10 rivers may deliver bulk of ocean plastic
by Russell McLendon
As much as 95 percent of the plastic waste that reaches oceans via rivers is carried by just 10 waterways, according to a new study.
Earth's oceans have a big plastic problem. They receive roughly 8 million metric tons of plastic waste every year, much of which can drift around for decades or centuries without truly decomposing. Instead, it just crumbles into smaller pieces known as microplastics, which often fatally trick marine wildlife into eating them.
