Science To widen beaches, some cities pump offshore sediment onto them. How might this affect organisms that live in coastal waters? Asked by arwen46 12 years ago 2/2/2013 5:13 AM Last updated by anonymous 12 years ago 2/3/2013 7:39 PM
By pumping offshore sediment to widen beaches cities affect the organisms living in coastal waters by upsetting their habitats by changing the way they get food as well as where they make their dwellings.
