That's because it's not there. It's down at the bottom of the oceans and seas.
The discovery of microplastic in such remote marine habitats raises new questions about the potential for plastic debris to contaminate the food chain. Scientists have already documented that fish, birds, turtles, and other marine animals eat plastic. Thompson and his team found an even greater accumulation of plastic than previously suspected. The more plastic there is, he says, the more potential for toxicity to marine life.Isn't this wonderful news?
In the study, Thompson and his team concluded that every square kilometer of deep ocean contains about four billion plastic fibers—most are two to three centimeters in length and as thin as a human hair. The fibers are four times more abundant in the deep sea than in surface and coastal waters.
"Our results show evidence for a large and hitherto unknown repository of microplastics," Thompson wrote. "The prevalence of microfibers in all sediment cores and on all coral colonies examined suggests this contaminant is ubiquitous in the deep sea." source
