context_page_description: The Billion Oyster Project is a citizen science project co-ordinated by the New York Harbor School with the goal of restoring one billion live oysters to New York Harbor by 2035. The project aims to engage hundreds of thousands of school children during its lifetime in marine restoration-based STEM education programs. The project grew out of the activities of students at the New York Harbor School who started growing and restoring oysters in New York Harbor in 2008.
context_section_description: As of November 2019, more than 30 million oysters had been restored to NY Harbor, with 7 acres (28,000 m²) of reef area restored. More than 6,000 high school and middle school students have taken part in the project. Approximately  of oyster shell have been recycled. Co-ordinators estimate the oysters have filtered approximately 10.9 trillion US gallons (41×10¹² L) of water in New York Harbor, removing 6.75 million pounds (3.06×10⁶ kg) million pounds of nitrogen. In 2020, expansion into mobile spawning tanks at Red Hook, Brooklyn, allowed for significant increased in capacity by the organization.
