A hermit crab crawls atop a pile of plastic in a shell made from manmade waste. Photographed on the small island of Thanburudhoo in the Maldives, photographer Matt Sharp hopes his image communicates the direct impact plastic pollution is having on the natural world: “We were so shocked at the plastic waste littering the island. And then I saw this hermit crab crawling through the knee-deep plastic. It demonstrates the scale of the problem.”
