19 Winning Photos From Nat Geo's 2016 Nature Photographer Contest That Will Inspire Your Next Trip

"This image is a magnification of plastic particles in eyeliner, exploring just one facet of the synthetic swarm suspended in our oceans. The particles, lash-lengthening fibers, illuminating powders, and glitters these products contain are in fact tiny pieces of plastic. Every time we wash these products from our bodies or ingest them as we lick the glosses from our lips, we unknowingly add to the trillions of microplastic particles currently infesting every level of the ocean. This photograph was taken at Falmouth University in Cornwall, United Kingdom, in May 2016 using a reflective photographic microscope with a stacking panoramic process to create the final image."
