The Problem Economic inequality and social injustice. According to the World Bank, around 702 million people worldwide live in extreme poverty, defined as living on less than US$1.90 a day. For those living in extreme poverty, it is difficult or impossible to secure adequate food and shelter, let alone access to education and basic health care. The global poor and politically disenfranchised are particularly vulnerable to the effects of conflicts, natural disasters, and climate change. Women and girls, and racial and sexual minorities who live in extreme poverty are especially vulnerable to abuse and disenfranchisement.
