How did new naval technology impact world war 1?

As World-war-1 began in Europe in the year of 1914, naval strength was widely considered a key factor. Yet half of the million people died because of the war impact.

Explanation:

Germany started expanding its fleet to challenge the dominance of Britain's naval  power in the ten years before the war. This race of arms was quoted as one of the war Causes.

In fact, the sea power in the war was crucial. A blockade has denied Germany and Austria food and arms by the same sea power. In the end, hunger and malnutrition had caused the deaths of up to half a million Central Powers.
