About Brazil
Covering almost half of the
South American continent, Brazil is home to over 60,000
different plant and animal species. There are twelve
species of mammals in existence in the western hemisphere, eleven of which
can be found in Brazil. It's terrain and climatic regions
are almost as diverse as its biodiversity. Five separate climatic regions
make up its territory: equatorial, tropical, semi-arid, highland tropical
and subtropical. Rainforests exist to the northwest,
(namely within the Amazon Basin) and along the Atlantic
coast (forming the Atlantic Forest).
The Amazon River Basin alone accounts for about
40% of Brazil's national territory. It is an area
so rich in biodiversity that up to 3,000 species can exist within one
square mile. Western-Central Brazil gives way to woodland
savannas, used primarily for soybean cultivation. Set
between the lowlands and the savannahs are dense swamplands formed by
flooding in the Paraguay River Basin. To the northeast
lies the caatinga or semi-arid region covering hundreds of thousands of
miles. It has suffered major degradation due to human encroachment and
subsistence activity.

The Atlantic Forest is a composite
of great species richness as well. At one point it spread across 1.4 million
square kilometers. Today, only 7% of this original
expanse remains.Its geography permits high density of flora including
mosses and orchids among others endemic to its humid conditions.
Agriculture is considered a central threat to its survival
as poor economic conditions rapidly posed the threat of deforestation
due to an increase in timber sales. A UNESCO
Biosphere Reserve has helped to greatly alleviate the pressures of human
activity within this area. Subtropical Pine forests
to the south along with notable Mangroves and a rocky interior all contribute
to the varying terrain and diversity of Brazil.

People have played a large role
in carving the face of this territory for centuries. The ethnic mixture
includes many Caucasians of European decent originating from Portugal,
Germany, Italy, Spain, and Poland. The next largest group is made up of
those with mixed Caucasian and black heritage. 6% of the population
is black; the remaining 1% are Japanese, Arab, and
Amerindian.

Having such an amazing natural resource
base, and a population of over 175 million people, sustainability
goes hand in hand with survival in Brazil. One of the most pressing environmental
issues lies in air and water pollution in large cities such as Sao Paolo
and Rio de Janeiro. Brazil's resource base makes it
a prime player in the global market place. National
products include Bauxite, Nickel, Quartz, Platinum, and Titanium among
others. In fact, Brazil's known iron deposits are large
enough to meet global demands for the next 20 years.
The country's eight hydrographic basins demonstrate its enormous capacity
for hydroelectric power generation. As seemingly inexhaustible
as its resources are, the rate of their destruction is tantamount to consumption
on a global scale. Destruction of the Amazon Basin remains one of the
country's most urgent environmental issues, This destruction
continues to place the existence of many species under constant pressure
including the Spotted
Jaguar, the Golden
Lion Tamarin, Spix's
Macaw, the Amazon
River Dolphin, the Bald-headed
red uakari, and the Keel-billed
toucan, among others. There are 24 species of fauna
in all currently considered on the brink of extinction in Brazil.
