Lilly Platt is a 13-year-old England-born, Netherlands-based climate activist who centers her work around reducing plastic pollution through her initiative called Lilly’s Plastic Pickup. According to Global Citizen, in 2015, after Platt and her family moved to the Netherlands, she went on a walk with her grandfather and, in an attempt to improve her language skills, decided to count pieces of plastic. “We counted 91 pieces of plastic in only 10 to 15 minutes,” Platt told Global Citizen. Her grandfather explained to her that the plastic garbage then makes its way into the ocean to become “plastic soup,” according to an interview with Earth.org. This led to Platt starting Lilly’s Plastic Pickup, through which Platt goes on regular trash pickups, sorts the trash and “take[s] pictures of them and post[s] them on social media,” according to an interview with Global Citizen.
