It's Alive with Brad Leone is back for episode 77 and this time he's learning all about oyster reefs. Join Brad in New York Harbor as he learns how oyster shells are put to work after restaurants dispose of them. New York Harbor used to have 220,000 acres of oyster reefs, but it only took 100 years to use them all up once Europeans arrived. That's where Billion Oyster Project comes in -- recreating New York's lost oyster fields. And Brad's here to help.
