Why ships, tanks and subway cars are sent to the bottom of the ocean (28 photos)
When you see this photo collection, you may have exactly a question. Why deliberately litter with giant iron machines and boats in the ocean? But what about marine life? The answer is extremely elegant and simple. 
The number of coral reefs in the world is declining and this is a serious problem. The so-called artificial reefs are designed to solve it. They are provide an extra hard surface on which to attach algae and various invertebrates. And this is the place habitat, and a source of food for marine life, in general - life. BUT also an opportunity to support dying coral reefs and help them recover.
It turns out that everything is used to create these artificial reefs. old, unnecessary, scrapped ships, boats, train cars, even heavy military equipment. Instead of selling them for scrap, they used to help the environment and stimulate underwater vegetation and the prosperity of marine life. Here are a few interesting photographs of objects that were used for this purpose.
This wreck is home to over 113 different fish species.

And further. After the explosion, the ship took 1 minute 54 seconds to sink. 
Here are the bubbles on the surface after it sank

They are thrown into the water. They will also turn into artificial reefs
