Young Photographer of the Year shortlisted: Ischmeer glacier, by Rory Stringer, Swiss Alps In the 1800s, the entire gorge was covered in ice. Today, the glacier has retreated so much it has resulted in many problems such as unstable rock. The world around us continues to change. Who knows what things will look like in years to come
