Half of 6,000 native languages spoken in the world today are likely to disappear in the next 100 years, with her knowledge and techniques of management of the biological diversity of the Earth (LURI, IUCN, UNEP-1992) disappear 200 million indigenous people (5% of the Earth’s population) maintaining biodiversity levels, are the custodians of biological biodiversity of the Earth. Natural survival is the struggle for their habitat. The loss of their ecosystems means the disappearance of biological culture. The importance of the Amazon forest, lies not simply in the effect of abundant rains, nor the intense insolation or rich soil that consumes the forest. Do not. Forest participates in climate, conforms it to through evapotranspiration, the fixation of carbon (on average, seventy tons per hectare), redefining the relationship of incidence of solar radiation with the refraction of that power (albedo).
It intervenes not only in the hydric balance of the region with evapotranspiration as a thermal equilibrium, but it contributes to the dynamic balance of the global climate. Threatened critical areas are located in tropical forests (Mittermier-1992), occupy 1% of the planet’s surface and represent 12% of tropical forests that still exist (expected his disappearance in 40 years), harboring between 30% and 40% of the Earth’s biodiversity. Life is also responsible for the dynamic balance of the planet. the Industrial Revolution. He began to use solar energy accumulated in mineral form, as fossil energy, produced in millions of years of geologic time. Once again, biological life, through an artifact created by man, it interferes in the conditions of dynamic balance of the planet. (Effect greenhouse, ozone layer) by testing their limits. Logic business, private, collides head-on with these principles where the atmosphere is the place of living of what is different, where nature and culture are a contradictorily and complex structured whole.Meanwhile, if the market shows skilled to find mechanisms to reward investments in accordance with its potential risks, not the case with regard to environmental risks.
