                       Zoo Protects Animals from Weather

   by Deborah Block

   It's been a cold winter across much of the United States. While humans
   can put on coats or stay warm inside, animals in zoos need to be
   protected, both from the winter cold and heat in the summer. VOA's
   Deborah Block visited the Smithsonian National Zoo in Washington to
   find out how the animals are kept comfortable all year long.
