The world’s oceans are clogged with plastic debris, but how much of it finds its way into the seas annually? Enough to place the equivalent of five grocery bags full of plastic trash on every foot (30 cm) of every nation’s coastline around the globe.
That’s according to scientists who released research on Thursday estimating that a staggering 8 million metric tones of plastic pollution enter the oceans each year from the world’s 192 coastal countries based on 2010 data.
Based on rising waste levels, they estimated that more than 9 million tons would end up in the oceans in 2015.
Experts have sounded the alarm in recent years over how plastic pollution is killing huge numbers of seabirds, marine mammals, sea turtles and other creatures while sullying ocean ecosystems.
