Why can't the Titanic be recovered from the bottom of the oceane

The transatlantic Titanic was the largest ship of its time, but its life was very short. The first and only voyage of the ship began April 10, 1912 and ended 4 days later. This tragedy occurred on the night of April 14-15, 1912. When the Titanic crashed, at least 1,496 people died, making this disaster one of the largest shipwrecks in history. Among the passengers of the ship were some of the richest people in the world, as well as immigrants from Ireland, Great Britain and Scandinavia, who were heading to the United States in search of a better life.
