Welcome to JBCS
The Portuguese writer Ferreira de Castro, in his book "The Jungle", wrote of his impressions of Amazonia at the start of the 20th century, at the height of the rubber boom. The book ends with a great fire that destroys the rubber plantations, which could be interpreted as the end of a cruel period of exploitation, with the light coming from the fire as the possibility of reinventing a new Brazil.
 
Since then, many things have changed, but the social relationships continue, in many situations, as cruel as in the past. The rubber plantations simply gave way to pastures.
 
No one is indifferent when the subject matter is Amazonia. Everyone has proposals to make or opinions to give about the development of the region. The most recent of these proposals, "Amazonia: a Brazilian challenge for the 21st Century - The need for a scientific and technological revolution", was elaborated by the Directorate of the Brazilian Academy of Sciences (ABC). ( http://www.abc.org.br/article.php3?id_article=200 ).
