Today, on World Oceans Day, our planet’s seas are choking on junk: Soda bottles, plastic bags and tons of cigarette butts. Distant spots in the ocean — called garbage gyres — have become vortexes where humanity’s trash bobs atop the water for miles on end.
Worse yet, the filth floating on the surface accounts for only 5 percent of all the plastic trash dumped into the sea. The other 95 percent is submerged beneath, where it strangles underwater creatures and wrecks the aquatic ecosystem.
