چرا یک گروه هزاران صدف را به بندر نیویورک بازگرداندند؟

The Billion Oyster Project dumps oyster shells on Governors Island every week to help restore the reefs that used to thrive in the harbor. The program collects empty oyster shells from seafood restaurants across New York. We visit Governors Island to see how these shells are prepped for life again in the harbor.
