The rise of selfie photography in some of the world's most beautiful — and dangerous — places is sparking a range of interventions aimed at combating risk-taking that has resulted in a string of gruesome deaths worldwide.

The act of taking a picture of oneself with a mobile phone, placing the subject center-stage, has exploded in popularity in recent years, with everyone from Britain's Queen Elizabeth II to U.S. President Barack Obama joining in.

But the selfie has also inspired a spate of risk-taking and offensive public behavior, pushing the boundaries of safety and decorum, whether by dangling from a skyscraper or posing with live explosives.
