Underwater building boom!
If you think subway cars are only useful as long as they get you to your destination, think again. Hundreds of New York’s retired subway cars are being sent to the bottom of the sea, with a mission in mind.
Redbird Reef (named after NY's red subway cars) off the coast of Delaware, boasts a artificial reef created from the wrecked subway cars. They are helping to transform a infertile part of the ocean into a lavish haven for a multitude of marine life. The walls are covered in sea grasses, blue mussels and sponges. Tuna, mackerel and sea bass use the reef as a fertile hunting ground as well as a home.
To date, almost 700 subway cars contributed in creating this underwater building boom.
