Save
the
Sharks!
Many
have
heard
of
shark
fin
soup.
This
famous
and
expensive
dish
is
especially
popular
Sharks
are
endangered
in
southern
China.
But
do
you
realize
that
you
re
killing
a
whole
shark
each
time
you
enjoy
a
bowl
of
shark
fin
soup?
When
people
catch
sharks,
they
cut
off
their
fins
and
throw
the
shark
back
into
the
ocean.
This
is
not
only
cruel,
but
also
harmful
to
the
environment.
Without
a
fin,
a
shark
can
no
longer
swim
and
slowly
dies.
Sharks
are
at
the
top
of
the
food
chain
in
the
ocean
s
ecosystem.
If
their
numbers
drop
too
low,
it
will
bring
danger
to
all
ocean
life.
Many
believe
that
sharks
can
Help

the
sharks
never
be
endangered
because
they
are
the
strongest
in
their
food
chain
but
in
fact,
around
70
million
sharks
are
caught
and
traded
in
this
industry
every
year
The
numbers
of
some
kinds
of
sharks
have
fallen
by
over
90
percent
in
the
last
20
to
30
years.
Environmental
protection
groups
around
the
world,
such
as
WildAid
and
the
Something
about
WWE,
are
teaching
the
public
about"finning.
They
have
even
asked
governments
to
develop
laws
to
stop
the
sale
of
shark
fins.
So
far,
no
scientifc
studies
have
shown
shark
fin
soup.
that
shark
fins
are
good
for
health,
so
why
eat
them?
Help
save
the
sharks!
