water pollution

　　      with  the  development  of  industry,  water  pollution  is becoming more serious now. the polluted water not only kills fish, it is also harmful to our health.  many people get sick because they drink the polluted water. in some rivers the water is so dirty that they can even kill plants.

　　     we should fight against the pollution. we should stop using harmful things. i wish it is not a dream that in the near future we can have clean rivers again.
