The second part of this three-part series, revealing the astonishing daily systems that allow America's biggest and busiest city to function. Anita Rani, Ade Adepitan, Ant Anstead and Dan Snow are in New York. From their base at the New Fulton fish market in The Bronx, they reveal the hidden nighttime operations, hard-nosed negotiations and price fluctuations of this wholesale operation. It is a stock exchange for seafood.

This time, Anita, Ade and Ant trace New York's food back to its source. Ade discovers that New York state produces an astonishing 600,000 tonnes of apples, more than 2.5 times Britain's entire production. Anita visits a cattle farm that supplies the steakhouses of New York and finds their diet includes chocolate, crisps and pasta.

Ant visits the New New York Bridge - a $4 billion project that will provide a new transport artery for the city. Dan Snow heads to Freshkills on Staten Island. Once the world's biggest landfill with 150 million tonnes of rubbish, it has been transformed into 2,200 acres of parkland.

And we report on the revolution overtaking New York's food delivery networks. Our cameras go out with the takeaway delivery drivers responsible for getting 180,000 chicken wings to hungry New Yorkers.
