AMAZON FOREST, INFINITESIMAL
CONSIDERATIONS.
José Luiz Pereira da Costa
Conferência na Washington University,
Saint Louis, Missouri, 9 de março de 1990.
Marco Antonio General Secretary of our Y.M.C.A. gave us the advice: we have
to be prepared to talk about two issues of major interest nowadays in the U.S.A.:
The deforestation of Amazon Jungle and Brazil's multi-billion debt. The Brazilian
debt is, somehow, a relatively new issue. The Amazon Forest, nevertheless, is
a very old subject discussed time to time. Probably the public opinion in the
U.S.A. is concerned nowadays about the Amazon Forest because opinions of the
U.S. Senator, Albert Gore. Early this century Amazon was in the stage because
a frustrated Fordland, a dream of Henry Ford. Now, in the fall of 1987, a Commission
with the members Albert Gore, Tim Wirth and John Heinz made, to say viciously,
an important finding, with the support of a Dr. James Hansn, NASA Chief of Godard
Institute for Spatial Studies: That the greenhouse effect has reached to the
heart of US Senate, and immediately made the temperature in the House climb
up to as far as 99 degrees Fahrenheit! Amazon was the responsible. Immediately
was raised the hypothesis suggesting that the Greenhouse Effect was generated
by fires in the Amazon Forest. Fires producing, they said, too much Carbon Dioxide
(C02). Enough to provoke a hecatomb in the whole Planet, such as deice in the
poles, just few decades ahead. The Senators have visited Rondonia State (in
deep Amazon area) toward the end of 1998. The visit was to show their disappointment
for the assassination of one regional union leader, Chico Mendes, and, as well,
to see themselves, the extent on forest devastation by forest burns, along the
BR-364, a federal highway. They became disappointed indeed. They could½ðt see even
one single forest burn. This was just because of one simple and very well known
reason, among the Amazonians: they have arrived in December during the water’s
season. The forest burns can only be seen for a short period, in fact two months:
August and September, in Rondônia. September/October in other subregions. In
the remaining months the forest lays submerged in the immense green harmony
of rains and thunder rumbles. From the moment the U.S.A. Senator returned home
a red warning light was turned on: intellectual, scientific, political, diplomatic
media circles start to mobilize themselves and the public opinion with a clear
message: we ought to preserve the Amazon Humid Tropical forest to save our Planet.
After it, old stories, half-truths and, to be just fair, some realities about the
Amazon environment where thrown at the international table, generating, for sure panic,
anxieties, public movements, civic meetings, forums, symposiums, preachers' sermons,
all idiosyncrasies and ideologies. The game of tensions has reached to a so high level that the U.S.A.
Republican Senator Bob Kasten said emphatically: when environment is the question,
and more if is the Greenhouse Effect, national borders are irrelevant.
GREENHOUSE EFFECT.
The Greenhouse Effect is the resultant of a group of natural
physic-chemical actions from the absorption, by lower atmosphere stratum, making
higher, consequently, the ambient temperature. The retention of the heat in
the earth atmosphere, that stops the flux of infrared radiation, would be the
result of high concentration of Carbon Dioxide (CO2) and other gases generated
by the burning of carbon, petroleum, natural gas and others. Now if one goes
to any serious study, made up based in scientific research, will find that the
contribution of Brazilian Forest Fires for the Greenhouse Effect is of no significance.
The time Magazine, in January, 2nd, 1989 produces a large and serious report,
with many objectivity, passion, showing that the main responsible agents for
the atmosphere contamination are not in the Humid Forest. The world champions
are the U.S.A., holding 22.8%; The Soviet Union with 18.87%, the whole Europe
with 21.53% and Brazil, after Japan, China, Canada, with only .93%. The important
contribution for the said Greenhouse Effect is not from the Forest burns, but
cars, house heaters in cold countries, factories, and coal electricity plants.
WORLD'S LUNG.
As is said nowadays concerning the Greenhouse Effect, in
the 70's scientists and newscasters kept saying that the Amazon Forest was responsible
for the generation for more than half the oxygen. Because of this was said,
the deforestation could cause the dead by asphyxia of the whole biosphere. At
the time, as now, was said that the Amazon Forest would have been internationalized,
to preserve the survival of the whole humanity! Today any serious person, talking
about this subject supported by knowledge and genuine interest, will recognize
as false the stories about Amazon world's Lung. Scientists know that the Amazon
Forest is not a young Forest. Because of this it generates, by photosynthesis,
the oxygen it uses. A young forest will produce more oxygen than it requires.
Is not the Amazon nowadays status. There we have a mature Forest.
FEW WORDS ABOUT THE GIANT.
The Amazon region is a gigantic frontier. The widest portion
of the Brazilian Territory. In a sight from the space the South American Amazon
represents 1/20 of the earth surface; 2/5 of the whole South America; 3/5 of
Brazil's Territory (8,400,000 sq kilometers). The Amazon has 1/5 of the world's
available drinkable waters and 1/3 of the forests. But is opposition the Amazon
has 3,5 millesimal portion of the world's population. Brazil has 63.4% of the
South American Amazon Forest and shares it with another 7 Countries. The size
and position of the Amazon Forest make it, along the years, both attractive
and inaccessible. The economic value and strategic of the jungle is clear, making
to rise, time after time, the theory of its internationalization under the face
of different projects. Doubtless, Brazil need to expand its agricultural frontier
to feed its now 160 million inhabitants. Brazil cannot ignore all the riches
under the green cover of the trees in the forest; iron, manganese, bauxite,
platinum, silver, cooper, gold and diamonds, to say few. Brazil cannot just
preserve more than four million square kilometers as the Botanic Garden of our
Planet, while his people suffer hunger, disease, illiteracy and all the problems
of underdevelopment and poverty. On the other hand, inside Brazil there is many
people interested in environmental questions, and, for sure, Amazon is one of
their major preoccupations. There are groups who fight against government projects
for roads and highways across the Forest. There are groups fighting against
the gold miners. Groups to preserve important animal species. People against
and in favor of new dams, to generate electricity to the Country and to avoid
near collapse. There are groups in defense of the Indians living in areas rich
in minerals that they can't exploit. There are groups outside the Country making
pressure on international credit entities to boycott credits to Brazil. Just
now there is many pressure, is said from U.S.A. to avoid a long term Japanese
credit, to permit the construction of a highway, across a part of the forest,
enabling Brazil to be connected with Pacific Ocean, via Peru. This is almost
the same thing you have in U.S.A., concerning abortion, Indians, Negroes, homeless,
drugs and so on. And you know better that the majority that the forum for such
discussions is the United States Capitol, where as you use to say, we the people,
are there. So, what Brazil is very much concerned is to find, using its representatives
bodies, like the Brazilian Congress, avenues for the future of our Amazon Forest.
Finally, I'll take in consideration the following two points:
1 - Developed Countries of today, like the
U.S.A. has changed its natural environment with no care, to give the fruits
of development to its inhabitants. In fact, as said before, even today, the
U.S.A. is the biggest pollution generator in the world. 2 - Brazilian
authorities seems ready to find ways of cooperation that may lead to an intelligent
use of the Amazon Forest, even because is clear that any project will require
many economic resources, what, as everybody knows, is not available there, by
now. One thing is very much important to know: Brazil is not thinking in convert
the whole Amazon Forest in a gigantic factory of oxygen, rain and thunders for
the pleasure of the rest of our planet. Amazon will mean more than just it.
Thank you.
