The problem of the homeless has become very serious in the United States. Almost in every community, you can find homeless people. An ironical case is: in November, 1993, a woman died on a street in Washington, D. C. , file nation’s capital, and she died at a bus-stop across the street from the US Department of Housing and Urban Development.
    People become homeless for various reasons. Some may not be able to pay for the housing they used to have, because they have lost their job and cannot find another place they can afford. Others have mental disorders, or are addicted to drugs or alcohol, and there are not enough centres to care for them.
    As ways to help these people, the federal government and many communities have set up all kinds of projects. Some programs include permanent housing, training for jobs and treatment for people who are addicted to drags or alcohol. Some communities have opened centres that offer services for as many as 700 people. The homeless can stay as long as they want.
    People are making efforts to solve the problem. However, it will not be easy, because it is a personal and economic problem as well as a social problem.
