SÉRIE GEOLOGIAlDESENVOLVIMENTO SUSTENTÁVEL   

HANNOVER2000


 

 

Recentemente, diferentes temas geológicos têm sido destacados nas emissões postais de diversos países, na maioria dos casos enfatizando minerais, gemas, descobertas paleontológicas, minérios, processos metalúrgicos, recursos energéticos, monumentos naturais e, com menor freqüência, a atividade profissional, personalidades científicas e instituições de ensino e pesquisa.

Este bloco de selos emitido pelos Correios faz uma abordagem de caráter educativo, enfatizando a relação existente entre os fundamentos da ciência geológica e os desdobramentos mais imediatos de sua aplicação, diretamente relacionados com o desenvolvimento sustentável e a melhoria da qualidade de vida da Humanidade.

O conhecimento geológico, além de fundamental para suprir as necessidades de matérias-primas da sociedade moderna, permite, também, conciliar a expansão das cidades e o desenvolvimento industrial com o meio ambiente.

Além disso, praticamente 90% do conforto da vida moderna dependem direta ou indiretamente do reino mineral, portanto, do universo e campo de estudo da geologia. Do automóvel e seu combustível (minério de ferro e petróleo) ao chip de silício e germânio dos computadores, praticamente tudo depende dos recursos minerais da natureza e, por extensão, dos fundamentos e das técnicas da geologia, a exemplo das casas de alvenaria, sua estrutura interna, móveis, utensílios, equipamentos e eletrodomésticos.

A fantástica abundância em riquezas minerais que o Brasil possui foi simbolizada nesta emissão pelo ouro e pelas pedras preciosas (diamante, esmeralda, água-marinha, tópazio-imperial, turmalina bicolor e a brasilianita - esta tipicamente brasileira, de cor verde-amarelada - dentre outros), marcantes ícones da riqueza de nosso país. Por razões econômicas, tecnológicas e de quase exclusividade foi retratado o nióbio, elemento químico metálico utilizado na indústria de alta tecnologia, sendo o Brasil o maior produtor e detentor de 80% de suas reservas mundiais.

A realização do 31' Congresso Geológico Internacional- o mais antigo e importante evento no universo das geociências, que vem se realizando desde 1878 em vários países do mundo a cada quatro anos, e que, pela primeira vez, será realizado na América do Sul, na cidade do Rio de Janeiro, de 06 a 17 de agosto de 2000 - com o tema Geologia e Desenvolvimento Sustentável: Desafios para o Terceiro Milênio coloca o Brasil em destaque no cenário geológico internacional. Esse evento congrega os mais importantes cientistas da atualidade, pertencentes a mais de 80 organizações científicas internacionais, filiadas à União Internacional de Ciências Geológicas, além de reunir representantes e autoridades governamentais de mais de 120 países.

Esta emissão divulga também a Expo Hannover 2000, exposição mundial que reunirá profissionais e empresas de diversas áreas, organizações, associações, instituições e nações em torno do tema "Humanidade ­Natureza - Tecnologia". Com o objetivo de demonstrar que o progresso tecnológico no mundo atual está afetando, de forma irreversível, o equilíbrio da natureza, o evento alerta a humanidade para a necessidade de empregar essa mesma tecnologia para restaurar e assegurar esse equilíbrio.

 

COMITÊ ORGANIZADOR

31 Q CONGRESSO GEOLÓGICO INTERNACIONAL

 


 

GEOLOGY/sustainable DEVELOPMENT SERIES     HANNOVER2000

 

Different geological themes have been recently focused in postage stamp issues of various countries, mostly displaying minerals, gerns, palaentological discoveries, ores, metallurgical processes, energy resources, natural monuments and, less frequently, the professional activities, scientific personalities and institutions devoted to research and education.

This block of stamps issued by the Brazilian Posts presents a didactic approach to the theme, emphasizing the relation between the fundaments of geological science and its most immediate sorts of application, directly related to sustainable development and to the improvement in the quality of human life.

The geological knowledge, besides being fundamental to meet modern society' s needs for raw materials, allows the conciliation of urban expansion and development with the environment.

Furthermore, almost 90% of modern life comfort depends, directly or indirectly, on lhe mineral kingdom; and consequently, on the geology study field. From lhe vehicle and its fuel (iron ore and petrol) to the silicon­germanium computer chips, almost everything depends on nature's mineral resources and, by extension, on geology's fundaments and techniques, as in the example of brick houses, their internal structure, furniture, utensils, equipment and house gadgets.

Brazil's fantastic abundance in mineral resources was symbolized in this issue by gold, precious stones and gems (diamond, emerald, aquamarine, imperial topaz, bicolor turmaline and brazilianite - the latter being typically Brazilian, of a yellish green color- among others), remarkable icons of the natural richness of our country. For economic, technological and exclusivity reasons, this issue also portraits the niobium, a metallic chemical element utilized in the state-of-the-art technology industry, being Brazil its major producer and owner of 80% of its world reserve.

The 31 sI International Geologic Congress - lhe most traditional and important event in lhe Geosciences universe, which has been held since 1878 in many countries every four years, and which will be held for lhe first time in South America, in lhe city of Rio de Janeiro, from Aug. 6 to 17, 2000 - with lhe theme Geologyand Sustainable Development: Challenges for the Third Millenium, puts Brazil in evidence on lhe international geological scene. This event congregates today's most important scientists, members of more than 80 international scientific organizations connected to lhe International Union of Geological Sciences, besides gathering governmental authorities and representatives from more than 120 countries.

This issue also promotes lhe Expo Hannover 2000, a world exhibition that will gather professionals and business enterprises of severa! areas, organizations, associations, institutions and nations around lhe theme: "Humankind - Nature - Technology". With lhe purpose of demonstrating that lhe technological progress in today's world is irreversibly harming nature's balance, lhe event rises human awareness to lhe need of employing technology to restore and guarantee such balance.
