Food sustainability - beekeeping in New York
A New York market is selling honey produced on the rooftops of the city's skyscrapers. Andrew Cotay is the guru of urban beekeeping in the Big Apple. He has successfully campaigned to legalize beekeeping in the centre of New York. But it's not just about the honey. Bees pollinate the flowers of New York's many urban parks and gardens. They are essential to the future of the city's plant life. They also keep New Yorkers in touch with nature, whilst producing food that has almost no carbon footprint.
