the climate as shaped by evapotranspiration, carbon fixation (average, seventy tons per hectare), redefining the relationship of incidence of solar radiation with the refraction of that energy (albedo). Speaker, not only in the water balance in the region with evapotranspiration as a thermal equilibrium, but contributes to the dynamic equilibrium of the global climate. threatened critical areas are located in the tropical forests (Mittermier-1992), occupy 1% of the planet's surface and represent 12% of tropical forests still exist (providing for their disappearance in 40 years), housing between 30% and 40% of the biodiversity of the earth.
