Subway Cars, The Atlantic Ocean
NYC is known for many things, but many people know this city for its impressive public transportation system. Subway cars are the main mode of transportation throughout the city, but these cars eventually get retired. In partnership with the government, The Metropolitan Transit Authority decided to repurpose these cars and sent about 2500 of them into the waters off the coast of New Jersey, South Carolina, Georgia, and other states. The cars were first decontaminated and striped of harmful materials to create a safe aquatic environment for marine life.
