Paris Mayor Anne Hidalgo wants to host Olympic swimming events in the Seine River for the 2024 games. But to do so, she’ll have to clear the river of its vast waste — about 360 tons of plastic are found in the Seine every year. But 10-year-old Raphael has dedicated his free time to fishing waste out of the river using a magnetic rod. He’s already managed to fish out 7 tons of waste, including electric bikes, scooters, scrap metal and cell phones.
