Remarks on the Amazon

10% of Brazilian population
near 20 millions Brazilian
Multi-cultural region
The Amazon is the house 180 indian groups,
several hundreds “quilombolas”, and
uncountable communities of “ribeirinhos”
that are involved in many ways with the
regional economy. The Amazon represents
near 10% of the Internal Growth Product

To understand the biological diversity it is needed to
understand the interactions among ecological,
geological, biogeochemical and evolutionary
processes. Because these interactions are infinite they
possibly occurred only once with the same
peculiarities for a given place and so, local
biodiversity is endemic and specific.

Every fragmented km2 has1.3-1.8
km of border.
Near 20,000 km of new border
appear every year in the Brazilian
Amazon.
Forest borders are highly
vulnerable and the major
source of biodiversity changes.

So …
Organisms are expected to respond to new events as if they are
common events. Hypoxia is a familiar event in the Amazon and so
fish respond to it with adaptations shaped over their existence,
but in the case of anthropogenic pressures these adaptations play
against the animals and kill them.

The hiatus in our understanding of the
relationship between the organisms of the
Amazon and their environment is expressive.
The unknown far exceeds the known.
Beyond the color and forms there are
organisms extremely vulnerable to
anthropogenic effects.
Education, Science and Technology is the
only way to protect the Amazon biodiversity.
