How New York deals with decommissioned subway cars

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, splashing into the waters…

The cars go over the edge one by one…

It may seem like a wasteful act of reckless pollution, but there is a deeper purpose behind this odd method of disposal…

Each subway car is left on the ocean floor, to be assimilated 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.

Here’s what it looks like after 5 years…

… and here’s what it looks like after 10 years.
