An expedition to the Marshall Islands with the 5 Gyres Institute to free the oceans of marine plastics served as sparkplug for 27-year-old scientist Kristal Ambrose of the island of Eluethera in the Bahamas. Upon her return, she began hiring local students for beach cleanups, and thus the Bahamas Plastic Movement was born. She now successfully runs a 5-day youth summer camp, training and educating the younger generation on plastic pollution and trawling for plastic waste on the island. Photo credit: Elyse Butler
