The United Nations (UN) is an important international organization formed in 1945 to settle disagreements, improve living standards, and maintain global peace. The UN has set goals to reduce poverty, halt the spread of AIDS, and provide primary education worldwide by 2015. Some key UN agencies that work on humanitarian issues include the UNICEF, the Food and Agriculture Organization, and the World Health Organization. Urbanization is increasing population density in cities and causing issues like overcrowding, crime, and the growth of slums.
