Geopolitical Situation
Amazon is a region in South America in the Amazon’s basin inluding
Lowland Amazon with parts surrounding it:
Guiana Highland
Brazylian Highland
and Ands base
Climate
Amazon occurs in the equatorial climate zone,
which favors the occurrence of ever-greened rain forest .
Average total rainfall during the year is very high,
and the daily and seasonal changes in temperature insignificant.

Amazon fauna is very diverse.
In the Amazon forest lives a huge number of animals, often exceptional and
unique. There are here mostly small species.
The most characteristic animals of the Amazon are numerous species of
monkeys.
According to the National Academy of Sciences, the typical
10 square kilometers of tropical forest live up to 125 species of mammals, 400
bird species, 100 reptiles, 60 amphibians, and even 150 different species of
butterflies.

Amazon rainforest’s importance
• They are called the green lungs of the Earth. The name was obtained through
the production of the world's largest amount of oxygen
• Absorb the greatest amount of carbon dioxide
• Provide water retention, which collect water and store it for a long time
• They are the largest ecosystem of the globe
• There are many tribes living environment, which failed to reach - isolated tribes
Causes of threat to Amazon rainforest.
In order to obtain area for agricultural
cultivation and pastures Amazon forest is
being cut down.
Clearance of the woods is the main
income of residents from indigent
countries.
Acquiring timber from the most valuable kinds of
trees(e.g. rubber plants)
in production of furniture.
Amazon has been torn with roads,
which facilitates the cartage of the timber.
As the demand for gold and other high-minded metals is
rising, the number of mines increases. Waste remaining from
mining spoils natural habitat of many animal spieces.
Outcomes of Amazon Jungle deforestination.
• Increase of average air temperature.
• Petrubation of water menagement- floods, mudslides.
• Annihilation of many, rare spieces of animals and
plants.
• Lack of biodiversity
• Direct finantial costs:
- Report has shown, that losses connected to
deforestation reach 2000-5000 billion dollars a year,
which is 7% of global PKB.
Cutting of forest and situation of Indians tribes
Brazilian National Foundation for the
Indian(FUNAI) estimates that Amazon still live in
68 tribes that have no contact with civilization.In
order to study the Indian, organization using
aircraft and satellites , to avoid contact with them.
It is believed that there is more than 30 different
languages. That makes Amazon more interesting
place.However, hundreds of Indian groups in
South America extinct by the processes of
colonization , disease , and war workers. Today
the biggest threat for those tribes is cutting and
civilized humid Amazon forest .
Worldwide operations in favour od Amazon Forest.
Numerous ecological organisations are running campaigns against rampant
deforestation of Amazon Jungle. By constantly blacking the import of Amazon
timber, those organisations contribute to improving the overall situation.They
also lead some security programs, which control the exploatation of Amazon
forests and encourage to the recultivation of the destroyed areas.
