the new 21st century challenge

A new United Nations High Commission for Refugees (UNHCR) analysis reports that there were more than 45 million displaced people at the end of 2012, the highest number in almost two decades. While that may seem a tiny on a planet of 7 billion, look at it this way: one in every 200 people on earth has been displaced. No wonder the UN agency calls displacement 'the new 21st century challenge.'
