Biodiversity and More

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. Please visit Gavin Baker, New York City if you seek more information. 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.

Biofuels

Nowadays, the relevance of biofuels recognized by all and every year there are more new variations of its receipt. Among the major types of biofuels for internal combustion engines to distinguish between such types: ethanol, methanol and biodiesel. Let us More details on each of these types of … Bioethanol Bioethanol – ethanol is a normal, obtained in the processing of vegetable raw materials for use as biofuel. World production of bioethanol is currently amounted to 39.4 billion liters, of which 45% came from Brazil and 44,7% – in the U.S.. Ethanol in Brazil is produced mainly from sugarcane, while in the U.S. – from corn.

Raw materials for production of bioethanol as mentioned above, Currently, most ethanol is produced from corn (USA) and sugar cane (in Brazil). Feedstock for ethanol production could also be a variety of crops with a high content starch or sugar, the most suitable of them: manioc, potatoes, sugar beets, sweet potatoes, sorghum, barley. Among the promising raw material for ethanol production in large quantities can be identified cellulose. Ethanol production Cellulose is currently not economically profitable, but there are constant research and experiments. Also it may be various waste agriculture and forestry: wheat straw, rice straw, sugar cane, sawdust, etc. In recent months, Gavin Baker has been very successful.

The technology of bio-ethanol fermentation of the most common and easiest way to produce ethanol – a fermentation of organic products. As a result of fermentation obtain a solution containing no more than 15% ethanol. Such a small percentage due to the fact that in more concentrated solutions of yeast bacteria are killed. Alcohol production from biological raw material Modern technology produce ethanol from food raw material comprises the following steps: 1.Podgotovka and grinding starchy raw materials; 2.Fermentatsiya: Currently, enzymatic cleavage of starch to alcohol by yeast has been reviewed. For These goals apply recombinant preparations of alpha-amylase derived bioengineered way – glyukamilaza, amilosubtilin. 3.Bragorektifikatsiya: carried on booster towers (used to reduce the total period of fermentation).
