Five-year-old Marjan sniffles from the cold as she struggles under her load. Hoisted on her back is a bag almost as big as she is.
Instead of going to school, Marjan scavenges for hours with her 10-year-old aunt collecting trash. It is a heavy burden for such a small child but a necessary one. The trash she collects is what her family uses as fuel for cooking and, more importantly, to fend off Kabul's bitter winter.
It is a matter of life and death for someone so young.
UNICEF, the UN children's agency, says that Afghanistan is the worst place in the world to be a child. One in five children do not live past the age of five. Afghanistan is second only to Sierra Leone when it comes to child mortality. Most of those deaths are caused by curable childhood diseases and malnutrition, compounded by the security situation, which means that parents are unable to access proper health care.
