New York City Mayor Michael Bloomberg has opened 10 new homeless shelters in recent months to combat a growing crisis of homelessness. More than 46,000 people are seeking shelter every night in the city's shelters...A recent census report found the city harbors 14 percent of the nation's homeless. The crisis stems from a lack of affordable housing and the city's wide gap between the rich and the poor. New York is required by law to provide shelter to every person who seeks it. The city has been using its power of emergency authority to create shelters quickly. That's upsetting residents in wealthy neighborhoods like the Upper West Side, where a homeless shelter opened in August across the street from an elementary school.
