What would be affected negatively by contaminated watersheds? crops
sewers
chemicals
water cycle

Explanation:

I believe the water cycle would be affected negatively.

world war i had a devastating effect on german-americans and their cultural heritage. up until that point   german-americans, as a group, had been spared much of the discrimination, abuse, rejection, collective mistrust experienced by so many different racial and ethnic groups in the history of the united states. indeed, over the years, they had been viewed as a well integrated and esteemed part of american society. all of this change with the outbreak of war.  

no because it could make the world a terrible place to live in.
