The geology of Brazil’s volcanic
trindagi island has fascinated
scientists for years.
but the discovery of rocks made from
plastic debris in this remote total
Refuge is sparking alarm. as researchers
say that it’s evidence that humans are
influencing Earth’s geological cycle.
here’s a report.
this is the Brazilian island of chandaji.
its geology has fascinated scientists
for years , but the latest discovery on
this remote Turtle Refuge has terrified
them.
these rocks are made from plastic debris,
melted plastic has become intertwined
with rocks on the Island located more
than 700 miles away from the mainland.
and scientists say it’s proof of
Mankind’s growing influence over Earth’s
geological Cycles.
trindagi island is one of the world’s
most important conservation spots for
green turtles, with thousands arriving
each year to lay their eggs.
the Island’s only human inhabitants are
members of the Brazilian Navy . which
maintains a base in the island and
protects the nesting Turtles.
but its remoteness did not stop human
activity from interfering.
the place where we found these samples
of plastic is a permanently preserved
area in Brazil near the place green
turtles lay their eggs.
it has a unique biodiversity with
endemic species of fish, coral reefs,
Marine birds and protected species of
crab for example.
researchers at the federal University of
piranha couldn’t classify the Rocks , so
they ran chemical tests which found that
the Plastics in the rocks are called
plastoglomerites , made from a mixture of
sedimentary granules and other debris
held together by plastic.
we identified pollution mainly comes
from fishing nets . which is very common
debris on trendagi Islands beaches . the
Nets are dragged by the Marine currents
and accumulate on the beach.
when the temperature rises this plastic
melts and becomes embedded with the
Beach’s natural material.
Santos says the discovery stirs
questions , about humans Legacy on Earth.
we ran a chemical analysis to know the
kind of plastic and we also addressed
these samples as if they were natural
rocks , using the same research methods.
then we observed them in a macro and a
micro way and described the samples as
rocks.
this is also part of the discoveries of
our work . marine pollution seen from the
geology perspective, this is new and
terrifying at the same time because
pollution has reached geology and
plastic can be preserved in the geologic
report of the Earth.
