For example, the UN High Commission for Refugees helps to alleviate the problems of displaced persons, the World Food Program provides assistance to malnourished children, and the World Health Organization supports the public health information systems that are crucial for dealing with threats from pandemics like avian flu. The UN does not have the resources to solve the problems in new areas like AIDS or global climate change, but it can play an important convening role in galvanizing the actions of governments.
