'The lungs of Manhattan', Central Park.

Anyone seeing Hollywood's typical portrayal of Central Park over the years would imagine that it is a haven for muggers and rapists, whereas it is, in fact, a haven for nature, with 26,000 trees, huge lakes and meadows, and is home to 260 species of bird. 25 million humans a year get to use the 9,000 benches, as well as cafés, restaurants, baseball pitches, boating lakes, skate rinks, tennis courts and rental bicycles.
