I’m
worried
about
the
future.
Pollution
is
our
great

to
fight
it.
If

farmers
can’t
use
water

pollution
from
factories
spreads

them.
Pollution
is
a
danger
to
our
health.
B:And
there’re
so
many
cars
on
the
road.
They
use
so
much
oil
and
cause
pollution
as
well.
D:But
we
are
only
students.
We
can’t
do
anything
about
factories
and
cars.
B:
It’s
no
use
talking

we
can’t
do.
We’ve

green
school?
L:
At
a
green
school,
every
class
collects
waste
or
rubbish
which
can
be
recycled
or
used
again.
Then
the
school
sells
the
waste
and
uses
the
money
to
help
students
in
poor
areas.
D:
Nice
idea!
B:
Students

That’s
a
good
idea.
Though
pollution
