What does corruption, the
pollution of urban rivers and the not-so-recent shark attacks on swimmers in
Recife have in common? - Everything.
Let's start by sharks - before the construction of the port of Suape we had no record of these attacks
in the waters of the reef, so the most logical thing would be to blame the
situation created by the arrival of the port and its environmental impacts, but
that does not seem to be the determining factor.

In the documentary
"Shark Rebellion," presented on the Discovery Channel, Lawrence Wahba
investigates the attacks and identifies the culprit species, the Bull Shark
(Carcharhinus leucas). Wabba dive with these sharks in Cuba and they seem to be
extremely quiet, the biologist gets really surprised by the peacefulness of the
animals in Cuba.
The Carcharhinus
leucas has a pattern of eating rather passive, they seek their food that arise
in abundance in coral reefs and they hardly spend energy on attacks to feed.
This seems contradictory to what happens in Recife, for devouring men requires
a great deal of energy in the attack.
Why does then the Sharks
attack the beachgoers?
In the same
documentary Wabba realized that the beaches in Cuba, with clear waters has an
abundance of small fish, carcasses and other passive food for sharks. But in
Recife, the pollution dumped on beaches by polluted rivers, made murky the waters,
and decimated much the presence of fish and other passive food for the Carcharhinus
leucas. The scarcity of this food has taken the animal out of his comfort zone
to attack swimmers. That became the only option.
To pollute rivers of
big cities is undoubtedly the least intelligent practice that the public
administration and the private sector can do. You could say that whomever does
it not differ from the one who defecates by the door of his own home.
Worse yet, to
compromise the already scarce reserves of fresh water on the planet, man
creates himself the additional problem of water shortages and to threaten
hydropower generation (see the problem that affects Cantareira water supply system
in the State of São Paulo).
Why then do we continue
to make that mistake that bad?
Simply because
investing public money in sanitation does not generates votes. Added to this
corruption at all levels of administration, which undertakes these works that
are very expensive and too slow to be completed. The amount of disease caused
because of this lack of sanitation is huge and ultimately affects education
because sicker children miss classes.
The child with the education
deficit becomes the adult with deficiency in environmental perception, and this
cycle tends to continue until something more dramatic happens.
It's a shame that most
politicians do not surf in Recife, since the shark attack to one of them, would
be the best way to close this cycle, and who knows, the commotion caused by the
tragedy, would lead to a review of their concepts, and could end the bad Brazilian
habit of polluting rivers in almost all urban centers.
While a Brazilian
beast does not revenge the so worn class (corrupt politicians), ‘The Bruzundanga
saga’ hero, Assum Preto, a sensitive and violent 'cangaceiro' seems to be the
only option of solace for Brazilian people, lol.
