Scientists and volunteers who have spent the last month gathering data on how much plastic garbage is floating in the Pacific Ocean say most of the trash is medium to large-sized pieces, as opposed to tiny ones. Volunteer crews on 30 boats have been measuring the size and mapping the location of tons of plastic waste floating between the West Coast and Hawaii. Three of the boats, including this 171-foot mother ship, returned to San Francisco on Sunday, Aug. 23, 2015. (The Ocean Cleanup via AP)-
