Why did New York throw 2500 metro wagons in the ocean? (The reason will surprise you)

Between 2001 and 2010 the city of New York has undertaken an unusual but highly beneficial initiative for the environment: the deposit of about 2,500 abandoned metro wagons in the Atlantic Ocean. This project, known as “MTA Artificial Reefing Program”, was intended to Create artificial coral reefs to encourage marine biodiversity and protect the coasts from erosion.

Before being submerged, the wagons were subjected to a careful reclamation process. All potentially polluting materials, such as oils, windows, seats and plastic components, have been removed, leaving only the metal structure. Once cleaned, the wagons were transported on barge and sunk in strategic areas Along the coast of the United States, from New Jersey to Georgia.

The principle behind this operation is simple but effective: solid structures immersed in the seabed provide ideal support for the growth of corals, sponges and algaecreating natural habitats for numerous species of fish and invertebrates. In a short time, these artificial wrecks become real oases of marine life, increasing biodiversity in areas otherwise poor in resources. According to experts, artificial barriers can produce up to 400 times more food for fish compared to the sandy seabed.

The waste transformed into resources for nature

In addition to the obvious environmental benefits, the project also had a positive impact on the local economy. The new barriers have attracted Underwater and biology fans navycontributing to underwater tourism, while the increase in marine fauna has favored fishing activity. In addition, the presence of these submarine structures helps to stabilize marine sediments, reducing coastal erosion.

The authorities carefully monitored the effects of the initiative, verifying the safety of the diving areas and the growth of marine ecosystems. The results have been encouraging: the populations of fish and invertebrates have increasedshowing that the intelligent reuse of industrial materials can turn into a precious resource for the environment.

Although the project ended in 2010, its impact continues to be felt. The metro vagons, once crowded with passengers in the New York tunnels, now host A myriad of marine creatures. This initiative represents a concrete example of how man can intervene positively on ecosystems, transforming waste into resources for nature.
