"Nadia Sparks, a 13-year-old student from Norwich, got juice thrown at her face, was chased and punched, even shown a knife by schoolmates only for picking up litter on her way to school and was named "Trash Girl."

Undeterred of all the bullying, she has picked up thousands of liters of garbage since she started her project, much of which has been recycled. After her story went viral, she became an ambassador for the WWF and has won international recognition & awards."
