假如你是李明，你们学校要举办一次关于“我们为什么要保护野生动物”的演讲比赛，请你根据提示写一篇80词左右的发言稿。
提示词语：wild
animal（野生动物），in

protect,

in
the
balance
of
nature,

important
Why
Should
We
Protect
Wild
Animals?
Why
Should
We
Protect
Wild
Animals?
Many
wild
animals
are
in
danger
now.
I
thin
we
should
protect
them.
First,
we
should
realize
that
they
are
our
friends.
We
need
them.
They
live
with
us
on
the
earth
together.
If
there
are
no
animals
on
the
earth,
we
will
not
live
on
the
earth,
either.
And
once
they
are
gone,
there
will
never
be
any
more.
Second,
every
animals
has
its
place
in
the
balance
of
nature.
Destroying
one
kind
of
animal
can
create
many
problems.
All
in
all,
wild
animals
are
important
to
us,
so
protecting
them
is
also
protecting
ourselves.
