The artificial fish deployed by UFP have done it. In just 15 days, the fish have completly cleaned the oceans from any human trash. Dr. Stoci explained that they will not be removed from the oceans, but stay as a permanent "cleaner-upgrade" for Earths oceans. The fish will also be improved with the ability to get rid of oil or other substances in the oceans that shouldn't be there like microplastics.
