Writing
Make
a
list
of
things
you
can
do
to

greener
and
give

Turn
off

when
you
don’t
need
them.
Don’t
print
out
so
many

and

It’s
our
duty
to
make
a
greener
school.
We
are
supposed
to
do
something
to
create
an
environmentally-friendly
campus
for
all
of
us.
Firstly,
it
is
important
to
turn
off
the
lights
when
we
don’t
use
them
so
that
less
energy
can
be
used.
Secondly,
we
had
better
buy
food
with
less
package
because
plastic
is
the
major
cause
of
pollution.
So
we
can
reduce
the
amount
of
plastic
which
is
very
contaminating.
Last
but
not
least,
we
should
recycle
paper
and
bottles
so
that
we
can
save
energy
and
resources.
Although
we
can’t
hope
for
rapid
change,
some
steps
have
to
be
taken
so
that
our
school
will
become
better
and
better.
