Grad students from Scripps Oceanography Institute traveled to what is known as the "Great Pacific Garbage Patch". What they found was not too pretty.
"About nine percent of the fish that were examined contained plastic in their stomach. That is an underestimate of the true ingestion rate because a fish may regurgitate or pass a plastic item, or even die from eating it. We didn't measure those rates, so our nine percent figure is too low by an unknown amount,"
More research needs to be done in order to determine the level that this plastic will enter the food supply.
