Photographer Stephen Mallon captured this series of pictures over three years to document the unusual methods that New York City uses to dispose of its subway cars, but before you jump to conclusions, be sure to scroll all the way to the bottom, because this dumping has a secret purpose!
New York City has developed a special way to get rid of broken-down subway cars
Custom barges are loaded high with subway cars and carried out to the cold icy depths in the middle of the ocean.
They use construction equipment to push the subway cars over the edge
The cars go over the edge one by one
It may seem like a wasteful act of reckless pollution, but there is a noble purpose behind this.
Each subway car will be left on the ocean floor, to be integrated into the ecosystem.
Over time, every surface will be covered in life, creating an artificial coral reef system.
Every metal pipe, edge, ridge, and corner provides surface area for coral ecosystem.
This is what it looks like after 5 years.
And this is after 10 years.
