Rebecca

Despite living in a relatively rural place, Rebecca highlights the unstoppable tide of fast food in the area: one particular global chain has three outlets within a mile radius, one of which is a five-minute walk from school. "I absolutely believe this was done on purpose, and it's extremely detrimental to child health," says the young campaigner, based just outside of Sheffield. "I hate the fact that schools are flooded with takeaways. But we're all oblivious to it."
