Last Sunday my fathr and I wnt fishing along a rivr. W found th watr so dirty that w could hardly catch fish in it.

A lot of factoris along th rivr always pourd thir wast watr and rubbish straight into th rivr which mad th rivr watr pollutd. In this way most of th fish in th rivr wr killd.

If th rivr watr all ovr th country is pollutd lik this， no living things will xist in th watr. As w all know， nvironmntal pollution dos grat harm to living things and human bings. Now mor and mor popl hav com to raliz how srious this problm is. Our govrnmnt is doing hr bst to tak masurs to fight against pollution. W xpct that th watr in vry rivr will b mad clanr and clanr bfor long.
