pollution
is

The

ways
to
solve
the
problem…
One
possible
version:
Air
pollution
is
becoming
more
and
more
serious
in
today’s
world.
Some
chemical
factories
produce
terrible
gas
and
make
the
air
bad.
Buses
and
cars
also
produce
waste
gas.
In
our
daily
life,
burning
gas,
oil
and
coal
also
creates
air
pollution.
The
air
pollution
may
cause
a
lot
of
problems.
It
is
harmful
to
people’s
health.
It
can
cause
breathing
problems,
sore
eyes
and
even
cancer.
It
can
also
harm
the
plants,
and
the
farmers
will
get
less
harvest.
Luckily,
the
government
has
tried
many
ways
to
solve
the
problem,
such
as
making
laws
to
prevent
the
factory
from
polluting
the
air.
