Winner, adults category: What’s on the Menu by Sam Oakes, Richmond, Surrey.

“Our everyday decisions impact not only our local environment but those distant from us, in this case the watery home of the puffin. Human decisions are depleting sand eel availability and changing the fish species on the puffin’s menu, day in, day out, an impact all too plain to see whilst I spent several weeks out on the Isle of May [in Scotland] this summer.”
