After Hurricane Sandy hit the East Coast last October, I read an op-ed by Paul Greenberg in the New York Times titled “An Oyster in the Storm” that inspired me. In his piece, he described how oysters can be used to protect the shorelines of our coastal cities while improving the water quality of America’s largest metropolis. The solution to two major issues seemed suddenly so obvious. I needed to learn more.
So I partnered with a friend to produce a short documentary titled “Harbor Heroes” about the importance of oysters to New York City. We interviewed an amazing group of individuals including students from the aquaculture program at the New York Harbor School, Philippe Cousteau and Paul Greenberg himself.
How do oysters help water quality?
The idea behind restoring New York’s oysters is this: oysters grow on top of one another, forming nurseries for baby fish and creating a base structure for reefs. Reefs act as natural surge protectors and reduce the size of waves during big storms. Like other mollusks, oysters are filter-feeders, which means they clean the water column as they eat. If the water quality improves enough, sea grass could grow and create a root network that would prevent the erosion of the shoreline.
