Massive boom hopes to corral Pacific Ocean's plastic trash

A ship tows The Ocean Cleanup’s first buoyant trash-collecting device toward the Golden Gate Bridge in San Francisco en route to the Pacific Ocean on Saturday, Sept. 8, 2018. Once deployed, the boom will form a U-shaped barrier to trap plastic and trash that currently makes up the "Great Pacific Garbage Patch." (AP Photo/Lorin Eleni Gill)
