Because
humans
took
rats,
cats
and
rabbits
to
the
island
unknowingly,
there
were
fewer
birds
left
on
the
island.
In
order
to
deal
with
the
rat
problem,
cats
were
brought
here.
Unfortunately,
they
led
to
fewer
birds
too.
Meanwhile,
since
rabbits
were
brought
here
as
food
for
people,
they
caused
landscape
destruction.
