Amazonia


"(...) Because the dynamics of the Amazon River Basin play a major role in environmental conditions that affect the whole Earth, changes in climate and land use in the Amazon take on global importance. During the past 15 years more than 190,000 square miles (1 square mile is about 2.6 square kilometers) of forest have been cleared in the Amazon Basin, and 7,700 square miles are now being cleared each year. Hundreds, perhaps thousands, of future plants, animals, mushrooms, and insects have already been lost. Deforestation alters the ancient forests’ exchanges of water, carbon, and energy with the atmosphere—cycles that even now, we only partially understand. What are the impacts of land cover change in Amazonia both locally and globally?
In 1993, the Brazilian science community, joined by an international team of scientists, began to plan a continental-scale study to answer that question. They established the Large-scale Biosphere-Atmosphere Experiment in Amazonia (LBA) to study how Amazonia currently functions as a regional entity within the larger Earth system, and how changes in land use and climate will affect the biological, physical, and chemical functioning of the region’s ecosystem.

Indios


"Um provérbio indígena questiona se somente quando for cortada a  última árvore, pescado o último peixe, poluído o último rio, é que as  pessoas vão perceber que não podem comer dinheiro." Fechar Janela

"A história
Em 1500, quando os portugueses chegaram ao Brasil, estima-se que havia por aqui cerca de 6 milhões de índios. Passados os tempos de matança, escravismo e catequização forçada. Nos anos 50, segundo o antropólogo Darcy Ribeiro, a população indígena brasileira estava entre 68.000 e 100.000 habitantes. Atualmente há cerca de 280.000 índios no Brasil. Contando os que vivem em centros urbanos, ultrapassam os 300.000.
No total, quase 12% do território nacional, pertence aos índios.
Quando os portugueses chegaram ao Brasil, havia em torno de 1.300 línguas indígenas. Atualmente existem apenas 170. O pior é que cerca de 35% dos 210 povos com culturas diferentes têm menos de 200 pessoas. (...)" (www.webciencia.com)

Dez anos depois de ser reconquistada pelo povo Kiriri, a pequena Mirandela, na Bahia, vira exemplo de preservação cultural
 
RITMO QUENTE
Antes relegados à pobreza, os indígenas de Mirandela hoje festejam seu ressurgimento cultural
Não seria de se estranhar que em pleno mês de novembro uma cidadezinha baiana tivesse o silêncio da manhã interrompido por batuques e cantos." http://www2.uol.com.br

Raconte-moi la terre / Tell me the earth


...Telle que tu souhaites qu'elle soit quand tu seras grand / ... Such as you wish that it be when you will be tall

Et eux, qu’en pensent-ils ? Comment la rêvent-ils, tous ces enfants des villes ou terres meurtries voire dévastées par la pollution, la surpopulation, la radioactivité… ?
Mais y croient-ils seulement ? ou peut-être imaginent-ils un moyen pour éviter ces catastrophes que l’on leur prédit à toute heure : réchauffement atmosphérique, fonte des glaciers, cataclysmes météorologiques, extinction de races animales et disparition d’espèces végétales, mutations génétiques...

The Earth is sick, it enough is said to us, and that is seen. How that will it evolve? Conscious of the threat, will we react in order to bequeath to our children a nature healthy and suitable to carry them, nourish them, protect them?

And them, what do they think about it? How do they dream it, all these children of the cities or ravaged grounds even devastated by pollution, overpopulation, radioactivity...? But do they believe in it only? or perhaps they imagine one way to avoid these catastrophes that one predicts to them at any hour: atmospheric reheating, cataclysms weather, extinction of animal races and disappearance of vegetable species, genetic changes...
