Polluted water is bad to both us and the environment. Water pollution damages rivers waters with toxins and enough of it can kill all life and make it stink. For us, however, we might make sure that the water is safe first before 1) we drink it or 2) to swim or fish in it. For the river though, it'll take years to clean up the pollution in the contaminated river.

I think polluted water is dangerous to human beings! Only when we realize the serious situation can we save ourselves.

Yes,I agree. Polluted water is very bad,and kills a lot of sea animals. Besides that, sickness could get worse and spread.

And like swine flu, the pollution sickness could make its way to human body/lungs.

Amen! I agree with you!

In my opinion, polluted  water  is not good for humans or animals or any living thing because the pollution could kill them or  make them sick.
